This application claims priority to Chinese Patent Application No. 202410549402.0, filed on April 30, 2024, entitled "A Communication Method and Apparatus", the entire contents of which are incorporated herein by reference.

Technical Field

This application relates to the field of communication technology, and in particular to a communication method and apparatus.

Background Technology

With the continuous evolution of communication technology, using wireless networks for data services has become one of the important methods of data transmission. In wireless networks, the frequency bands used in Wireless Local Area Networks (WLANs) have expanded from licensed bands to unlicensed bands. Licensed bands refer to the spectrum range that requires a specific spectrum license to use, while unlicensed bands refer to the spectrum range that can be used without a specific spectrum license. How to use licensed and unlicensed bands for data transmission still requires further research.

Summary of the Invention

This application provides a communication method and apparatus that can achieve 100MHz data transmission and improve spectrum utilization.

In a first aspect, embodiments of this application provide a communication method, which can be executed by a first device. The first device can refer to the device itself, or a processor, module, chip, or chip system within the first device that implements the method. In this method, the first device generates a first physical layer protocol data unit (PPDU). The first PPDU includes bandwidth field indication information, which indicates that the bandwidth of the first PPDU is 100MHz. The first device transmits the first PPDU using a 100MHz channel.

As can be seen, in this embodiment of the application, the first device transmits a first PDDU with a bandwidth of 100MHz using a 100MHz channel, which enables data transmission at 100MHz. Compared with the first device using PPDU, which is defined by the protocol, this method can improve spectrum utilization.

One possible implementation is that the bandwidth field indicates the bandwidth information. Another possible implementation is that the first PPDUB includes a general signaling field, which includes a bandwidth field used to indicate that the bandwidth of the first PPDUB is 100MHz.

In one optional implementation, 80MHz of 100MHz corresponds to a 996-tone resource unit (RU), and 20MHz corresponds to a 242-tone RU. Thus, a 100MHz channel may include 996+242-tone multiple resource units (MRUs). For example, a 100MHz channel transmitting the first PPDU may include 996+242-tone MRUs.

It can be seen that when there is no puncturing in 100MHz, the 100MHz channel for transmitting the first PPDU can include 996+242-tone MRU.

In another optional implementation, 40MHz of the 100MHz corresponds to one 484-tone RU, and the remaining three 20MHz correspond to one 242-tone RU respectively. Thus, the 100MHz channel may include one 484-tone RU and three 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484-tone RU and three 242-tone RUs.

In another alternative implementation, five 20MHz channels in the 100MHz range each correspond to one 242-tone RU, so the 100MHz channel can include five 242-tone RUs, for example, the 100MHz channel for transmitting the first PPDU includes five 242-tone RUs.

In another optional implementation, the two 40MHz channels in the 100MHz range each correspond to a 484-tone RU, and the other 20MHz channel corresponds to a 242-tone RU. Thus, the 100MHz channel may include a 242-tone RU and two 484-tone RUs. For example, the 100MHz channel for transmitting the first PPDU may include a 242-tone RU and two 484-tone RUs.

In another optional implementation, 80MHz of the 100MHz corresponds to a 996-tone RU and 20MHz corresponds to a 242-tone RU, so the 100MHz channel may include a 242-tone RU and a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and a 996-tone RU.

In another optional implementation, 60MHz of the 100MHz corresponds to a 484+242-tone MRU, and 40MHz corresponds to a 484-tone RU. Thus, the 100MHz channel may include a 484+242-tone MRU and a 484-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

In another optional implementation, 60MHz of the 100MHz corresponds to one 484+242-tone MRU, and the remaining two 20MHz correspond to one 242-tone RU respectively. Thus, the 100MHz channel may include one 484+242-tone MRU and two 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484+242-tone MRU and two 242-tone RUs.

It is evident that when there is no puncturing in 100MHz, the RU/MRU included in the 100MHz channel for transmitting the first PPDU can be obtained by combining one or more RU/MRUs as defined in the protocol, which can reduce the complexity of implementation.

In one optional implementation, 20MHz of the 100MHz band is punched. In this method, the first PPDU further includes punched field indication information, which indicates that 20MHz of the 100MHz band is punched, and that the 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the 20MHz band is not the highest 20MHz band of the 100MHz band.

One possible implementation is that the puncturing field indicates information as a puncturing field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncturing field, the puncturing field indicating that 20MHz within 100MHz is punctured, and the 20MHz is located within the lowest 80MHz of the 100MHz.

In one optional implementation, when 20MHz of the 100MHz is punctured, the 40MHz of the 100MHz that is not punctured can correspond to a 484-tone MRU, and the other two 200MHz that are not punctured can each correspond to a 242-tone RU. Thus, the 100MHz channel can include 484+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRUs.

In another optional implementation, when 20MHz of the 100MHz is punctured, the two 40MHz channels that are not punctured in the 100MHz can each correspond to a 484-tone MRU, and the two 40MHz channels that are not punctured can be continuous or non-contiguous. Thus, the 100MHz channel can include 484+484-tone MRU. For example, the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU can be continuous or non-contiguous.

In another optional implementation, when 20MHz of 100MHz is punctured, the 80MHz of 100MHz that is not punctured can correspond to a 996-tone RU. The 80MHz that is not punctured can be continuous or discontinuous, so the 100MHz channel can include a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU can be continuous or discontinuous.

It can be seen that when 20MHz of 100MHz is punctured, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 996-tone RU.

In another alternative implementation, 40MHz of the 100MHz band is punched. In this method, the first PPDU also includes punch field indication information, which indicates that 40MHz of the 100MHz band is punched, and that the 40MHz band is within the lowest 80MHz band of the 100MHz band, or that the 40MHz band does not include the highest 20MHz band of the 100MHz band.

One possible implementation is that the puncturing field indicates information as a puncturing field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncturing field, the puncturing field indicating that 40MHz within 100MHz is punctured, and the 40MHz is located within the lowest 80MHz of the 100MHz.

In one optional implementation, when 40MHz of 100MHz is punctured, the 60MHz of 100MHz that is not punctured can correspond to a 484+242-tone MRU, so the 100MHz channel can include a 484+242-tone MRU. For example, the 100MHz channel for transmitting the first PPDU can include a 484+242-tone MRU.

In another optional implementation, when 40MHz of 100MHz is punctured, each 20MHz of 100MHz that is not punctured can correspond to a 242-tone MRU, so the 100MHz channel can include 242+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 242+242+242-tone MRUs.

It can be seen that when 40MHz of 100MHz is punched, the 100MHz channel for transmitting the first PPDU can include 484+242-tone MRU, or the 100MHz channel for transmitting the first PPDU can include 242+242+242-tone MRU.

In one optional implementation, the transmission mode of the first PPDU is non-orthogonal frequency division multiple access transmission.

In another alternative implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission.

In one optional implementation, when the first PPDU is transmitted in Orthogonal Frequency Division Multiple Access (OFDMA) mode and the first PPDU also includes puncture field indication information, regardless of whether the puncture field indication information indicates that 20MHz of the 100MHz band is punctured or that 40MHz of the 100MHz band is punctured, the lowest 80MHz band of the 100MHz band corresponds to a 4-bit puncture indication, and the highest 20MHz band corresponds to a 4-bit puncture indication, with the 4-bit corresponding to the highest 20MHz band being 1111. Specifically, the 4-bit corresponding to the lowest 80MHz band of the 100MHz band is used to indicate that either 20MHz or 40MHz of the lowest 80MHz band is punctured, and the 4-bit corresponding to the highest 20MHz band is used to indicate that the highest 20MHz band is not punctured.

In one optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access (OFDMA), and when puncturing occurs in the 100MHz channel transmitting the first PPDU, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. The first and third content channels each carry three resource element allocation fields, and the second content channel carries two resource element allocation fields. The resource element allocation fields carried by the first, second, and third content channels are used to indicate the allocation of RUs or MRUs.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first and third common coding blocks each carry three resource unit allocation fields, while the second common coding block carries two resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third common coding block, and the common fields of the third content channel are located in the fourth and fifth common coding blocks. That is, the common fields of the first and third content channels can each be located in two different common coding blocks, while the common field of the second content channel can be located in one common coding block. In this implementation, the first, third, and fourth common coding blocks each carry two resource unit allocation fields, while the second and fifth common coding blocks each carry one resource unit allocation field.

In another optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access (OFDMA). When puncturing occurs in the 100MHz channel transmitting the first PPDU, the 100MHz channel for transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. The first, second, and third content channels each carry three resource unit allocation fields. The three resource unit allocation fields carried by the first and third content channels are used to indicate the allocation of RUs (Resource Units) or MRUs (Main Units). Of the three resource unit allocation fields carried by the second content channel, two are used to indicate the allocation of RUs or MRUs, and one is a reserved field, used to indicate puncturing information, or used to indicate reserved information.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first, second, and third common coding blocks each carry three resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. That is, the common fields of the first, second, and third content channels are each located in two common coding blocks. In this implementation, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one resource unit allocation field. Alternatively, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one reserved field.

In one alternative implementation, 100MHz belongs to the unlicensed frequency band of 5735MHz to 5835MHz, for example, the 100MHz used to transmit the first PPDU belongs to the unlicensed frequency band of 5735MHz to 5835MHz. This approach allows for full utilization of the unlicensed frequency band of 5735MHz to 5835MHz, thereby improving spectral efficiency.

One possible implementation is that 100MHz belongs to a licensed frequency band, for example, the 100MHz used to transmit the first PPDU belongs to a licensed frequency band. For instance, in a specific environment, if there is a relatively available 100MHz bandwidth in the licensed frequency band, the first device can make full use of this 100MHz bandwidth to transmit information, thereby improving spectrum utilization.

Secondly, embodiments of this application also provide a communication method, which can be executed by a first device. The first device can refer to the device itself, or a processor, module, chip, or chip system within the first device that implements the method. In this method, the first device generates a first physical layer protocol data unit (PPDU). The first PPDU includes bandwidth field indication information and puncturing field indication information. The bandwidth field indication information indicates that the bandwidth of the first PPDU is 160MHz, and the puncturing field indication information indicates that the highest 60MHz of the 160MHz is punctured. The first device transmits the first PPDU using the remaining 100MHz channel after puncturing the highest 60MHz of the 160MHz.

As can be seen, in this embodiment, the bandwidth field in the first PPDU generated by the first device indicates that the bandwidth of the first PPDU is 160MHz, and the puncturing field indicates that the highest 60MHz of the 160MHz is punctured. Therefore, the actual bandwidth occupied by the first PPDU is 100MHz. Thus, the first device uses the remaining 100MHz channel after puncturing the highest 60MHz of the 160MHz to transmit the first PPDU, achieving 100MHz data transmission. Compared with the first device using PPDUs with predefined protocols to transmit information, this method can improve spectrum utilization.

One possible implementation is that the bandwidth field indicates the bandwidth information. Another possible implementation is that the first PPDUB includes a general signaling field, which includes a bandwidth field used to indicate that the bandwidth of the first PPDUB is 100MHz.

One possible implementation is that the puncture field indicates information as a puncture field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncture field, the puncture field being used to indicate that the highest 60MHz in the 160MHz band has been punctured.

In one optional implementation, 80MHz of 100MHz can correspond to a 996-tone resource unit (RU), and 20MHz can correspond to a 242-tone RU. Thus, a 100MHz channel can include 996+242-tone multiple resource units (MRUs). For example, a 100MHz channel transmitting the first PPDU includes 996+242-tone MRUs.

It can be seen that when there is no puncturing in 100MHz, the 100MHz channel for transmitting the first PPDU can include 996+242-tone MRU.

In another optional implementation, 40MHz of the 100MHz can correspond to one 484-tone RU, and the remaining three 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484-tone RU and three 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484-tone RU and three 242-tone RUs.

In another alternative implementation, the five 20MHz channels in the 100MHz channel can each correspond to a 242-tone RU, so the 100MHz channel can include five 242-tone RUs, for example, the 100MHz channel for transmitting the first PPDU includes five 242-tone RUs.

In another optional implementation, the two 40MHz channels in the 100MHz channel can each correspond to a 484-tone RU, and the other 20MHz channel can correspond to a 242-tone RU. Thus, the 100MHz channel can include a 242-tone RU and two 484-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and two 484-tone RUs.

In another optional implementation, 80MHz of the 100MHz can correspond to a 996-tone RU and 20MHz can correspond to a 242-tone RU, so the 100MHz channel can include a 242-tone RU and a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and a 996-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to a 484+242-tone MRU, and 40MHz can correspond to a 484-tone RU. Thus, the 100MHz channel can include a 484+242-tone MRU and a 484-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to one 484+242-tone MRU, and the other two 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484+242-tone MRU and two 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484+242-tone MRU and two 242-tone RUs.

It is evident that when there is no puncturing in 100MHz, the RU/MRU included in the 100MHz channel for transmitting the first PPDU can be obtained by combining one or more RU/MRUs as defined in the protocol, which can reduce the complexity of implementation.

In one alternative implementation, 20MHz of the 100MHz band is punched. In this approach, the punching field indication information is also used to indicate that 20MHz of the 100MHz band is punched, and that the 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the 20MHz band is not the highest 20MHz band of the 100MHz band.

In one optional implementation, when 20MHz of the 100MHz is punctured, the 40MHz of the 100MHz that is not punctured can correspond to a 484-tone MRU, and the other two 200MHz that are not punctured can each correspond to a 242-tone RU. Thus, the 100MHz channel can include 484+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRUs.

In another optional implementation, when 20MHz of the 100MHz is punctured, the two 40MHz channels that are not punctured in the 100MHz can each correspond to a 484-tone MRU, and the two 40MHz channels that are not punctured can be continuous or non-contiguous. Thus, the 100MHz channel can include 484+484-tone MRU. For example, the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU can be continuous or non-contiguous.

In another optional implementation, when 20MHz of 100MHz is punctured, the 80MHz of 100MHz that is not punctured can correspond to a 996-tone RU. The 80MHz that is not punctured can be continuous or discontinuous, so the 100MHz channel can include a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU can be continuous or discontinuous.

It can be seen that when 20MHz of 100MHz is punctured, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 996-tone RU.

In another alternative implementation, 40MHz of the 100MHz band is punched. In this approach, the punching field indication information is also used to indicate that 40MHz of the 100MHz band is punched, and that the 40MHz band is within the lowest 80MHz band of the 100MHz band, or that the 40MHz band does not include the highest 20MHz band of the 100MHz band.

In one optional implementation, when 40MHz of 100MHz is punctured, the 60MHz of 100MHz that is not punctured can correspond to a 484+242-tone MRU, so the 100MHz channel can include a 484+242-tone MRU. For example, the 100MHz channel for transmitting the first PPDU can include a 484+242-tone MRU.

In another optional implementation, when 40MHz of 100MHz is punctured, each 20MHz of 100MHz that is not punctured can correspond to a 242-tone MRU, so the 100MHz channel can include 242+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 242+242+242-tone MRUs.

It can be seen that when 40MHz of 100MHz is punched, the 100MHz channel for transmitting the first PPDU can include 484+242-tone MRU, or the 100MHz channel for transmitting the first PPDU can include 242+242+242-tone MRU.

In one optional implementation, the transmission mode of the first PPDU is non-orthogonal frequency division multiple access transmission.

In another alternative implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission.

In one optional implementation, when the first PPDU is transmitted in Orthogonal Frequency Division Multiple Access (OFDMA) mode and also includes puncture field indication information, regardless of whether the puncture field indication information indicates that 20MHz of 100MHz is punctured or 40MHz of 100MHz is punctured, the lowest 80MHz of 160MHz corresponds to a 4-bit puncture indication, and the highest 80MHz corresponds to a 4-bit puncture indication, with the 4-bit corresponding to the highest 80MHz being 1000. Specifically, the 4-bit corresponding to the lowest 80MHz of 160MHz is used to indicate that 20MHz or 40MHz of that lowest 80MHz is punctured, and the 4-bit corresponding to the highest 80MHz is used to indicate that the highest 60MHz of that highest 80MHz is punctured.

In one optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access (OFDMA), and when puncturing occurs in the 100MHz channel transmitting the first PPDU, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. The first, second, and third content channels each carry four resource unit allocation fields. Of the four resource unit allocation fields carried by the first and third content channels, three are used to indicate the allocation of RUs or MRUs, and one is a reserved field, used to indicate puncturing information, or used to indicate reserved information. Of the four resource unit allocation fields carried by the second content channel, two are used to indicate the allocation of RUs or MRUs, and two are reserved fields, used to indicate puncturing information, or used to indicate reserved information.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first, second, and third common coding blocks each carry four resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. That is, the common fields of the first, second, and third content channels can each be located in two separate common coding blocks. In this implementation, the first, second, third, fourth, fifth, and sixth common coding blocks each carry two resource unit allocation fields.

In one alternative implementation, the 100MHz transmitted for the first PPDU falls within the unlicensed frequency band of 5735MHz to 5835MHz. This approach allows for full utilization of the unlicensed frequency band of 5735MHz to 5835MHz, thereby improving spectral efficiency.

One possible implementation is that the 100MHz bandwidth for transmitting the first PPDU belongs to a licensed frequency band. For example, in a specific environment, if there is a relatively available 100MHz bandwidth in the licensed frequency band, the first device can make full use of this 100MHz bandwidth to transmit information, thereby improving spectrum utilization.

Thirdly, embodiments of this application provide a communication method corresponding to the communication method of the first aspect. This method can be executed by a second device, which can refer to the second device itself or a processor, module, chip, or chip system within the second device that implements the method. In this method, the second device receives a first physical layer protocol data unit (PPDU), which includes bandwidth field indication information indicating that the bandwidth of the first PPDU is 100MHz. The second device then parses the first PPDU.

As can be seen, in this embodiment of the application, the second device receives a first PPDU with a bandwidth of 100MHz, enabling data transmission at 100MHz. Compared with the second device receiving a PPDU with a predefined protocol, this method improves spectrum utilization.

One possible implementation is that the bandwidth field indicates the bandwidth information. Another possible implementation is that the first PPDUB includes a general signaling field, which includes a bandwidth field used to indicate that the bandwidth of the first PPDUB is 100MHz.

In one optional implementation, 80MHz of 100MHz can correspond to a 996-tone resource unit (RU), and 20MHz can correspond to a 242-tone RU. Thus, a 100MHz channel can include 996+242-tone multiple resource units (MRUs). For example, a 100MHz channel transmitting the first PPDU includes 996+242-tone MRUs.

It can be seen that when there is no puncturing in 100MHz, the 100MHz channel for transmitting the first PPDU can include 996+242-tone MRU.

In another optional implementation, 40MHz of the 100MHz can correspond to one 484-tone RU, and the remaining three 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484-tone RU and three 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484-tone RU and three 242-tone RUs.

In another alternative implementation, the five 20MHz channels in the 100MHz channel can each correspond to a 242-tone RU, so the 100MHz channel can include five 242-tone RUs, for example, the 100MHz channel for transmitting the first PPDU includes five 242-tone RUs.

In another optional implementation, the two 40MHz channels in the 100MHz channel can each correspond to a 484-tone RU, and the other 20MHz channel can correspond to a 242-tone RU. Thus, the 100MHz channel can include a 242-tone RU and two 484-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and two 484-tone RUs.

In another optional implementation, 80MHz of the 100MHz can correspond to a 996-tone RU and 20MHz can correspond to a 242-tone RU, so the 100MHz channel can include a 242-tone RU and a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and a 996-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to a 484+242-tone MRU, and 40MHz can correspond to a 484-tone RU. Thus, the 100MHz channel can include a 484+242-tone MRU and a 484-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to one 484+242-tone MRU, and the other two 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484+242-tone MRU and two 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484+242-tone MRU and two 242-tone RUs.

It is evident that when there is no puncturing in 100MHz, the RU/MRU included in the 100MHz channel for transmitting the first PPDU can be obtained by combining one or more RU/MRUs as defined in the protocol, which can reduce the complexity of implementation.

In one optional implementation, 20MHz of the 100MHz band is punched. In this method, the first PPDU further includes punched field indication information, which indicates that 20MHz of the 100MHz band is punched, and that the 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the 20MHz band is not the highest 20MHz band of the 100MHz band.

One possible implementation is that the puncturing field indicates information as a puncturing field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncturing field, the puncturing field indicating that 20MHz within 100MHz is punctured, and the 20MHz is located within the lowest 80MHz of the 100MHz.

In one optional implementation, when 20MHz of the 100MHz is punctured, the 40MHz of the 100MHz that is not punctured can correspond to a 484-tone MRU, and the other two 200MHz that are not punctured can each correspond to a 242-tone RU. Thus, the 100MHz channel can include 484+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRUs.

In another optional implementation, when 20MHz of the 100MHz is punctured, the two 40MHz channels that are not punctured in the 100MHz can each correspond to a 484-tone MRU, and the two 40MHz channels that are not punctured can be continuous or non-contiguous. Thus, the 100MHz channel can include 484+484-tone MRU. For example, the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU can be continuous or non-contiguous.

In another optional implementation, when 20MHz of 100MHz is punctured, the 80MHz of 100MHz that is not punctured can correspond to a 996-tone RU. The 80MHz that is not punctured can be continuous or discontinuous, so the 100MHz channel can include a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU can be continuous or discontinuous.

It can be seen that when 20MHz of 100MHz is punctured, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 996-tone RU.

In another alternative implementation, 40MHz of the 100MHz band is punched. In this method, the first PPDU also includes punch field indication information, which indicates that 40MHz of the 100MHz band is punched, and that the 40MHz band is within the lowest 80MHz band of the 100MHz band, or that the 40MHz band does not include the highest 20MHz band of the 100MHz band.

One possible implementation is that the puncturing field indicates information as a puncturing field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncturing field, the puncturing field indicating that 40MHz within 100MHz is punctured, and the 40MHz is located within the lowest 80MHz of the 100MHz.

In one optional implementation, when 40MHz of 100MHz is punctured, the 60MHz of 100MHz that is not punctured can correspond to a 484+242-tone MRU, so the 100MHz channel can include a 484+242-tone MRU. For example, the 100MHz channel for transmitting the first PPDU can include a 484+242-tone MRU.

In another optional implementation, when 40MHz of 100MHz is punctured, each 20MHz of 100MHz that is not punctured can correspond to a 242-tone MRU, so the 100MHz channel can include 242+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 242+242+242-tone MRUs.

It can be seen that when 40MHz of 100MHz is punched, the 100MHz channel for transmitting the first PPDU can include 484+242-tone MRU, or the 100MHz channel for transmitting the first PPDU can include 242+242+242-tone MRU.

In one optional implementation, the transmission mode of the first PPDU is non-orthogonal frequency division multiple access transmission.

In another alternative implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission.

In one optional implementation, when the first PPDU is transmitted in Orthogonal Frequency Division Multiple Access (OFDMA) mode and the first PPDU also includes puncture field indication information, regardless of whether the puncture field indication information indicates that 20MHz of the 100MHz band is punctured or that 40MHz of the 100MHz band is punctured, the lowest 80MHz band of the 100MHz band corresponds to a 4-bit puncture indication, and the highest 20MHz band corresponds to a 4-bit puncture indication, with the 4-bit corresponding to the highest 20MHz band being 1111. Specifically, the 4-bit corresponding to the lowest 80MHz band of the 100MHz band is used to indicate that either 20MHz or 40MHz of the lowest 80MHz band is punctured, and the 4-bit corresponding to the highest 20MHz band is used to indicate that the highest 20MHz band is not punctured.

In one optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access (OFDMA), and when puncturing occurs in the 100MHz channel transmitting the first PPDU, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. The first and third content channels each carry three resource element allocation fields, and the second content channel carries two resource element allocation fields. The resource element allocation fields carried by the first, second, and third content channels are used to indicate the allocation of RUs or MRUs.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first and third common coding blocks each carry three resource unit allocation fields, while the second common coding block carries two resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third common coding block, and the common fields of the third content channel are located in the fourth and fifth common coding blocks. That is, the common fields of the first and third content channels can each be located in two different common coding blocks, while the common field of the second content channel can be located in one common coding block. In this implementation, the first, third, and fourth common coding blocks each carry two resource unit allocation fields, while the second and fifth common coding blocks each carry one resource unit allocation field.

In another optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission, and when there is puncturing in the 100MHz channel for transmitting the first PPDU, the 100MHz channel for transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and includes a third content channel in the upper 20MHz.

The first, second, and third content channels each carry three resource unit allocation fields. The three resource unit allocation fields carried by the first and third content channels are used to indicate the allocation of RUs or MRUs. Of the three resource unit allocation fields carried by the second content channel, two are used to indicate the allocation of RUs or MRUs, and one is a reserved field, used to indicate punching information, or used to indicate reserved information.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first, second, and third common coding blocks each carry three resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. That is, the common fields of the first, second, and third content channels are each located in two common coding blocks. In this implementation, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one resource unit allocation field. Alternatively, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one reserved field.

In one alternative implementation, 100MHz belongs to the unlicensed frequency band of 5735MHz to 5835MHz, for example, the 100MHz used to transmit the first PPDU belongs to the unlicensed frequency band of 5735MHz to 5835MHz. This approach allows for full utilization of the unlicensed frequency band of 5735MHz to 5835MHz, thereby improving spectral efficiency.

One possible implementation is that 100MHz belongs to a licensed frequency band, for example, the 100MHz used to transmit the first PPDU belongs to a licensed frequency band. For instance, in a specific environment, if there is a relatively available 100MHz bandwidth in the licensed frequency band, the first device can make full use of this 100MHz bandwidth to transmit information, thereby improving spectrum utilization.

Fourthly, embodiments of this application provide a communication method corresponding to the communication method of the second aspect. This method can be executed by a second device, which can refer to the second device itself or a processor, module, chip, or chip system within the second device that implements the method. In this method, the second device receives a first physical layer protocol data unit (PPDU). The first PPDU includes bandwidth field indication information and puncturing field indication information. The bandwidth field indication information indicates that the bandwidth of the first PPDU is 160MHz, and the puncturing field indication information indicates that the highest 60MHz of the 160MHz is punctured. The second device parses the first PPDU.

As can be seen, in this embodiment, the bandwidth field indication information of the first PPDU received by the second device indicates that the bandwidth of the first PPDU is 160MHz, and the puncturing field indication information indicates that the highest 60MHz of the 160MHz is punctured. Therefore, the first PPDU received by the second device actually occupies 100MHz of bandwidth, realizing 100MHz data transmission. Compared with the second device receiving PPDUs with a predefined protocol, this method can improve spectrum utilization.

One possible implementation is that the bandwidth field indicates the bandwidth information. Another possible implementation is that the first PPDUB includes a general signaling field, which includes a bandwidth field used to indicate that the bandwidth of the first PPDUB is 100MHz.

One possible implementation is that the puncture field indicates information as a puncture field. Another possible implementation is that the first PPDU includes a general signaling field, the general signaling field packet including the puncture field, the puncture field being used to indicate that the highest 60MHz in the 160MHz band has been punctured.

In one optional implementation, 80MHz of 100MHz can correspond to a 996-tone resource unit (RU), and 20MHz can correspond to a 242-tone RU. Thus, a 100MHz channel can include 996+242-tone multiple resource units (MRUs). For example, a 100MHz channel transmitting the first PPDU includes 996+242-tone MRUs.

It can be seen that when there is no puncturing in 100MHz, the 100MHz channel for transmitting the first PPDU can include 996+242-tone MRU.

In another optional implementation, 40MHz of the 100MHz can correspond to one 484-tone RU, and the remaining three 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484-tone RU and three 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484-tone RU and three 242-tone RUs.

In another alternative implementation, the five 20MHz channels in the 100MHz channel can each correspond to a 242-tone RU, so the 100MHz channel can include five 242-tone RUs, for example, the 100MHz channel for transmitting the first PPDU includes five 242-tone RUs.

In another optional implementation, the two 40MHz channels in the 100MHz channel can each correspond to a 484-tone RU, and the other 20MHz channel can correspond to a 242-tone RU. Thus, the 100MHz channel can include a 242-tone RU and two 484-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and two 484-tone RUs.

In another optional implementation, 80MHz of the 100MHz can correspond to a 996-tone RU and 20MHz can correspond to a 242-tone RU, so the 100MHz channel can include a 242-tone RU and a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 242-tone RU and a 996-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to a 484+242-tone MRU, and 40MHz can correspond to a 484-tone RU. Thus, the 100MHz channel can include a 484+242-tone MRU and a 484-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU.

In another optional implementation, 60MHz of the 100MHz can correspond to one 484+242-tone MRU, and the other two 20MHz can each correspond to one 242-tone RU. Thus, the 100MHz channel can include one 484+242-tone MRU and two 242-tone RUs. For example, the 100MHz channel for transmitting the first PPDU includes one 484+242-tone MRU and two 242-tone RUs.

It is evident that when there is no puncturing in 100MHz, the RU/MRU included in the 100MHz channel for transmitting the first PPDU can be obtained by combining one or more RU/MRUs as defined in the protocol, which can reduce the complexity of implementation.

In one alternative implementation, 20MHz of the 100MHz band is punched. In this approach, the punching field indication information is also used to indicate that 20MHz of the 100MHz band is punched, and that the 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the 20MHz band is not the highest 20MHz band of the 100MHz band.

In one optional implementation, when 20MHz of the 100MHz is punctured, the 40MHz of the 100MHz that is not punctured can correspond to a 484-tone MRU, and the other two 200MHz that are not punctured can each correspond to a 242-tone RU. Thus, the 100MHz channel can include 484+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRUs.

In another optional implementation, when 20MHz of the 100MHz is punctured, the two 40MHz channels that are not punctured in the 100MHz can each correspond to a 484-tone MRU, and the two 40MHz channels that are not punctured can be continuous or non-contiguous. Thus, the 100MHz channel can include 484+484-tone MRU. For example, the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU can be continuous or non-contiguous.

In another optional implementation, when 20MHz of 100MHz is punctured, the 80MHz of 100MHz that is not punctured can correspond to a 996-tone RU. The 80MHz that is not punctured can be continuous or discontinuous, so the 100MHz channel can include a 996-tone RU. For example, the 100MHz channel for transmitting the first PPDU includes a 996-tone RU, and the 996 subcarriers in the 996-tone RU can be continuous or discontinuous.

It can be seen that when 20MHz of 100MHz is punctured, the 100MHz channel for transmitting the first PPDU includes 484+242+242-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 484+484-tone MRU, or the 100MHz channel for transmitting the first PPDU includes 996-tone RU.

In another alternative implementation, 40MHz of the 100MHz band is punched. In this approach, the punching field indication information is also used to indicate that 40MHz of the 100MHz band is punched, and that the 40MHz band is within the lowest 80MHz band of the 100MHz band, or that the 40MHz band does not include the highest 20MHz band of the 100MHz band.

In one optional implementation, when 40MHz of 100MHz is punctured, the 60MHz of 100MHz that is not punctured can correspond to a 484+242-tone MRU, so the 100MHz channel can include a 484+242-tone MRU. For example, the 100MHz channel for transmitting the first PPDU can include a 484+242-tone MRU.

In another optional implementation, when 40MHz of 100MHz is punctured, each 20MHz of 100MHz that is not punctured can correspond to a 242-tone MRU, so the 100MHz channel can include 242+242+242-tone MRUs. For example, the 100MHz channel for transmitting the first PPDU includes 242+242+242-tone MRUs.

It can be seen that when 40MHz of 100MHz is punched, the 100MHz channel for transmitting the first PPDU can include 484+242-tone MRU, or the 100MHz channel for transmitting the first PPDU can include 242+242+242-tone MRU.

In one optional implementation, the transmission mode of the first PPDU is non-orthogonal frequency division multiple access transmission.

In another alternative implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access transmission.

In one optional implementation, when the first PPDU is transmitted in Orthogonal Frequency Division Multiple Access (OFDMA) mode and also includes puncture field indication information, regardless of whether the puncture field indication information indicates that 20MHz of 100MHz is punctured or 40MHz of 100MHz is punctured, the lowest 80MHz of 160MHz corresponds to a 4-bit puncture indication, and the highest 80MHz corresponds to a 4-bit puncture indication, with the 4-bit corresponding to the highest 80MHz being 1000. Specifically, the 4-bit corresponding to the lowest 80MHz of 160MHz is used to indicate that 20MHz or 40MHz of that lowest 80MHz is punctured, and the 4-bit corresponding to the highest 80MHz is used to indicate that the highest 60MHz of that highest 80MHz is punctured.

In one optional implementation, the transmission mode of the first PPDU is orthogonal frequency division multiple access (OFDMA), and when puncturing occurs in the 100MHz channel transmitting the first PPDU, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. The first, second, and third content channels each carry four resource unit allocation fields. Of the four resource unit allocation fields carried by the first and third content channels, three are used to indicate the allocation of RUs or MRUs, and one is a reserved field, used to indicate puncturing information, or used to indicate reserved information. Of the four resource unit allocation fields carried by the second content channel, two are used to indicate the allocation of RUs or MRUs, and two are reserved fields, used to indicate puncturing information, or used to indicate reserved information.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. That is, the common fields of the first, second, and third content channels can each be located in a separate common coding block, saving overhead. In this approach, the first, second, and third common coding blocks each carry four resource unit allocation fields.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. That is, the common fields of the first, second, and third content channels can each be located in two separate common coding blocks. In this implementation, the first, second, third, fourth, fifth, and sixth common coding blocks each carry two resource unit allocation fields.

In one alternative implementation, the 100MHz transmitted for the first PPDU falls within the unlicensed frequency band of 5735MHz to 5835MHz. This approach allows for full utilization of the unlicensed frequency band of 5735MHz to 5835MHz, thereby improving spectral efficiency.

One possible implementation is that the 100MHz bandwidth for transmitting the first PPDU belongs to a licensed frequency band. For example, in a specific environment, if there is a relatively available 100MHz bandwidth in the licensed frequency band, the first device can make full use of this 100MHz bandwidth to transmit information, thereby improving spectrum utilization.

With the continuous development of integrated circuit technology, more and more devices can be integrated on the same chip. For example, a digital baseband processor can be integrated with multiple application processors (e.g., but not limited to graphics processors, multimedia processors, etc.) on the same chip. Such a chip can be called a system-on-a-chip (SoC). Whether the devices are disposed independently on different chips or integrated on one or more chips often depends on the needs of the product design. This application does not limit the implementation form of the above-mentioned devices.

Sixthly, embodiments of this application also provide a processor for executing the various methods described above. During the execution of these methods, the processes related to sending and receiving the aforementioned information can be understood as the processor outputting the aforementioned information and the processor receiving the input information. When outputting the aforementioned information, the processor outputs the information to a transceiver for transmission. After being output by the processor, the information may require further processing before reaching the transceiver. Similarly, when the processor receives the input information, the transceiver receives the information and inputs it to the processor. Furthermore, after the transceiver receives the information, the information may require further processing before being input to the processor.

Unless otherwise specified, or unless it contradicts its actual function or internal logic in the relevant description, the transmission and reception operations involved by the processor can be more generally understood as processor output and reception, input and other operations, rather than transmission and reception operations directly performed by radio frequency circuits and antennas.

In implementation, the processor can be a dedicated processor for executing these methods, or it can be a processor that executes computer instructions stored in memory to execute these methods, such as a general-purpose processor. The memory can be a non-transitory memory, such as read-only memory (ROM), which can be integrated with the processor on the same chip or disposed on different chips. This application does not limit the type of memory or the arrangement of the memory and the processor.

Seventhly, embodiments of this application also provide a communication system including one or more access points and one or more sites. In another possible design, the system may further include other devices/functional network elements that interact with the access points and/or sites.

Ninthly, embodiments of this application also provide a computer program product including instructions that, when run on a computer, implement the method described in any one of the first to fourth aspects.

Tenthly, embodiments of this application provide a chip system including a processor and an interface. The interface is used to acquire programs or instructions, and the processor is used to invoke the programs or instructions to implement or support a first device in implementing the functions involved in the first aspect, or to implement or support the first device in implementing the functions involved in the second aspect, or to implement or support a second device in implementing the functions involved in the third aspect, or to implement or support a second device in implementing the functions involved in the fourth aspect. For example, determining or processing at least one of the data and information involved in the above methods. In one possible design, the chip system further includes a memory for storing necessary program instructions and data for the terminal. The chip system may be composed of chips or may include chips and other discrete devices.

Detailed Implementation

The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

To better understand the embodiments of this application, the system architecture involved in the embodiments of this application will be described first below:

Please refer to Figure 1, which is a schematic diagram of a system architecture provided in an embodiment of this application. This system architecture may include one or more access points (APs) and one or more stations (STAs). The number and configuration of devices shown in Figure 1 are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. The system architecture shown in Figure 1 is illustrated using AP1, AP2, STA1, STA2, and STA3, with AP1 and AP2 providing wireless services to STA1, STA2, and STA3 as an example. In Figure 1, AP1 and AP2 are examples of base stations, and STA1, STA2, and STA3 are examples of mobile phones.

This application applies to data communication between one or more APs and one or more STAs, and also to communication between APs and between STAs.

The communication systems applicable to the embodiments of this application are wireless local area networks (WLANs) or cellular networks, or other wireless communication systems that support parallel transmission across multiple links. This application primarily uses a network deploying IEEE 802.11 as an example for illustration, but the various aspects involved can be extended to other networks employing various standards or protocols, such as Bluetooth, high-performance radio LAN (HIPERLAN) (a wireless standard similar to IEEE 802.11, primarily used in Europe), wide area networks (WANs), personal area networks (PANs), or other networks now known or to be developed in the future. Therefore, regardless of the coverage area and wireless access protocol used, the various aspects provided in this application can be applied to any suitable wireless network.

In this embodiment, the STA has wireless transceiver capabilities, supports the 802.11 series of protocols, and can communicate with the AP or other STAs. For example, the STA can be any user communication device that allows users to communicate with the AP and subsequently with the WLAN, including but not limited to: tablets, desktops, laptops, notebooks, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), mobile phones, and other network-connected user devices; IoT nodes in the Internet of Things (IoT); or in-vehicle communication devices in the Internet of Vehicles (IoV). In one possible implementation, the STA can also be the chip and processing system within these terminals.

In this embodiment, the AP is a device that provides services to the STA and can support the 802.11 series of protocols. For example, the AP can be a communication server, router, switch, bridge, or other communication entity. Alternatively, the AP can include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP can also be the chip and processing system in these various forms of devices, thereby realizing the methods and functions of this embodiment.

To facilitate understanding of the embodiments disclosed in this application, the following two points are explained.

(1) The scenario in the embodiments disclosed in this application is illustrated by taking the scenario of wireless fidelity (Wi-Fi) network in wireless communication network as an example. It should be noted that the solution in the embodiments disclosed in this application can also be applied to other wireless communication networks, and the corresponding name can also be replaced by the name of the corresponding function in other wireless communication networks.

(2) The embodiments disclosed in this application will be presented in relation to systems including multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and/or may not include all devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches may also be used.

The following describes the relevant concepts involved in the embodiments of this application:

1. Physical layer protocol data unit (PPDU).

PPDU can also be called physical layer data packet or data packet. The data field of PPDU carries media protocol data unit (MPDU) and medium access control layer protocol data unit (MAC PDU), which are commonly referred to as medium access control (MAC) frames, such as data frames, acknowledgment frames, trigger frames, beacon frames, etc.

2. Extremely high throughput multiple user physical layer protocol data unit (EHT MU PPDU).

EHT MU PPDU is a PPDU defined in 802.11be, where EHT is the standard name of 802.11be, and MU stands for multi-user, but it can support data transmission between single-user and multi-user.

Please refer to Figure 2, which is a schematic diagram of the frame structure of an EHT MU PPDU. An EHT MU PPDU includes a preamble, a data field, and a packet extension (PE). The preamble includes traditional preambles: a legacy short training field (L-SFT), a legacy long training field (L-LTF), and a legacy signal field (L-SIG), used to ensure coexistence between new and legacy devices. The L-SIG contains a length field, which indirectly indicates the duration of the portion following the L-SIG in the EHT MU PPDU. The traditional preamble also includes repeated L-SIGs (RL-SIG) to enhance the reliability of the legacy signal field. Furthermore, it provides an automatic detection method for the receiver to identify whether a data packet is an EHT PPDU by detecting whether two symbols are identical and the remainder of the length in the L-SIG. In addition, the preamble includes a universal signal field (U-SIG), which exists in the PPDU of the 802.11be standard and several subsequent generations of standards. U-SIG indicates which generation of standard the PPDU belongs to (EHT PPDU or later). If the PPDU is an EHT MU PPDU, then an EHT-SIG also exists after the U-SIG. Both U-SIG and EHT-SIG carry signaling information needed for demodulating subsequent data fields. The preamble also includes an extreme high throughput short training field (EHT-STF) and an extreme high throughput long training field (EHT-LTF), used for automatic gain control and channel estimation, respectively. Packet expansion can provide the receiver with more time to process data.

The U-SIG field of the EHT MU PPDU includes a bandwidth field, the contents of which can be found in Table 1 below:

Table 1

As can be seen from Table 1, the first symbol in the U-SIG field is the symbol corresponding to the bandwidth field. This symbol is used to indicate the bandwidth of the EHT MU PPDU. When bits B3-B5 in this symbol are set to 0 to 5 respectively, it indicates that the bandwidth of the EHT MU PPDU is 20MHz, 40MHz, 80MHz, 160MHz, 320-1MHz, and 320-2MHz respectively.

In addition, in the 802.11be physical layer preamble, the reserved/unused bits or the reserved/unused status (entry) of a certain (sub)field in the signaling field are divided into two types: Disregard and Validate, which can also be called ignore, verification, etc. For example, when the bandwidth field in Table 1 is set to 6 or 7, it is Validate, indicating a reserved/unused status.

The channel for transmitting EHT MU PPDUs supports puncturation. The punctured channel information field is also located in the U-SIG field. This field indicates the puncturation status of each 20MHz sub-channel within the PPDU transmission channel. The punctured channel information field can also be called a preamble puncturation indicator or simply a punctured field. The contents of the EHT MU PPDU's punctured channel information field are shown in Table 2 below.

Table 2

As shown in Table 2, Table 3 contains the puncturing channel information field of the U-SIG field in the EHT MU PPDU when using non-OFDMA transmission. When using OFDM transmission, a 4-bit interval is used every 80MHz to indicate the puncturing mode of the channel transmitting the EHT MU PPDU.

Table 3

In Table 3, for a given bandwidth, the value of the bandwidth field is set to the rightmost column of Table 3, which corresponds to the meaning of the middle two columns. As can be seen from Table 3, for a given bandwidth, different values in the bandwidth field represent different puncturing patterns for that bandwidth. For example, if the PPDU bandwidth is 80MHz and the bandwidth field value is set to 2, it indicates that the second 20MHz channel within the 80MHz bandwidth is punctured in order from low to high frequency; if the PPDU bandwidth is 80MHz and the bandwidth field value is set to 3, it indicates that the third 20MHz channel within the 80MHz bandwidth is punctured in order from low to high frequency.

WLAN standards have evolved from 802.11a/b/g, through 802.11n, 802.11ac (Wi-Fi 5), 802.11ax (Wi-Fi 6), 802.11be (Wi-Fi 7), and are currently under discussion for 802.11bn (Wi-Fi 8). Prior to 802.11n, the standard defined a 20MHz bandwidth. 802.11ac and 802.11ax further expanded this to 40MHz, 80MHz, 160MHz, and 80MHz+80MHz. In 802.11be, the 80MHz+80MHz bandwidth was removed, and a 320MHz bandwidth was further defined, specifically two 320MHz bandwidth categories: 320MHz-1 and 320MHz-2.

Please refer to Figure 3, which is a schematic diagram of channel partitioning. As shown in Figure 3, the channel in the 6GHz band can be divided into sub-channels with bandwidths of 80MHz, 160MHz, and 320MHz. The 320MHz sub-channels include the 320MHz-1 sub-channel with center frequencies of 31, 95, and 159 and the 320MHz-2 sub-channel with center frequencies of 63, 127, and 191.

UNII stands for the Unlicensed National Information Infrastructure (U-NII) radio band. Additionally, the 80MHz band in Figure 3 can be further composed of four 20MHz bands, where the first and second 20MHz bands, or the third and fourth 20MHz bands, can form a 40MHz band.

Furthermore, unlicensed spectrum is relatively limited. For example, in some countries and regions, there are two spectrum bands: 2.4 GHz and 5 GHz, but no 6 GHz spectrum exists. Figure 4 shows another channel allocation diagram. Specifically, Figure 4 shows a channel allocation diagram for the 5 GHz spectrum. The low-frequency portion of 5 GHz (including UNII-1 and UNII-2A), usually called 5.1 GHz, contains a maximum of 160 MHz of channels, and the standard defines spectrum resources with a bandwidth of 160 MHz. In the high-frequency portion of 5 GHz, usually called 5.8 GHz, there is a total of 100 MHz (5735 MHz - 5835 MHz) of spectrum resources in some countries and regions. However, the standard defines a maximum PPDU bandwidth of 80 MHz and below, resulting in the 5.8 GHz spectrum not being fully utilized.

In this embodiment, the first device can be an Access Point (AP) and the second device can be a Switching Station (STA). In one possible implementation, the first device can be a STA and the second device can be an AP. In another possible implementation, the first device and the second device can be different APs. In yet another possible implementation, the first device and the second device can be different STAs.

This application provides a communication method 100, and Figure 5 is an interactive schematic diagram of the communication method 100. The communication method 100 is described from the perspective of the interaction between a first device and a second device. The communication method 100 includes, but is not limited to, the following steps:

S101. The first device generates a first PPDU, the first PPDU including bandwidth field indication information, the bandwidth field indication information being used to indicate that the bandwidth of the first PPDU is 100MHz.

The bandwidth of the first PPDU is 100MHz, which can be either: the bandwidth occupied by the first PPDU is 100MHz, or the channel for transmitting the first PPDU is 100MHz.

One possible implementation is that the first PPDU includes general signaling field indication information, which includes bandwidth field indication information. Another possible implementation is that the general signaling field indication information can be a general signaling field, and the bandwidth field indication information can be a bandwidth field. That is, the first PPDU may include U-SIG, and U-SIG may include a bandwidth field, which indicates that the bandwidth of the first PPDU is 100MHz.

In one optional implementation, the first PPDU includes a U-SIG, which includes a bandwidth field. The value of the bandwidth field is set to 6 or 7. For example, Table 4 below shows the meaning of different values for the bandwidth field of the PPDU. For instance, as shown in Table 4, when the value of the bandwidth field of the first PPDU is set to 6, it indicates that the bandwidth of the first PPDU is 100MHz; when the value of the bandwidth field of the first PPDU is set to 7, it is a confirmation field, indicating a reserved/unused state. As another example, setting the value of the bandwidth field in Table 4 to 7 indicates that the bandwidth of the first PPDU is 100MHz; setting the value of the bandwidth field in Table 4 to 6 is a confirmation field, indicating a reserved/unused state.

As can be seen, when the first PPDU includes U-SIG, the first device can directly use the bandwidth field defined in U-SIG to indicate that the bandwidth of the first PPDU is 100MHz, thereby reducing indication overhead and complexity.

Table 4

In another optional implementation, the bandwidth field indication information is an extended bandwidth field. This extended bandwidth field is obtained by expanding upon the existing bandwidth field in the U-SIG, as well as some or all of the confirmation and ignore bits in the U-SIG. The value of the extended bandwidth field can be greater than or equal to 8. For example, the first device expands the existing bandwidth field in the U-SIG, along with some of the confirmation and ignore bits, to obtain an extended bandwidth field of 4 bits. Therefore, the extended bandwidth field can indicate a value from 0 to 15, and the first device can use any value from 6 to 15 to indicate that the bandwidth of the first PPDU is 100MHz.

As can be seen, the first device can also indicate that the bandwidth of the first PPDU is 100MHz based on the bandwidth field already present in the U-SIG, as well as the confirmation bit and ignore bit. This method makes the bandwidth indication of the first PPDU more flexible.

In one optional implementation, the first PPDU is an Ultra High Reliability Physical Layer Protocol Data Unit (UHR PPDU), which is the PPDU in 802.11bn, i.e., the PPDU in the Wi-Fi 8 standard. Please refer to Figure 6, which is a schematic diagram of the frame structure of a UHR PPDU. As shown in Figure 6, the UHR PPDU includes: an L-STF field for PPDU discovery, coarse synchronization, and automatic gain control; an L-LTF field for fine synchronization and channel estimation; L-SIG and RL-SIG fields for carrying signaling information related to the PPDU length, ensuring coexistence; the repetition of L-SIG and RL-SIG is also used for automatic detection at the receiver; a U-SIG field for carrying signaling for demodulating subsequent data; a vendor-specific SIG (VS-SIG) field for carrying vendor-specific signaling information; this field may be absent; and an Ultra High Reliability signaling field. The signal field (UHR-SIG) is used to carry signaling for demodulating subsequent data. This field may not exist, for example, it may not exist in a UHR TB PPDU; the ultra-high reliability short training field (UHR-STF) is used for automatic gain control; the ultra-high reliability long training field (UHR-LTF) is used for channel estimation; the data field is used to carry data information; and the PE field is used to increase the receiver's processing time.

In one possible implementation, the frame structure of the UHR PPDU may also be different from the frame structure shown in Figure 6. This application does not limit the frame structure of the UHR PPDU.

One possible implementation is that the first PPDU can be a PPDU from a standard later than 802.11bn, but this application does not limit this embodiment. For ease of explanation, the following description uses a UHR PPDU as the first PPDU.

Furthermore, the first PPDU's transmission modes include non-OFDMA transmission and OFDMA transmission. The following describes the implementation methods for the 100MHz channel for both non-OFDMA and OFDMA transmission modes:

Transmission mode 1.1: non-OFDMA transmission.

In non-OFDMA transmission, all frequency domain resources within the entire 100MHz bandwidth are allocated as a whole to a user or a group of users for transmission. This can be further divided into single-user transmission or multi-user multiple-input multiple-output (MU-MIMO) transmission.

For a 100MHz first PPDU, when using non-OFDMA transmission, the MRU in the 100MHz channel needs to be redefined. Furthermore, the 100MHz channel may or may not be punctured. If puncturing occurs, either 20MHz or 40MHz of the 100MHz channel can be punctured. Therefore, the following describes the implementation of the 100MHz channel in non-OFDMA transmission for scenarios where there are no puncturing, 20MHz is punctured, and 40MHz is punctured:

Scenario 1.11: No punch holes exist at 100MHz.

The 100MHz band has no holes, indicating that the entire 100MHz band can be used for data transmission.

In one optional implementation, when there are no puncturing operations in the 100MHz band, the lowest 80MHz band can correspond to a 996-tone RU, and the highest 20MHz band can correspond to a 242-tone RU. Therefore, if there are no puncturing operations in the 100MHz band, the 100MHz channel can include 996+242-tone MRUs; for example, the 100MHz channel transmitting the first PPDU includes 996+242-tone MRUs. For example, Figure 7 is a schematic diagram of a 100MHz channel partition. The 100MHz channel in Figure 7 has no puncturing operations, and this 100MHz channel includes 996+242-tone MRUs.

One possible implementation is that when the first PPDU is a UHR PPDU, the UHR-STF, UHR-LTF, Data, and PE in the first PPDU can be referred to as the UHR modulation part and transmitted in a 996+242-tone MRU.

One possible implementation includes, but is not limited to, at least one of the following channels, including a 996+242-tone MRU: a 160MHz channel, a 240MHz channel, a 320MHz channel, a 480MHz channel, and a 640MHz channel. That is, the 996+242-tone MRU can be an MRU format across multiple channels.

One possible implementation is that, when there is no puncturing in the 100MHz channel, the 100MHz channel can include 484+484+242-tone MRU, or it can include 484+242+242+242-tone MRU, or it can include 242+242+242+242+242-tone MRU, where the 242-tone RU is a RU corresponding to a 20MHz channel in the 100MHz channel, and the 484-tone RU is a RU corresponding to a 40MHz channel in the 100MHz channel.

Scenario 1.12: 20MHz of 100MHz is punched.

In this scenario, if 20MHz of the 100MHz channel is punctured, it means that 20MHz of that 100MHz channel has been removed and cannot be used for data transmission. Therefore, 80MHz of that 100MHz channel is actually available for data transmission. Alternatively, the puncturing of 20MHz within the 100MHz channel could mean that a 20MHz sub-channel within the 100MHz channel is punctured, for example, the 20MHz sub-channel within the 100MHz channel transmitting the first PPDU is punctured.

In this scenario, the first PPDU also includes puncture field indication information. This puncture field indication information is used to indicate that 20MHz within the 100MHz band is punctured. This 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the punctured 20MHz band is not the highest 20MHz band of the 100MHz band. Therefore, when 20MHz within the 100MHz band is punctured, the first to fourth 20MHz bands within the 100MHz band can be punctured in ascending order of frequency, or in other words, the first to fourth 20MHz sub-channels within the 100MHz channel can be punctured, resulting in a total of four puncturing modes.

One possible implementation is that the punch field indicator information is a punch field. Another possible implementation is that the first PPDU includes a U-SIG, where the U-SIG includes the punch field.

See Table 5 below, which explains the meaning of the punch field in U-SIG for OFDMA transmission mode.

Table 5

As shown in Table 5, a value of 0 in the punch field indicates that there are no punches in the 100MHz channel; a value of 1 indicates that the first 20MHz from low to high frequency in the 100MHz channel is punched; a value of 3 indicates that the second 20MHz from low to high frequency in the 100MHz channel is punched; and a value of 4 indicates that the third 20MHz from low to high frequency in the 100MHz channel is punched. Therefore, values of 1 to 4 in the punch field represent different 20MHz segments within the lowest 80MHz range of the 100MHz channel that are punched.

In one optional implementation, when 20MHz of 100MHz is punctured, there is a 484+242-tone MRU in the lowest 80MHz of 100MHz and a 242-tone RU in the highest 20MHz, so that they can be combined to form a 484+242+242-tone MRU. That is, the 100MHz channel can include a 484+242+242-tone MRU. For example, the 100MHz channel for transmitting the first PPDU includes a 484+242+242-tone MRU.

It should be noted that, in the embodiments of this application, among the MRUs included in the 100MHz channel, the larger RU is usually placed at the front of the MRUs. However, the placement of the larger RU and the smaller RUs does not represent their positions within the 100MHz channel. In the 100MHz channel, the larger RU can be located before, after, or between multiple smaller RUs.

For example, when a 100MHz channel includes 484+242+242-tone MRUs, in ascending frequency order, the 484-tone RU may be located before, after, or between the two 242-tone RUs. This embodiment does not limit the position of the 484-tone RU relative to the two 242-tone RUs. Alternatively, when a 100MHz channel includes 484+242+242-tone MRUs, the 484 subcarriers may be located before, after, or between the two 242 subcarriers. This embodiment does not limit the position of the 484 subcarriers relative to the two 242 subcarriers.

For example, Figures 8 to 11 are schematic diagrams of a 100MHz channel partitioning. As shown in Figure 8, the first 20MHz of the 100MHz channel is punctured, and the 100MHz channel includes a 484+242+242-tone MRU, with the 484 subcarriers positioned before the two 242-tone subcarriers. As shown in Figure 9, the second 20MHz of the 100MHz channel is punctured, and the 100MHz channel includes a 484+242+242-tone MRU, with the 484 subcarriers positioned between the two 242-tone subcarriers. As shown in Figure 10, the third 20MHz of the 100MHz channel is punctured, and the 100MHz channel includes a 484+242+242-tone MRU, with the 484 subcarriers positioned before the two 242-tone subcarriers. As shown in Figure 11, the fourth 20MHz in the 100MHz channel is punctured. The 100MHz channel includes a 484+242+242-tone MRU, and the 484 subcarriers are located before the two 242 subcarriers.

Furthermore, in the 100MHz channel partitioning diagrams shown in Figures 8 to 11, the RU corresponding to the highest 20MHz in the 100MHz range can be considered as an extension based on the 80MHz range already defined in the protocol. Therefore, for the 100MHz channels shown in Figures 8 to 11, the 100MHz channel includes 484+242+242-tone MRUs, which can also be replaced with: the 100MHz channel includes (484+242)+242-tone MRUs.

One possible implementation is that when the 100MHz channel includes a 484+242+242-tone MRU, the 484 subcarriers in the 484+242+242-tone MRU exist within the lowest 80MHz of the 100MHz, for example, in the 100MHz channel shown in Figures 8 to 11 above, where the 484 subcarriers exist within the lowest 80MHz of the 100MHz.

One possible implementation is that when 20MHz of a 100MHz channel is punctured, the 100MHz channel comprises a 484+242+242-tone MRU, and the 484 subcarriers within the 484+242+242-tone MRU exist within the highest 40MHz of the 100MHz channel. In other words, when the 100MHz channel comprises a 484+242+242-tone MRU, the 484-tone RU can be defined across 80MHz, or the 484 subcarriers can be defined across 80MHz, thus allowing for more flexible resource utilization.

For example, Figures 12, 13, and 14 are schematic diagrams of a 100MHz channel partitioning. In Figures 12 to 14, the first, second, and third 20MHz bands within the 100MHz band are punched, and the highest 40MHz band corresponds to a 484-tone RU, while the lowest 60MHz band corresponds to a 242+242-tone MRU. Therefore, in Figures 12 to 14, the 100MHz channel includes 484+242+242-tone MRUs, with the 484-tone RUs defined across 80MHz bands.

In another optional implementation, when 20MHz of the 100MHz channel is punctured, each consecutive 40MHz segment that is not punctured corresponds to a 484-tone MRU, thus forming a 484+484-tone MRU. That is, the 100MHz channel includes 484+484-tone MRUs; for example, the 100MHz channel transmitting the first PPDU includes 484+484-tone MRUs. The two 484 subcarriers in the 484+484-tone MRU can be consecutive or non-consecutive; or, the two 484 subcarriers in the 484+484-tone MRU can be consecutive or non-consecutive. Furthermore, if the 100MHz channel includes 484+484-tone MRUs, and one of the consecutive 484 subcarriers is located within the highest 40MHz segment of the 100MHz channel, then these consecutive 484 subcarriers can be considered to span an 80MHz range, allowing for more flexible resource utilization.

For example, Figures 15 and 16 are schematic diagrams of a 100MHz channel partitioning. As shown in Figure 15, the lowest 20MHz in the 100MHz channel is punctured. The combination of the second and third 20MHz in the 100MHz channel corresponds to a 484-tone MRU, and the combination of the fourth and fifth 20MHz corresponds to another 484-tone MRU, together forming a 484+484-tone MRU. The two 484 subcarriers are consecutive, thus the 100MHz channel includes a 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are consecutive. The 484 subcarriers located in the high-frequency band are defined across 80MHz. As shown in Figure 16, the third 20MHz in the 100MHz band is punctured. The combination of the first and second 20MHz in the 100MHz band corresponds to a 484-tone MRU, and the combination of the fourth and fifth 20MHz bands corresponds to another 484-tone MRU. Together, they form a 484+484-tone MRU, and the two 484 subcarriers are non-contiguous. Thus, the 100MHz channel includes a 484+484-tone MRU, and the two 484 subcarriers in the 484+484-tone MRU are non-contiguous. The 484 subcarriers located in the high-frequency band are defined across 80MHz.

One possible implementation involves puncturing 20MHz of a 100MHz channel, resulting in a 484+484-tone MRU. In this configuration, one of the 484 subcarriers is formed by combining two discontinuous 242 subcarriers. For example, Figures 17 and 18 illustrate one such 100MHz channel partitioning. As shown in Figure 17, when the second 20MHz of the 100MHz channel is punctured, the first and third 20MHz subcarriers can form a discontinuous 484-tone RU, where the 484 subcarriers are composed of two discontinuous 242 subcarriers. The fourth and fifth 20MHz subcarriers form a continuous 484-tone RU, thus creating a 484+484-tone MRU. The 484 subcarriers in the higher frequency band are defined across an 80MHz band.

As shown in Figure 18, the fourth 20MHz in the 100MHz is punched. The first 20MHz and the second 20MHz can form a continuous 484-tone RU, and the third 20MHz and the fifth 20MHz can form a discontinuous 484-tone RU, which can also form a 484+484-tone MRU.

In another optional implementation, when 20MHz of the 100MHz channel is punctured, the remaining 80MHz that is not punctured corresponds to a 996-tone RU. Therefore, the 100MHz channel includes a 996-tone RU. For example, the 100MHz channel transmitting the first PPDU includes a 996-tone RU. The 996 subcarriers in this 996-tone RU can be continuous or non-contiguous; for example, the 996 subcarriers in this 996-tone RU can be composed of two non-contiguous subcarriers totaling 484 subcarriers.

For example, Figures 19 and 20 are schematic diagrams of a 100MHz channel partitioning. As shown in Figure 19, the first 20MHz of the 100MHz channel is punctured, and the consecutive 80MHz without puncturing corresponds to a 996-tone RU. Thus, the 100MHz channel includes a 996-tone RU, and the 996 subcarriers within this 996-tone RU are consecutive. Furthermore, in the 100MHz channel shown in Figure 19, the 996-tone RU is also defined across 80MHz, allowing for more flexible resource utilization.

As shown in Figure 20, the third 20MHz band within the 100MHz band is punctured. The combination of the first and second 20MHz bands corresponds to a 484 subcarrier, and the combination of the fourth and fifth 20MHz bands also corresponds to a 484 subcarrier. Two non-contiguous 484 subcarriers can form a non-contiguous virtual 996 subcarrier, i.e., a 996-tone RU. Furthermore, the subcarriers in the high-frequency band within the 996-tone RU are defined across 80MHz bands, allowing for more flexible resource utilization.

Specifically, for 100MHz configurations including a 484+484-tone MRU where the 484 subcarriers in the 484+484-tone MRU are discontinuous, and for 100MHz configurations including a 996-tone RU where the 996 subcarriers in the 996-tone RU are discontinuous, it is necessary to consider whether a DC component needs to be reserved in the discontinuous 484 subcarriers and the discontinuous 996 subcarriers. Since the DC component cannot be used for information transmission, two discontinuous 242 subcarriers cannot be combined into a 484-tone RU, nor can two discontinuous 484 subcarriers be combined into a 996-tone RU. In other words, when the DC component overlaps with a portion of the subcarriers in two discontinuous 242 subcarriers, the two discontinuous 242 subcarriers cannot be combined into a 484-tone RU. Similarly, when the DC component overlaps with a portion of the subcarriers in two discontinuous 484 subcarriers, the two discontinuous 484 subcarriers cannot be combined into a 996-tone RU. This method ensures that a 100MHz PPDU can successfully transmit information.

It can be seen that in non-OFDMA transmission, if 20MHz of 100MHz is punctured, the 100MHz channel includes 484+242+242-tone MRU, or the 100MHz channel includes 484+484-tone MRU, or the 100MHz channel includes 996-tone RU.

Scenario 1.13: 40MHz in 100MHz is punched.

In this scenario, 40MHz of the 100MHz channel is punctured, meaning that 40MHz of that 100MHz channel has been removed and cannot be used for data transmission. Therefore, 60MHz of that 100MHz channel is actually available for data transmission. Alternatively, the 40MHz puncturing of the 100MHz channel could mean that a 40MHz sub-channel within the 100MHz channel is punctured, for example, the 40MHz sub-channel within the 100MHz channel transmitting the first PPDU is punctured.

In this scenario, the first PPDU also includes a punch field indication information. This information indicates that 40MHz within the 100MHz band is punched. This 40MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the punched 40MHz band does not include the highest 20MHz band of the 100MHz band. Therefore, when 40MHz within the 100MHz band is punched, a consecutive 40MHz band from the first to the fourth 20MHz bands of the 100MHz band can be punched, and there are a total of three punch patterns.

One possible implementation is that the punch field indicates information as a punch field. Another possible implementation is that the first PPDU includes a U-SIG, where the U-SIG includes a punch field; the meaning of the punch field can be found in Table 5 above.

As can be seen from Table 5 above, when the value of the bandwidth field is set to 5, it means that the lowest 40MHz in the 100MHz channel is punctured; when the value of the bandwidth field is set to 6, it means that the second and third 20MHz in the 100MHz channel from low frequency to high frequency are punctured; when the value of the bandwidth field is set to 7, it means that the third and fourth 20MHz in the 100MHz channel from low frequency to high frequency are punctured.

In one optional implementation, when 40MHz of the 100MHz channel is punctured, one consecutive 40MHz that is not punctured corresponds to a 484-tone RU, and one 20MHz that is not punctured corresponds to a 242-tone RU, thus forming a 484+242-tone MRU. That is, the 100MHz channel can include 484+242-tone MRUs. For example, the 100MHz channel transmitting the first PPDU includes 484+242-tone MRUs. For instance, Figures 21 to 23 are schematic diagrams of a 100MHz channel partition. As shown in Figures 21 to 23, 40MHz of the 100MHz channel is punctured, and the 100MHz channel includes 484+242-tone MRUs, where the 484-tone RU is the RU corresponding to one consecutive 40MHz that is not punctured, and the 242-tone RU is the RU corresponding to one 20MHz that is not punctured. In addition, in the 100MHz channel shown in Figure 22, its 484-tone RU is defined across 80MHz, allowing for more flexible use of resources.

In another optional implementation, when 20MHz of the 100MHz channel is punctured, each 20MHz that is not punctured corresponds to a 242-tone RU, thus forming a 242+242+242-tone MRU. That is, the 100MHz channel can include 242+242+242-tone MRUs. For example, the 100MHz channel transmitting the first PPDU can include 242+242+242-tone MRUs. For instance, Figures 24 to 26 are schematic diagrams of a 100MHz channel partition. As shown in Figures 24 to 26, 40MHz of the 100MHz channel is punctured, and the 100MHz channel includes 242+242+242-tone MRUs, where each 242-tone RU is the RU corresponding to each 20MHz that is not punctured within the 100MHz channel.

One possible implementation is that when a 100MHz channel includes 242+242+242-tone MRUs, any two 242-tone MRUs can also form a 484-tone RU, including two 242-tone RUs located in different 80MHz ranges. For example, the 242-tone RU corresponding to the first 20MHz range in Figure 25 and the 242-tone RU corresponding to the fourth 20MHz range can form a non-contiguous 484 subcarrier, i.e., form a 484-tone RU, thus making the 100MHz channel include 484+242-tone MRUs, where the 484 subcarriers are non-contiguous.

It can be seen that in non-OFDMA transmission, if 40MHz of 100MHz is punctured, the 100MHz channel includes 484+242-tone MRU, or the 100MHz channel includes 242+242+242-tone MRU.

It should be noted that the puncture field shown in Table 5 above can indicate the allocation method of the 100MHz channel, or in other words, it can indicate the RU/MRU included in the 100MHz channel. Alternatively, the puncture mode indicated by the puncture field of the first PPDU can correspond to the RU/MRU included in the 100MHz channel.

Transmission mode 1.2: OFDMA transmission.

Compared to non-OFDMA transmission, in OFDMA transmission, the first device can allocate frequency domain resources to different users. Therefore, the first device can directly use the RU or MRU types already defined in the protocol without defining new RU or MRU types, reducing implementation complexity. Alternatively, the first device could redefine the RU or MRU types to allow for more flexible resource utilization and user scheduling.

Similar to non-OFDMA transmission, in OFDMA transmission, the 100MHz channel may or may not have puncturing. When puncturing is present in the 100MHz channel, either 20MHz or 40MHz of that 100MHz channel is punctured. The following describes the implementation of the 100MHz channel in OFDMA transmission mode for scenarios with no puncturing, 20MHz of that 100MHz channel being punctured, and 40MHz of that 100MHz channel being punctured:

Scenario 1.21: No punch holes exist at 100MHz.

In this scenario, the entire 100MHz band can be used for information transmission. The first device does not need to redefine a new RU or MRU; for example, it can directly allocate resources within 80MHz of the 100MHz band to one or more users, and allocate resources within the remaining 20MHz band to one or more other users.

In one optional implementation, when there is no puncturing in the 100MHz band, the 100MHz band may include one 484+242-tone MRU and two 242-tone RUs. For example, the 100MHz channel transmitting the first PPDU includes one 484+242-tone MRU and two 242-tone RUs. In this method, the first device defines the 484+242-tone MRU across 80MHz, allowing for more flexible resource utilization. For example, Figure 27 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 27, the 100MHz channel includes one 484+242-tone MRU and two 242-tone RUs, where the 484+242-tone MRU corresponding to the highest 60MHz in the 100MHz band is defined across 80MHz.

In another optional implementation, when there is no puncturing in the 100MHz channel, the 100MHz channel may include one 484-tone RU and three 242-tone RUs. For example, the 100MHz channel transmitting the first PPDU may include one 484-tone RU and three 242-tone RUs. For instance, Figure 28 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 28, the 100MHz channel includes one 484-tone RU and three 242-tone RUs.

In another optional implementation, when there is no puncturing in the 100MHz channel, the 100MHz channel may include five 242-tone RUs. For example, the 100MHz channel transmitting the first PPDU may include five 242-tone RUs. For example, Figure 29 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 29, the 100MHz channel includes five 242-tone RUs.

In another optional implementation, when there is no puncturing in the 100MHz channel, the 100MHz channel may include one 242-tone RU and two 484-tone RUs. For example, the 100MHz channel transmitting the first PPDU includes one 242-tone RU and two 484-tone RUs. For instance, Figure 30 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 30, the 100MHz channel includes one 242-tone RU and two 484-tone RUs.

In another optional implementation, when there is no puncturing in the 100MHz channel, the 100MHz channel may include a 242-tone RU and a 996-tone RU. For example, the 100MHz channel transmitting the first PPDU includes a 242-tone RU and a 996-tone RU. For instance, Figure 31 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 31, the 100MHz channel includes a 242-tone RU and a 996-tone RU. In addition, in the 100MHz channel shown in Figure 31, the 996-tone RU is defined across 80MHz, allowing for more flexible resource utilization.

In another optional implementation, when there is no puncturing in the 100MHz band, the 100MHz channel may include a 484+242-tone MRU and a 484-tone RU. For example, the 100MHz channel transmitting the first PPDU includes a 484+242-tone MRU and a 484-tone RU. For instance, Figure 32 is a schematic diagram of another 100MHz channel partitioning. As shown in Figure 32, the 100MHz channel includes a 484+242-tone MRU and a 484-tone RU. Furthermore, in the 100MHz channel shown in Figure 32, the 484-tone RU located in the high-frequency band is defined across 80MHz, allowing for more flexible resource utilization.

As can be seen, when there is no puncturing in the 100MHz band and no new RU or MRU type is defined, the first device can directly adopt the already defined RU or MRU type and divide the 100MHz channel according to the methods shown in Figures 28, 29, and 30 above, to reduce implementation complexity. Alternatively, when there is no puncturing in the 100MHz band, the first device can also define RUs across 80MHz as shown in Figures 27, 31, and 32, thus allowing for more flexible resource utilization.

Scenario 1.22: 20MHz of 100MHz is punched.

In this scenario, the first PPDU also includes a punch field indication information, which indicates that 20MHz of the 100MHz band has been punched, and the 20MHz band is located within the lowest 80MHz band of the 100MHz band. The meaning of the punch field indication information and the punching mode can be found in scenario 1.12 above, and will not be repeated here.

However, the specific format of the puncturing field indication information in this scenario differs from that in Scenario 1.12. For OFDMA transmission, the lowest 80MHz within 100MHz corresponds to a 4-bit puncturing indication, and the highest 20MHz corresponds to a 4-bit puncturing indication, with the 4-bit value corresponding to the highest 20MHz being 1111. Specifically, the 4-bit value corresponding to the lowest 80MHz within 100MHz indicates the puncturing status of 20MHz within that lowest 80MHz, while the 1111 value corresponding to the highest 20MHz indicates that the highest 20MHz is not punctured. In other words, for OFDMA transmission, for the first PPDU at 100MHz, there are two 4-bit puncturing indication messages: one corresponding to the lowest 80MHz within 100MHz, indicating the puncturing status of 20MHz within that lowest 80MHz; and the other bit set to 1111, indicating that the highest 20MHz within 100MHz is not punctured.

In OFDMA transmission, when the puncture field indicator information is a puncture field, the meaning of the puncture field can be found in Table 6 below:

Table 6

In Table 6, the value -1 represents a 4-bit segment corresponding to the lowest 80MHz within the 100MHz range, and the value -2 represents a 4-bit segment corresponding to the highest 20MHz within the 100MHz range. The value of the value -1 indicates the puncturing pattern of the 20MHz segment within the lowest 80MHz range. For example, a value of 0111 indicates that the lowest 20MHz segment within that 80MHz range is punctured. A value of 1111 for the value -2 indicates that the highest 20MHz segment within the 100MHz range is not punctured, thus ensuring the transmission resources of the 100MHz range.

Additionally, when 20MHz of the 100MHz band is punctured, the channel allocation method for the 100MHz band can be found in Scenario 1.12 above. For example, when 20MHz of the 100MHz band is punctured, the 100MHz channel includes 484+242+242-tone MRUs, such as the 100MHz channel transmitting the first PPDU including 484+242+242-tone MRUs. As another example, when 20MHz of the 100MHz band is punctured, the 100MHz channel includes 484+484-tone MRUs, such as the 100MHz channel transmitting the first PPDU including 484+484-tone MRUs, where the two 484 subcarriers in the 484+484-tone MRU can be consecutive or non-consecutive. For example, when 20MHz of 100MHz is punched, the 100MHz channel includes a 996-tone RU. For instance, the 100MHz channel transmitting the first PPDU may include a 996-tone RU, where the 996 subcarriers in the 996-tone RU may be continuous or discontinuous.

Scenario 1.23: 40MHz in 100MHz is punched.

In this scenario, the first PPDU also includes a punch field indication information, which indicates that 40MHz of the 100MHz band has been punched, and the 40MHz band is located within the lowest 80MHz band of the 100MHz band. The meaning of the punch field indication information and the punching mode can be found in scenario 1.13 above, and will not be repeated here.

However, the specific format of the puncturing field indication information in this method differs from that in scenario 1.13. For OFDMA transmission, the lowest 80MHz within 100MHz corresponds to a 4-bit puncturing indication, and the highest 20MHz corresponds to a 4-bit puncturing indication, with the 4-bit value corresponding to the highest 20MHz being 1111. Specifically, the 4-bit value corresponding to the lowest 80MHz within 100MHz indicates the puncturing status of 40MHz within that lowest 80MHz, while the 1111 value corresponding to the highest 20MHz indicates that the highest 20MHz is not punctured. In other words, for OFDMA transmission, for the first PPDU at 100MHz, there are two 4-bit puncturing indications: one corresponding to the lowest 80MHz within 100MHz, indicating the puncturing status of 40MHz within that lowest 80MHz; and the other bit set to 1111, indicating that the highest 20MHz within 100MHz is not punctured.

In OFDMA transmission, when the puncturing field indication information is a puncturing field, the various cases in which the puncturing field indicates that 40MHz of 100MHz is punctured can be seen in Table 6 above, and will not be repeated here.

Additionally, when 40MHz of the 100MHz band is punctured, the channel allocation method for the 100MHz band can be found in Scenario 1.13 above. For example, when 40MHz of the 100MHz band is punctured, the 100MHz channel can include 484+242-tone MRUs, such as the 100MHz channel transmitting the first PPDU. As another example, when 40MHz of the 100MHz band is punctured, the 100MHz channel can include 242+242+242-tone MRUs, such as the 100MHz channel transmitting the first PPDU.

It should be noted that the punched field shown in Table 6 above can indicate the division method of the 100MHz channel, or in other words, it can indicate the RU/MRU included in the 100MHz channel.

Furthermore, for OFDMA transmission, if the first PPDU includes a UHR-SIG field, a Resource Unit Allocation (RU Allocation) field will further exist in the common part of the UHR-SIG field. This RU Allocation field is used to allocate RUs or MRUs to users and to indicate the number of users corresponding to the allocated RUs or MRUs. Generally, there is one RU Allocation field for every 242-tone RU range. Thus, for a first PPDU occupying 100MHz, there are a total of 5 RU Allocation fields (labeled from low to high frequency as RU Allocation#1 to RU Allocation#5). Furthermore, within an 80MHz frequency sub-block, two content channels (CCs) are typically defined, carrying different content on different 20MHz sub-channels to improve transmission efficiency.

For 100MHz OFDMA transmission, or Non-OFDMA MU-MIMO transmission, each CC is carried within a 20MHz band. Within the lowest 80MHz band of 100MHz, there is a repeating pattern of CC1, CC2, CC1, CC2; within the highest 20MHz band of 100MHz, there exists CC1, the content of which can differ from the content of CC1 within the lowest 80MHz band, and therefore can also be designated as CC3.

In other words, the 100MHz channel transmitting the first PPDU includes a first content channel and a second content channel in the lower 80MHz, and a third content channel in the upper 20MHz. One possible implementation is that the first PPDU includes a UHR-SIG, where the UHR-SIG includes the first and second content channels in the lower 80MHz, and the third content channel in the upper 20MHz.

In one optional implementation, the first content channel and the third content channel each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields. The resource unit allocation fields carried by the first content channel, the second content channel, and the third content channel are used to indicate the allocation of RU or MRU.

For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3. CC1 and CC2 are the CCs included in the lower 80MHz of a 100MHz channel, and CC3 is the CC included in the upper 20MHz of a 100MHz channel. Figure 33 is a schematic diagram of resource unit allocation information. As shown in Figure 33, UHR-SIG includes CC1, CC2, and CC3, and within the lowest 80MHz of the 100MHz channel, it is a repeating pattern of CC1, CC2, CC1, CC2. CC1 and CC2 carry RU Allocation#1, RU Allocation#2, RU Allocation#3, RU Allocation#4, and RU Allocation#5 sequentially from low to high frequency. Therefore, CC1 carries RU Allocation#1, RU Allocation#3, and RU Allocation#5, and CC2 carries RU Allocation#2 and RU Allocation#4. The RU Allocation carried by CC3 is the same as the RU Allocation carried by CC1, i.e., CC3 carries RU Allocation#1, RU Allocation#3, and RU Allocation#5. Each RU Allocation carried by CC1, CC2, and CC3 is used to indicate the allocation of RUs or MRUs. CC1 and CC3 need to indicate consistent RU or MRU allocations, including the size and location of the RUs or MRUs. One possible implementation is that the number of users indicated by each RU Allocation carried by CC3 may not be the same as the number of users indicated by each RU Allocation carried by CC1; for example, the number of users indicated by RU Allocation#1 carried by CC3 may not be the same as the number of users indicated by RU Allocation#1 carried by CC1. Another possible implementation is that the number of users indicated by each RU Allocation carried by CC3 may be the same as the number of users indicated by each RU Allocation carried by CC1; for example, the number of users indicated by RU Allocation#1 carried by CC3 may be the same as the number of users indicated by RU Allocation#1 carried by CC1. In this method, CC1 and CC3 are the same.

As shown in Figure 33, each CC also carries a cyclic redundancy code (CRC) and a tail. The CRC is used to verify whether the bits of the coded block have been transmitted correctly. The tail is the end of the code; setting the tail to 0 terminates the grid of the convolutional decoder. The end of the tail in each CC can mark the end of a field, and this field can be called the common field of the CC. Additionally, each CC also carries a U-SIG overflow field, which is used to carry common information that U-SIG cannot carry.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. Furthermore, the first and third common coding blocks each carry three resource unit allocation fields, while the second common coding block carries two resource unit allocation fields. Alternatively, if the first and third content channels each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields, then the common fields of the first, second, and third content channels are each located in a single common coding block. This approach saves on CRC and Tail overhead.

For example, Figures 34 to 36 are schematic diagrams of resource unit allocation information. As shown in Figure 34, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 are located in common coding block 11. As shown in Figure 35, the common fields corresponding to RU Allocation#2 and RU Allocation#4 carried by CC2 are located in common coding block 21. As shown in Figure 36, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC3 are located in common coding block 31.

Additionally, Figures 34 to 36 also include user coding blocks, such as user coding block 11. This user coding block carries a user identifier, and the user identifier corresponds to the RU or MRU allocation indicated by the RU Allocation carried by the common coding block. For example, in Figure 34, the RU or MRU allocations indicated by RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by the common coding block 11 correspond to the user identifier carried by user coding block 11. Alternatively, it can be understood that the RU or MRU allocations indicated by RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by the common coding block 11 are allocated to the user corresponding to the user identifier carried by user coding block 11. Similarly, the user coding blocks and common coding blocks in the following resource unit allocation information diagrams have the same understanding and will not be elaborated further.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third common coding block, and the common fields of the third content channel are located in the fourth and fifth common coding blocks. The first, third, and fourth common coding blocks each carry two resource unit allocation fields, while the second and fifth common coding blocks each carry one resource unit allocation field. Alternatively, if the first and third content channels each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields, then the common fields of the first and third content channels are located in two separate common coding blocks, and the common fields of the second content channel are located in one common coding block.

For example, Figures 37 to 39 are schematic diagrams of resource unit allocation information. As shown in Figure 37, the common fields corresponding to RU Allocation#1 and RU Allocation#3 carried by CC1 are located in common coding block 11, and the common field corresponding to RU Allocation#5 carried by CC1 is located in common coding block 12. As shown in Figure 38, the common fields corresponding to RU Allocation#2 and RU Allocation#4 carried by CC2 are located in common coding block 21. As shown in Figure 39, the common fields corresponding to RU Allocation#1 and RU Allocation#3 carried by CC3 are located in common coding block 31, and the common field corresponding to RU Allocation#5 carried by CC1 is located in common coding block 32.

As can be seen, the first content channel and the third content channel each carry three resource unit allocation fields, and the second content channel carries two resource unit allocation fields. When the resource unit allocation fields carried by the first content channel, the second content channel, and the third content channel are used to indicate the allocation of RU or MRU, the common fields of the first content channel, the second content channel, and the third content channel are each located in one common coding block, or the common fields of the first content channel and the third content channel are each located in two common coding blocks, and the common field of the second content channel is located in one common coding block.

In another optional implementation, the first content channel, the second content channel, and the third content channel each carry three resource unit allocation fields. Specifically, the three resource unit allocation fields carried by the first and third content channels are used to indicate the allocation of RUs or MRUs; of the three resource unit allocation fields carried by the second content channel, two resource unit allocation fields are used to indicate the allocation of RUs or MRUs, and one resource unit allocation field is a reserved field or used to indicate punching information or reserved information. In one possible implementation, the one resource unit allocation field carried by the second content channel can be replaced with a reserved field.

The first, second, and third content channels all carry three resource unit allocation fields, which ensures that the length of common fields in different content channels is equal, which is beneficial for the receiving end (such as the second device) to decode and parse.

For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3. CC1 and CC2 are the CCs included in the lower 80MHz of the 100MHz channel transmitting the first PPDU, and CC3 is the CC included in the upper 20MHz of the 100MHz channel. Figure 40 is a schematic diagram of another type of resource unit allocation information. As shown in Figure 40, CC1 and CC3 both carry RU Allocation#1, RU Allocation#3, and RU Allocation#5, while CC2 carries RU Allocation#2, RU Allocation#4, and RU Allocation#6. The RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 and CC3, and the RU Allocation#2 and RU Allocation#4 carried by CC2, are used to indicate the allocation of RUs or MRUs. The RU Allocation#6 carried by CC2 is used to indicate puncturing information or reservation information. One possible implementation is that the RU Allocation#6 carried by CC2 can be replaced with a reserved field, that is, the RU Allocation#4 carried by CC2 is followed by a reserved field, not a RU Allocation field.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. The first, second, and third common coding blocks each carry three resource unit allocation fields. Alternatively, if the first, second, and third content channels each carry three resource unit allocation fields, then the common fields of the first, second, and third content channels are each located in a single common coding block.

For example, Figures 41 to 43 are schematic diagrams of resource unit allocation information. As shown in Figure 41, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 are located in common coding block 11. As shown in Figure 42, the common fields corresponding to RU Allocation#2, RU Allocation#4, and RU Allocation#6 or reserved fields carried by CC2 are located in common coding block 21. As shown in Figure 43, the common fields corresponding to RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC3 are located in common coding block 31.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. Specifically, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one resource unit allocation field; or, the first, third, and fifth common coding blocks each carry two resource unit allocation fields, and the second, fourth, and sixth common coding blocks each carry one reserved field. Alternatively, if the first, second, and third content channels each carry three resource unit allocation fields, the common fields of the first, second, and third content channels are each located in two common coding blocks.

For example, Figures 44 to 46 are schematic diagrams of resource unit allocation information. As shown in Figure 44, the common fields corresponding to RU Allocation#1 and RU Allocation#3 carried by CC1 are located in common coding block 11, and the common field corresponding to RU Allocation#5 carried by CC1 is located in common coding block 12. As shown in Figure 45, the common fields corresponding to RU Allocation#2 and RU Allocation#4 carried by CC2 are located in common coding block 21, and the common fields corresponding to RU Allocation#6 or reserved fields carried by CC2 are located in common coding block 22. As shown in Figure 46, the common fields corresponding to RU Allocation#1 and RU Allocation#3 carried by CC3 are located in common coding block 31, and the common field corresponding to RU Allocation#5 carried by CC3 is located in common coding block 32.

As can be seen, when the first content channel, the second content channel, and the third content channel each carry three resource unit allocation fields, the common fields of the first content channel, the common fields of the second content channel, and the common fields of the third content channel are each located in one common coding block, or the common fields of the first content channel, the common fields of the second content channel, and the common fields of the third content channel are each located in two common coding blocks.

S102. The first device transmits the first PPDU using a 100MHz channel.

S103. The second device receives the first PPDU.

S104. The second device analyzes the first PPDU.

The second device parses the first PPDU, including: reading the bandwidth field indication information of the first PPDU, and obtaining that the bandwidth occupied by the first PPDU is 100MHz through the bandwidth field indication information. One possible implementation is that the second device reads the bandwidth field in the U-SIG of the first PPDU, and obtains that the bandwidth occupied by the first PPDU is 100MHz through the bandwidth field.

In one possible implementation, the second device further reads the puncture field indication information of the first PPDU. Through this information, it obtains the puncture status of the 100MHz channel transmitting the first PPDU. Based on this 100MHz puncture status, it can then obtain the channel carrying the data information and retrieve the data information from that channel. Alternatively, the second device reads the puncture field in the U-SIG of the first PPDU. Through this field, it obtains the puncture status of the 100MHz channel transmitting the first PPDU, thereby retrieving data information from the unpunctured channel.

In one optional implementation, 100MHz belongs to the unlicensed frequency band of 5735MHz to 5835MHz. For example, the 100MHz used to transmit the first PPDU belongs to the unlicensed frequency band of 5735MHz to 5835MHz. In this way, the first device can make full use of the 100MHz corresponding to the unlicensed frequency band of 5735MHz to 5835MHz to transmit data, thereby maximizing the spectrum utilization of 5.8GHz, improving spectrum utilization and system throughput, and reducing latency.

Furthermore, the spectrum in the unlicensed UNII-2A band requires dynamic frequency selection (DFS) and transmit power control (TPC) to detect signals such as weather radar, which is complex and prone to false alarms. Therefore, it is difficult to use spectrum greater than 80MHz in the 5.1GHz band. When 100MHz falls within the unlicensed band of 5735MHz to 5835MHz, the addition of a 100MHz channel in the UNII-3 section makes it easier to use spectrum greater than 80MHz.

One possible implementation is to use a licensed frequency band, such as the 100MHz band used to transmit the first PPDU. This approach is suitable for environments where there is a relatively available bandwidth of 100MHz, allowing the first device to fully utilize this 100MHz for data transmission, thus improving spectrum utilization.

One possible implementation is that, in addition to sending a 100MHz PPDU to the second device, the first device can also send a 160MHz PPDU to the second device. That is, the first device can combine multi-link operation (MLO) to utilize 160MHz of 5.1GHz for transmission and 100MHz of 5.8GHz for transmission, thereby maximizing the spectrum utilization of 5GHz.

As can be seen, in this embodiment of the application, the first device generates a 100MHz first PPDU and transmits the first PPDU to the second device using a 100MHz channel, thereby achieving 100MHz data transmission. Compared with the first device using a PPDU with a predefined protocol for information transmission, this method can improve spectrum utilization.

This application also proposes a communication method 200, and Figure 47 is an interactive schematic diagram of the communication method 200. The communication method 200 is also described from the perspective of the interaction between a first device and a second device. The communication method 200 includes, but is not limited to, the following steps:

S201. The first device generates a first PPDU, which includes bandwidth field indication information and puncture field indication information. The bandwidth field indication information is used to indicate that the bandwidth of the first PPDU is 160MHz, and the puncture field indication information is used to indicate that the highest 60MHz of the 160MHz is punctured.

One possible implementation is that the first PPDU includes general signaling field indication information, which includes bandwidth field indication information and puncturing field indication information. Furthermore, the general signaling field indication information can be a general signaling field, and the bandwidth field indication information can be information used to indicate bandwidth, such as a bandwidth field indicating that the bandwidth of the first PPDU is 160MHz; the puncturing field indication information can be information used to indicate the puncturing mode, such as a puncturing field indicating that the puncturing field is used to indicate the first PPDU.

In one optional implementation, the first PPDU includes a U-SIG, which includes a bandwidth field and a puncturing field. The bandwidth field in the U-SIG has a value of 3, indicating that the bandwidth of the first PPDU is 160MHz. Additionally, the puncturing field in the U-SIG indicates that up to 60MHz of the 160MHz bandwidth is punctured, so the actual bandwidth occupied by the first PPDU is 100MHz.

As can be seen, the first device can indicate that the bandwidth of the first PPDU is 160MHz through the bandwidth field in U-SIG, and indicate that the highest 60MHz of that 160MHz is punched through the punching field in U-SIG, so that the bandwidth actually occupied by the first PPDU is 100MHz.

One possible implementation is that the puncturing field indication information does not indicate that the highest 60MHz in 160MHz is punctured, but is used to indicate that the lowest 60MHz in 160MHz is punctured, so that the bandwidth actually occupied by the first PPDU is 100MHz.

In one optional implementation, the first PPDU is a UHR PPDU, which can be referred to in S101 above and will not be repeated here. Another possible implementation is that the first PPDU can be a PPDU from a standard later than 802.11bn; this application does not limit this implementation. For ease of explanation, the following description uses a UHR PPDU as the first PPDU.

Furthermore, the first PPDU's transmission modes include non-OFDMA transmission and OFDMA transmission. The following describes the implementation methods for the 100MHz channel for both non-OFDMA and OFDMA transmission modes:

Transmission mode 2.1: non-OFDMA transmission.

In Non-OFDMA transmission, the MRU in the 100MHz channel actually occupied by the first PPDU needs to be redefined. Furthermore, the 100MHz channel actually occupied by the first PPDU may or may not have punctured bandwidth. When the 100MHz channel actually occupied by the first PPDU has punctured bandwidth, 20MHz or 40MHz of that 100MHz can be punctured. Therefore, the following describes the implementation methods for the 100MHz channel actually occupied by the first PPDU in scenarios where there is no punctured bandwidth, 20MHz of that 100MHz is punctured, and 40MHz of that 100MHz is punctured:

Scenario 2.11: The 100MHz actually occupied by the first PPDU does not have any punch holes.

The 100MHz actually occupied by the first PPDU has no punch holes, indicating that the 100MHz actually occupied by the first PPDU can be used for data transmission.

In this scenario, the implementation method for the 100MHz channel actually occupied by the first PPDU can be found in scenario 1.11 of the communication method 100 described above, and will not be repeated here. For example, 80MHz of the 100MHz actually occupied by the first PPDU can correspond to a 996-tone RU, and the maximum 20MHz can correspond to a 242-tone RU, so the channel for transmitting the first PPDU can include 996+242-tone MRU.

It should be noted that the 160MHz channel defined in the current protocol does not include the 996+242-tone MRU case. In other words, the 996+242-tone MRU format is a newly defined MRU format in this application embodiment.

Scenario 2.12: 20MHz of the 100MHz actually occupied by the first PPDU is punched.

In this case, 20MHz of the 100MHz actually occupied by the first PPDU is punched, indicating that 80MHz of the 100MHz actually occupied by the first PPDU can be used for data transmission.

In this scenario, the puncturing field indication information of the first PPDU is also used to indicate that 20MHz of the 100MHz band is punctured. This 20MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the punctured 20MHz band is not the highest 20MHz band of the 100MHz band. Therefore, when 20MHz of the 100MHz band actually occupied by the first PPDU is punctured, the first to fourth 20MHz bands of that 100MHz band can be punctured, resulting in a total of four puncturing modes.

One possible implementation is that the punch field indicates the punch field information, and the meaning of the punch field can be found in Table 7 below:

Table 7

As shown in Table 7, when the value of the "punch" field is 0, it means that the highest 60MHz in the 160MHz range has been punched, and the lowest 100MHz has no punches. When the value of the "punch" field is 1 to 4, it means that the highest 60MHz in the 160MHz range has been punched, and the second 20MHz in the lowest 100MHz range has been punched. For example, when the value of the "punch" field is 2, it means that the highest 60MHz in the 160MHz range has been punched, and the second 20MHz in the lowest 100MHz range has been punched.

In addition, when 20MHz of the 100MHz actually occupied by the first PPDU is punched, the channel allocation method of the actually occupied 100MHz can be referred to the channel allocation method of 100MHz in scenario 1.12 of the above-mentioned communication method 100, or the allocation method of the 100MHz channel for transmitting the first PPDU can be referred to the channel allocation method of 100MHz in scenario 1.12 of the above-mentioned communication method 100, and will not be repeated here.

For example, when 20MHz of the 100MHz channel actually occupied by the first PPDU is punctured, that 100MHz includes 484+242+242-tone MRUs. As another example, when 20MHz of the 100MHz channel actually occupied by the first PPDU is punctured, that 100MHz includes 484+484-tone MRUs. As yet another example, when 20MHz of the 100MHz channel actually occupied by the first PPDU is punctured, that 100MHz includes 996-tone RUs.

Scenario 2.13: 40MHz of the 100MHz actually occupied by the first PPDU is punched.

In this case, 40MHz of the 100MHz actually occupied by the first PPDU is punched, indicating that 60MHz of the 100MHz actually occupied by the first PPDU can be used for data transmission.

In this scenario, the puncturing field indication information of the first PPDU is also used to indicate that 40MHz of the 100MHz band is punctured. This 40MHz band is located within the lowest 80MHz band of the 100MHz band, or in other words, the punctured 40MHz band does not include the highest 20MHz band of the 100MHz band. Therefore, when 40MHz of the 100MHz band is punctured, 40MHz bands from the first to fourth 20MHz bands of the 100MHz band can be punctured, resulting in three puncturing patterns, the specific patterns of which can be found in Table 7 above. For example, when the puncturing field value is set to 5, it indicates that the highest 60MHz band of the 160MHz band is punctured, and the lowest 40MHz band of the lowest 100MHz band of the 160MHz band is punctured.

In addition, when 40MHz of the 100MHz actually occupied by the first PPDU is punched, the channel allocation method of the actually occupied 100MHz can be referred to the channel allocation method of 100MHz in scenario 1.13 of the above-mentioned communication method 100, or the allocation method of the 100MHz channel for transmitting the first PPDU can be referred to the channel allocation method of 100MHz in scenario 1.13 of the above-mentioned communication method 100, and will not be repeated here.

For example, if 40MHz of the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel can include a 484+242-tone MRU. As another example, if 40MHz of the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel can include a 242+242+242-tone MRU.

Transmission mode 2.2: OFDMA transmission.

In OFDMA transmission mode, the first device can directly adopt the already defined RU or MRU type without defining a new RU or MRU type, thus reducing implementation complexity. Alternatively, the first device can redefine the RU or MRU type to allow for more flexible resource utilization and user scheduling.

Similar to non-OFDMA transmission, for OFDMA transmission, the following scenarios are further divided into three scenarios: no puncturing in the 100MHz actually occupied by the first PPDU, 20MHz of the 100MHz actually occupied by the first PPDU is punctured, and 40MHz of the 100MHz actually occupied by the first PPDU is punctured. The implementation methods for the 100MHz channel actually occupied by the first PPDU are described below:

Scenario 2.21: The 100MHz actually occupied by the first PPDU does not have any vias.

When there is no puncturing in the 100MHz actually occupied by the first PPDU, the first device may choose not to redefine a new RU or MRU, or it may redefine a new RU or MRU. In this method, the channel allocation method for the 100MHz actually occupied by the first PPDU can be found in the 100MHz channel allocation method in scenario 1.21 of the above communication method 100, and will not be repeated here.

For example, if there are no puncturing ROMs in the 100MHz channel actually occupied by the first PPDU, the 100MHz channel actually occupied by the first PPDU includes one 484+242-tone MRU and two 242-tone RUs. As another example, if there are no puncturing ROMs in the 100MHz channel actually occupied by the first PPDU, the 100MHz channel actually occupied by the first PPDU includes one 484-tone RU and three 242-tone RUs. As yet another example, if there are no puncturing ROMs in the 100MHz channel actually occupied by the first PPDU, the 100MHz channel actually occupied by the first PPDU includes five 242-tone RUs. As yet another example, if there are no puncturing ROMs in the 100MHz channel actually occupied by the first PPDU, the 100MHz channel actually occupied by the first PPDU may include one 242-tone RU and two 484-tone RUs.

Scenario 2.22: 20MHz of the 100MHz actually occupied by the first PPDU is punched.

In this scenario, the punch field indication information is also used to indicate that 20MHz within the 100MHz band has been punched, and this 20MHz band is located within the lowest 80MHz band of the 100MHz band. The meaning of the punch field indication information and the punching mode can be found in scenario 1.12 above, and will not be repeated here.

However, the specific format of the puncturing field indication information in this method differs from that in Scenario 1.12. For OFDMA transmission, the lowest 80MHz within the 160MHz band corresponds to a 4-bit puncturing indication, and the highest 80MHz corresponds to a 4-bit puncturing indication, with the 4-bit corresponding to the highest 80MHz being 1000. Specifically, the 4-bit corresponding to the lowest 80MHz within the 160MHz band indicates the puncturing status of 20MHz within that band, while the 1000 corresponding to the highest 80MHz indicates that the highest 60MHz within that band is punctured and the lowest 20MHz is not. In other words, for OFDMA transmission, for the first PPDU of 160MHz, there are two 4-bit puncturing indication messages. One 4-bit puncturing indication message corresponds to the lowest 80MHz in 160MHz and is used to indicate the puncturing status of 20MHz in the lowest 80MHz. The other bit is set to 1000 and is used to indicate that the highest 60MHz in the highest 80MHz in 160MHz is punctured and the lowest 20MHz is not punctured.

In OFDMA transmission, when the puncture field indicator information of the first PPDU is a puncture field, the meaning of the puncture field can be found in Table 8 below:

Table 8

In Table 8, the value -1 represents a 4-bit segment corresponding to the lowest 80MHz within the 160MHz range, and the value -2 represents a 4-bit segment corresponding to the highest 80MHz within the 160MHz range. Specifically, the value of the value -1 represents the puncturing pattern of 20MHz within the lowest 80MHz range. For example, a value of 0111 indicates that the lowest 20MHz within that lowest 80MHz range is punctured. A value of 1000 for the value -2 indicates that the highest 60MHz within the 160MHz range is punctured while the lowest 20MHz is not, thus ensuring that the first PPDU actually occupies 100MHz of bandwidth.

Furthermore, when 20MHz of the 100MHz actually occupied by the first PPDU is punctured, the channel allocation method for the 100MHz actually occupied by the first PPDU can be found in the 100MHz channel allocation method in scenario 1.22 of the aforementioned communication method 100, and will not be repeated here. For example, when 20MHz of the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes 484+242+242-tone MRUs. As another example, when 20MHz of the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes 484+484-tone MRUs, where the two 484 subcarriers in the 484+484-tone MRUs are either consecutive or non-consecutive. As yet another example, when 20MHz of the 100MHz actually occupied by the first PPDU is punctured, the 100MHz channel includes 996-tone RUs, where the 996 subcarriers in the 996-tone RUs are either consecutive or non-consecutive.

Scenario 2.23: 40MHz of the 100MHz actually occupied by the first PPDU is punched.

In this scenario, the punch field indication information is also used to indicate that 40MHz of the 100MHz actually occupied by the first PPDU has been punched, and the 40MHz is located within the lowest 80MHz of the 100MHz. The meaning of the punch field indication information and the punching mode can be found in Scenario 1.23 above, and will not be repeated here.

However, the specific format of the puncturing field indication information in this method differs from that in scenario 1.13. For OFDMA transmission, the lowest 80MHz of the first PPDU corresponds to a 4-bit puncturing indication, and the highest 60MHz corresponds to a 4-bit puncturing indication, with the 4-bit corresponding to the highest 60MHz being 1000. Specifically, the 4-bit corresponding to the lowest 80MHz within the 160MHz range indicates the puncturing status of 40MHz within that lowest 80MHz range, while the 1000 corresponding to the highest 80MHz indicates that the highest 60MHz within that highest 80MHz range is punctured and the lowest 20MHz is not punctured. In other words, for OFDMA transmission, for the first PPDU of 160MHz, there are two 4-bit puncturing indication messages. One 4-bit puncturing indication message corresponds to the lowest 80MHz in 160MHz and is used to indicate the puncturing status of 40MHz in the lowest 80MHz. The other bit is set to 1000 and is used to indicate that the highest 60MHz in the highest 80MHz in 160MHz is punctured and the lowest 20MHz is not punctured.

In OFDMA transmission, when the puncturing field indication information is a puncturing field, the meaning of the puncturing field indicating that 40MHz of the 100MHz actually occupied by the first PPDU is punctured can be found in Table 8 above, and will not be repeated here.

Additionally, when 40MHz of the 100MHz actually occupied by the first PPDU is punctured, the channel allocation method for that 100MHz can be found in the 100MHz channel allocation method in Scenario 1.13 above. For example, when 40MHz of the 100MHz actually occupied by the first PPDU is punctured, that 100MHz channel includes 484+242-tone MRUs. As another example, when 40MHz of the 100MHz actually occupied by the first PPDU is punctured, that 100MHz channel includes 242+242+242-tone MRUs.

Furthermore, for OFDMA transmission, if the first PPDU includes a UHR-SIG field, the common portion of the UHR-SIG field contains an RU Allocation field for user RU or MRU allocation, and an indication of the number of users corresponding to the allocated RU or MRU. Thus, for a 160MHz first PPDU, there is one RU Allocation field for every 20MHz within the 160MHz, resulting in a total of eight RU Allocation fields (labeled RU Allocation#1 to RU Allocation#8 from low to high frequency). Further, two content channels (CCs) are typically defined, carrying different content on different 20MHz sub-channels to improve transmission efficiency.

For OFDMA transmission of the first PPDU at 160MHz, or MU-MIMO transmission of Non-OFDMA, each CC is carried within a 20MHz band. Within the lowest 80MHz band of 160MHz, there is a repeating pattern of CC1, CC2, CC1, CC2; within the highest 80MHz band of 160MHz, there is CC1, the content of which may differ from the content of CC1 within the highest 80MHz band, and therefore it can also be designated as CC3.

In other words, the 100MHz channel used to transmit the first PPDU in the 160MHz band includes a first content channel and a second content channel in the lower 80MHz band, and a third content channel in the upper 20MHz band. One possible implementation is that the first PPDU includes a UHR-SIG, where the UHR-SIG includes the first and second content channels in the lower 80MHz band, and the third content channel in the upper 20MHz band.

In one optional implementation, the first content channel, the second content channel, and the third content channel each carry four resource unit allocation fields. Specifically, of the four resource unit allocation fields carried by the first and third content channels, three are used to indicate the allocation of RUs or MRUs, and one is a reserved field, or used to indicate punching information or reserved information. Of the four resource unit allocation fields carried by the second content channel, two are used to indicate the allocation of RUs or MRUs, and two are reserved fields, or used to indicate punching information or reserved information.

One possible implementation is that the first content channel and the third content channel carry three resource unit allocation fields and one reservation field, respectively, and the second content channel carries two resource unit allocation fields and two reservation fields. Each resource unit allocation field is used to indicate the allocation of RU or MRU.

For example, the first content channel is CC1, the second content channel is CC2, and the third content channel is CC3. CC1 and CC2 are the CCs included in the lower 80MHz of the 100MHz channel actually occupied by the first PPDU, and CC3 is the CCs included in the upper 20MHz of the 100MHz channel actually occupied by the first PPDU. Figure 48 is a schematic diagram of another type of resource unit allocation information. As shown in Figure 48, CC1 carries RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7; CC2 carries RU Allocation#2, RU Allocation#4, RU Allocation#6, and RU Allocation#8; and CC3 carries RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7. Specifically, RU Allocation#1, RU Allocation#3, and RU Allocation#5 carried by CC1 and CC3 are used to indicate the allocation of RU or MRU. RU Allocation#7 carried by CC1 and CC3 is used to indicate punching information or reservation information. Alternatively, CC1 and CC3 may carry a reservation field instead of RU Allocation#7. RU Allocation#2 and RU Allocation#4 carried by CC2 are used to indicate the allocation of RU or MRU. RU Allocation#6 and RU Allocation#8 carried by CC2 are used to indicate punching information or reservation information. Alternatively, CC2 may carry two reservation fields instead of RU Allocation#6 and RU Allocation#8.

One possible implementation is that the common fields of the first content channel are located in the first common coding block, the common fields of the second content channel are located in the second common coding block, and the common fields of the third content channel are located in the third common coding block. The first, second, and third common coding blocks each carry four resource unit allocation fields. Alternatively, if the first, second, and third content channels each carry four resource unit allocation fields, then the common fields of the first, second, and third content channels are each located in a single common coding block.

For example, Figures 49 to 51 are schematic diagrams of resource unit allocation information. As shown in Figure 49, the common fields corresponding to RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7 carried by CC1 are located in common coding block 11. As shown in Figure 50, the common fields corresponding to RU Allocation#2, RU Allocation#4, RU Allocation#6, and RU Allocation#8 carried by CC2 are located in common coding block 21. As shown in Figure 51, the common fields corresponding to RU Allocation#1, RU Allocation#3, RU Allocation#5, and RU Allocation#7 carried by CC3 are located in common coding block 31.

One possible implementation is that the common fields of the first content channel are located in the first and second common coding blocks, the common fields of the second content channel are located in the third and fourth common coding blocks, and the common fields of the third content channel are located in the fifth and sixth common coding blocks. The first to sixth common coding blocks each carry two resource unit allocation fields. Alternatively, if the first, second, and third content channels each carry four resource unit allocation fields, the common fields of the first, second, and third content channels are each located in two common coding blocks.

For example, Figures 52 to 54 are schematic diagrams of resource unit allocation information. As shown in Figure 52, the common fields corresponding to RU Allocation#1 and RU Allocation#3 on CC1 are located in common coding block 11, and the common fields corresponding to RU Allocation#5 and RU Allocation#7 are located in common coding block 12. As shown in Figure 53, the common fields corresponding to RU Allocation#2 and RU Allocation#4 on CC2 are located in common coding block 21, and the common fields corresponding to RU Allocation#6 and RU Allocation#8 are located in common coding block 22. As shown in Figure 54, the common fields corresponding to RU Allocation#1 and RU Allocation#3 on CC3 are located in common coding block 31, and the common fields corresponding to RU Allocation#5 and RU Allocation#7 are located in common coding block 32.

It can be seen that when the first content channel, the second content channel, and the third content channel carry four resource unit allocation fields respectively, the common fields of the first content channel, the common fields of the second content channel, and the common fields of the third content channel are located in one common coding block, or the common fields of the first content channel, the common fields of the second content channel, and the common fields of the third content channel are located in two common coding blocks respectively.

S202. The first device uses the remaining 100MHz channel after punching the highest 60MHz of the 160MHz channel to transmit the first PPDU.

S203. The second device receives the first PPDU.

S204. Second device analyzes the first PPDU.

The second device parses the first PPDU, including: reading the bandwidth field indication information and the puncturing field indication information of the first PPDU, obtaining the bandwidth of the first PPDU as 160MHz through the bandwidth field indication information, and obtaining the highest 60MHz of the 160MHz through the puncturing field indication information, thereby determining that the actual bandwidth occupied by the first PPDU is 100MHz.

In one possible implementation, the second device further obtains the puncturing status of the 100MHz channel actually occupied by the first PPDU by reading the puncturing field indication information. Based on this puncturing status, the device can then obtain the channel carrying data information and subsequently retrieve the data information from that channel. Alternatively, the second device can read the puncturing field in the U-SIG of the first PPDU to obtain the puncturing status of the 100MHz channel actually occupied by the first PPDU, thereby retrieving data information from the unpunctured channel.

In one transmission implementation, the 100MHz used to transmit the first PPDU falls within the unlicensed frequency band of 5735MHz to 5835MHz. In this method, the first device can fully utilize the 100MHz corresponding to the unlicensed frequency band of 5735MHz to 5835MHz to transmit data, thereby maximizing the 5.8GHz spectrum utilization, improving spectrum utilization and system throughput, and reducing latency.

Furthermore, the spectrum in the unlicensed band UNII-2A requires dynamic frequency selection (DFS) and transmit power control (TPC) to detect signals such as weather radar, which is complex and prone to false alarms. Therefore, it is difficult to use spectrum greater than 80MHz in the 5.1GHz band. When the 100MHz for transmitting the first PPDU falls within the unlicensed band of 5735MHz to 5835MHz, it is equivalent to adding a 100MHz channel in the UNII-3 section, which makes it easier to use spectrum greater than 80MHz.

One possible implementation is to use a licensed frequency band of 100MHz to transmit the first PPDU. This approach allows the first device to fully utilize this 100MHz bandwidth for data transmission in environments where such bandwidth is relatively available, thereby improving spectrum utilization.

One possible implementation is that, while the first device sends a first PPDU with an actual bandwidth of 100MHz to the second device, it can also send a PPDU with an actual bandwidth of 160MHz to the second device, thereby combining multi-link operation (MLO) to maximize the spectrum utilization of 5GHz.

As can be seen, in this embodiment, the bandwidth field in the first PPDU generated by the first device indicates that the bandwidth of the first PPDU is 160MHz, and the puncturing field indicates that the highest 60MHz of the 160MHz is punctured. Therefore, the actual bandwidth occupied by the first PPDU is 100MHz. Thus, the first device uses the remaining 100MHz channel after puncturing the highest 60MHz of the 160MHz to transmit the first PPDU, achieving 100MHz data transmission. Compared with the first device using PPDUs with predefined protocols to transmit information, this method can improve spectrum utilization.

This application provides a communication method 300, and Figure 55 is an interactive schematic diagram of the communication method 300. The communication method 300 is also described from the perspective of the interaction between a first device and a second device. The communication method 300 includes, but is not limited to, the following steps:

S301. The first device generates an aggregated PPDU with a bandwidth of 100MHz. The aggregated PPDU is obtained by aggregating a second PPDU and a third PPDU, with the second PPDU having a bandwidth of 20MHz and the third PPDU having a bandwidth of 80MHz.

The first device generates a polymerized PPDU, including: generating a second PPDU and a third PPDU; and generating a polymerized PPDU from the second PPDU and the third PPDU.

Alternatively, the aggregated PPDU can be a single PPDU, meaning the first device aggregates the second and third PPDUs to obtain a single PPDU, which is called the aggregated PPDU. Another possible implementation is that the aggregated PPDU consists of two separate PPDUs; for example, the aggregated PPDU includes both the second and third PPDUs.

The second PPDU has a bandwidth of 20MHz, and the third PPDU has a bandwidth of 80MHz. By aggregating the second and third PPDUs, the resulting aggregated PPDU occupies 100MHz of bandwidth. This allows the first device to use 100MHz to transmit the aggregated PPDU, thereby achieving 100MHz data transmission and improving spectrum utilization.

One possible implementation is that the 100MHz of transmission for the aggregated PPDU falls within the unlicensed frequency band of 5735MHz to 5835MHz. In this approach, the first device can fully utilize the 100MHz corresponding to the unlicensed frequency band of 5735MHz to 5835MHz to transmit data, thereby maximizing the spectrum utilization of 5.8GHz, improving spectrum utilization and system throughput, and reducing latency.

One possible implementation is that the 100MHz frequency band for transmitting aggregated PPDUs is within a licensed band. This approach allows the first device to fully utilize this 100MHz bandwidth for data transmission in environments where a relatively available bandwidth exists, thus improving spectrum utilization.

One possible implementation is that the second and third PPDUs are two PPDUs with the same protocol version. For example, both the second and third PPDUs are UHR PPDUs, meaning the aggregated PPDU can be obtained by aggregating two UHR PPDUs with bandwidths of 20MHz and 80MHz respectively, thus the aggregated PPDU can also be considered a UHR PPDU. The UHR PPDU is described in S101 above and will not be repeated here. For example, Figure 56 is a schematic diagram of an aggregated PPDU. As shown in Figure 56, the aggregated PPDU is formed by aggregating two UHR PPDUs with bandwidths of 20MHz and 80MHz respectively.

One possible implementation is that the second and third PPDUs are two PPDUs with different protocol versions. For example, the second PPDU is a UHR PPDU and the third PPDU is an HE PPDU; that is, the aggregated PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 20MHz and an HE PPDU with a bandwidth of 80MHz. For example, Figure 57 is a schematic diagram of another type of aggregated PPDU. As shown in Figure 57, the aggregated PPDU is formed by aggregating a UHR PPDU with a bandwidth of 20MHz and an HE PPDU with an aggregating bandwidth of 80MHz.

For example, the second PPDU is an HE PPDU and the third PPDU is a UHR PPDU. That is, a PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 80MHz and an HE PPDU with a bandwidth of 20MHz.

For example, the second PPDU is a UHR PPDU, and the third PPDU is an EHT PPDU. That is, the aggregated PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 20MHz and an EHT PPDU with a bandwidth of 80MHz. For example, Figure 58 is a schematic diagram of another type of aggregated PPDU. As shown in Figure 58, the aggregated PPDU is formed by aggregating a UHR PPDU with a bandwidth of 20MHz and an EHT PPDU with an aggregating bandwidth of 80MHz.

For example, the second PPDU is an EHT PPDU and the third PPDU is a UHR PPDU. That is, a PPDU can be obtained by aggregating a UHR PPDU with a bandwidth of 80MHz and an EHT PPDU with a bandwidth of 20MHz.

As can be seen, the aggregated PPDU can be obtained by aggregating HE PPDU and UHR PPDU, or by aggregating EHT PPDU and UHR PPDU. In this case, parallel transmission can be supported for traditional users (i.e., users before the UHR standard) and UHR users, maximizing the throughput of traditional users.

In one possible implementation, the aforementioned UHR PPDU can also be replaced with UHR+PPDU, where UHR+PPDU represents PPDUs from 802.11bn onwards. Furthermore, this application does not limit the naming of UHR+PPDU.

S302. The first device uses 100MHz to transmit aggregated PPDU.

Understandably, when the aggregated PPDU consists of two separate PPDUs, the first device sending the aggregated PPDU at 100MHz can mean that the first device uses 100MHz to send the two separate PPDUs in the aggregated PPDU in time alignment.

S303. The second device receives the aggregated PPDU.

S304. Second device analyzes and aggregates PPDU.

The second device parses the aggregated PPDU, including: the second device reads the aggregated PPDU and obtains data information.

As can be seen, in this embodiment of the application, the first device can generate an aggregated PPDU by aggregating the second PPDU and the third PPDU. The aggregated PPDU occupies a bandwidth of 100MHz, so the first device can send the aggregated PPDU to the second device using a 100MHz channel, thereby realizing 100MHz data transmission and improving spectrum utilization.

In addition to the standard definition, the solutions in this application can also be implemented using proprietary solutions or manufacturer-specific features. They are used for communication between devices within the same company or alliance. Before transmitting 100MHz PPDUs between devices, the devices negotiate to adopt the solution described in this application.

Based on the solution of the embodiments of this application, the first PPDU can also carry manufacturer identification information to indicate which manufacturer the PPDU comes from, and can further indicate through the indication of the embodiments of this application that the PPDU adopts the proprietary solution technology of the embodiments of this application.
