In order to facilitate a better understanding of the embodiments of the present application, the related technologies of the present application are first described.

The NR system currently mainly considers two frequency bands, FR1 (Frequency range 1) and FR2 (Frequency range 2). As an example, the frequency domain ranges included in FR1 and FR2 are shown in Table 1.

Table 1

Band Definition Corresponding frequency range FR1 410MHz–7.125GHz FR2 24.25GHz–52.6GHz

With the evolution of the NR system, new frequency bands such as high frequency technologies are also being studied. The frequency domain range included in the new frequency band is shown in Table 2. For convenience of description, it is represented by FRX in this application. It should be understood that the name of this frequency band should not constitute any limitation. For example, FRX can be FR3.

Table 2: New frequency band ranges

Band Definition Corresponding frequency range FRX 52.6GHz–71GHz

The FRX frequency band includes licensed spectrum as well as unlicensed spectrum. In other words, the FRX frequency band includes non-shared spectrum or dedicated spectrum, as well as shared spectrum.

Unlicensed spectrum is the spectrum allocated by countries and regions that can be used for radio equipment communication. This spectrum is generally considered to be shared spectrum, that is, communication equipment in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply for an exclusive spectrum license from the government.

In order to enable various communication systems that use unlicensed spectrum for wireless communication to coexist amicably on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, the communication device follows the principle of "listen before talk (LBT)", that is, before the communication device transmits signals on the unlicensed spectrum channel, it needs to perform channel listening first, and only when the channel listening result is that the channel is idle, the Only the communication device can send the signal; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send the signal. For another example, in order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the channel of the unlicensed spectrum cannot exceed a certain duration. For another example, in order to prevent the power of the signal transmitted on the channel of the unlicensed spectrum from being too large and affecting the transmission of other important signals on the channel, the communication device needs to follow the maximum power spectrum when using the channel of the unlicensed spectrum for signal transmission. Density limit. It should be noted that in some countries or regions, there is no LBT requirement for the unlicensed spectrum included in the FRX frequency band.

Basic concepts of transmission on unlicensed spectrum:

Maximum Channel Occupancy Time (MCOT): Refers to the maximum length of time allowed to use the channel for signal transmission after successful channel sensing on a channel sharing the spectrum.

Channel Occupancy Time (COT): Refers to the length of time that the channel is used for signal transmission after successful channel detection on the shared spectrum channel. It can also be considered as the channel occupied after the successful channel detection on the shared spectrum channel. length of time. Wherein, the signal occupying the channel may be continuous or discontinuous within the time length, and the time length includes the total time for signal transmission by the device initiating the channel occupation and the device sharing the channel occupation.

Channel occupation time of network equipment (gNB/eNB-initiated COT): also known as COT initiated by network equipment, it refers to a channel occupation time obtained by network equipment after successful channel detection on the channel of the shared spectrum. The COT initiated by the network device can not only be used for transmission by the network device, but also can be used for transmission by the terminal device under certain conditions.

UE-initiated COT (UE-initiated COT): Also known as COT initiated by the terminal device, it refers to the channel occupancy time obtained by the terminal device after successful channel detection on the channel of the shared spectrum. The COT initiated by the terminal device can not only be used for transmission by the terminal device, but also can be used for transmission by the network device under certain conditions.

Downlink transmission opportunity (DL transmission burst): A group of downlink transmissions (that is, including one or more downlink transmissions) performed by a network device, the group of downlink transmissions are continuous transmissions (that is, there is no gap between multiple downlink transmissions), or the group of downlink transmissions There is a gap in the downlink transmission but the gap is less than or equal to a preset value, for example, in the FR1 frequency band, the preset value is 16 μs. If the gap between two downlink transmissions performed by the network device is greater than the preset value of 16 μs, it is considered that the two downlink transmissions belong to two downlink transmission opportunities.

Uplink transmission opportunity (UL transmission burst): A group of uplink transmissions (that is, including one or more uplink transmissions) performed by a terminal device, the group of uplink transmissions are continuous transmissions (that is, there is no gap between multiple uplink transmissions), or the There is a gap in the group uplink transmission but the gap is less than or equal to a preset value, for example, in the FR1 frequency band, the preset value is 16 μs. If the gap between two uplink transmissions performed by the terminal device is greater than the preset value of 16 μs, the two uplink transmissions are considered to belong to two uplink transmission opportunities.

It should be understood that in the FRX frequency band, the above-mentioned preset value may be other values, for example, 8 μs. This application is not limited to this.

Channel Detection Success: Also known as LBT Success or Channel Detection Idle. For example, the energy detection in the listening time slot performed on the channel is below the energy detection threshold.

Channel Detection Failed: Also known as LBT Failure or Channel Detection Busy. For example, the energy detection in the listening time slot of the channel is higher than or equal to the energy detection threshold.

Receive-side assisted channel access

Auxiliary channel monitoring on the receiving side is an LBT method based on the Request To Send/Clear To Send (RTS/CTS) mechanism. as shown in picture 2. Before the network device transmits, it first sends a signal similar to RTS to inquire whether the terminal device is ready to receive data. After the terminal device receives the RTS signal, if the LBT process is successful, it can send a signal similar to CTS to the network device, such as reporting its own interference measurement result, informing the network device that it is ready to receive data. After the CTS, downlink transmission can be performed to the terminal equipment. Or, if the terminal receives the RTS and the device does not receive the RTS, or the terminal receives the RTS but cannot send the CTS due to the failure of the LBT process, the terminal will not send the CTS signal to the network device, and the network device will not receive the CTS signal from the terminal In this case, the downlink transmission to the terminal equipment can be abandoned.

Channel access corresponding to unlicensed spectrum on the FRX band

On the FRX frequency band, for countries and regions that have LBT requirements, the LBT mode (ie, channel access mode) can include omnidirectional LBT, directional LBT, receiving-side auxiliary LBT, and no LBT. Among them, the channel access mode without LBT may also need to be limited by certain conditions, such as automatic transmit power control ATPC, DFS, long-term interference detection or other interference elimination mechanisms. In addition, it is possible to switch between channel access with LBT and channel access without LBT.

For countries and regions without LBT requirements, it is also necessary to consider whether to introduce certain conditions, such as whether to apply DFS, apply ATPC, apply long-term interference detection, limit a certain duty cycle (duty cycle), limit a certain transmit power, limit MCOT and many more.

After the introduction of the FRX frequency band, due to the relatively high frequency band, the LBT method on the unlicensed spectrum on the FRX frequency band is different from the LBT method on the unlicensed spectrum on the FR1 frequency band. For example, in the FRX frequency band, a channel access method based on transceiver interaction, which is also called a receiving-side auxiliary channel access method, may be introduced. Therefore, how to support the receiving side auxiliary channel access (or called receiving side auxiliary channel detection, receiving side auxiliary LBT) method in the NR-U system on the FRX frequency band is an urgent problem to be solved.

As another implementation manner, the transmission request information multiplexes an existing information field in the first control information format. With this implementation, control information overhead can be reduced.

As an example, the first control information format is a DCI format for scheduling PDSCH or activating SPS PDSCH transmission. The first device is a terminal device, and the second device is a network device. If the terminal device receives the first control information including the transmission request information, the terminal device determines to send response information to the network device.

If the terminal device receives the first control information including the transmission request information, the terminal device determines to send response information to the network device. Further, when the terminal device sends the response information to the network device, the terminal device sends the PUSCH scheduled by the first control information or sends the CG PUSCH activated by the first control information.

As yet another example, the first control information format is a DCI format for releasing SPS PDSCH or releasing CG PUSCH.

As an example, it is assumed that the transmission request information may be included in the DCI format 1_1 in which the network device schedules the PDSCH through high-layer parameter configuration, and the format indication information is included in the DCI format 1_1. When the terminal device receives the DCI corresponding to DCI format 1_1, if the format indication information in the DCI indicates that the DCI includes transmission request information, the terminal device interprets the DCI according to the information field corresponding to the transmission request information; The format indication information indicates that the DCI does not include transmission request information, and the terminal device interprets the DCI according to the information field corresponding to the scheduling PDSCH.

In other embodiments, whether the second device initiates the request-response process to the first device may be determined according to the content of the transmission request information. For example, the transmission request information includes a resource for transmitting the response information, and the second device may be considered to initiate the request-response process to the first device when transmitting relevant information such as a beam of the response information.

That is, the transmission request information can be used to determine whether the second device initiates a request-response process to the first device, and/or the resource, beam, channel access mode and other related information of the first device to send the response information.

The specific implementation of the transmission request information will be described below with reference to specific embodiments. It should be understood that the following information content is only an example, but the present application is not limited thereto.

In some embodiments of the present application, the transmission request information includes at least one of the following information:

First indication information, at least one frequency domain resource indication information, beam indication information, response resource indication information and channel access indication information, wherein the first indication information is used to indicate whether to initiate the request-response process.

In some embodiments, the number of bits occupied by the first indication information in the first control information is configured by a network device, for example, configured by a high layer parameter.

In some other embodiments, the number of bits occupied by the first indication information in the first control information is configured by a third device having a management control function, such as a third terminal device, for example, configured through high-level parameters.

The control node of the second terminal device is, for example, a group head terminal of a terminal group to which the second terminal device belongs.

In some cases, the third terminal device and the second terminal device may be the same terminal device. In other cases, the third terminal device and the first terminal device may be the same terminal device, and the group head terminals corresponding to the first terminal device and the second terminal device are the same terminal device.

In still other embodiments, the number of bits occupied by the first indication information in the first control information may also be predefined.

That is, the number of bits occupied by at least one type of information included in the transmission request information in the first control information is determined according to a high-level parameter configured by the network device or the third device; or, the transmission request The number of bits occupied by at least one type of information included in the information in the first control information is predefined.

Taking the response resource indication information as an example, for example, assuming that the network device configures the response resource indication information to correspond to M states through high-level parameters, or the response resource indication information is predefined to correspond to M states, then the response resource indication information is in the first state. The corresponding number of bits in the control information format is ceil(log2(M)) bits, where log2 represents the logarithm with the base 2, and ceil represents the rounding up. For example, M=8, and the corresponding number of bits is 3 bits.

In some embodiments, the first indication information is used to indicate whether the second device initiates the request-response process to the first device.

As an example, the first indication information is 1 bit, and the value of the 1 bit is used to indicate whether the second device initiates the request-response process to the first device.

For example, when the 1-bit value is a first preset value, such as 1, it is used to instruct the second device to initiate the request-response process to the first device, and the 1-bit value is the second preset value. When the value is set to 0, for example, it is used to indicate that the second device does not initiate the request-response process to the first device.

In this case, it may be considered that the first indication information is related to the frequency domain resource associated with the first control information. For example, if the first control information is used to schedule or activate physical channel or physical signal transmission on a first bandwidth part (Bandwidth Part, BWP), the first indication information is associated with the first BWP.

In some embodiments, the first indication information is carried in a dedicated information field in the first control information. For example, an information field may be added to the first control information for carrying the first indication information.

In other embodiments, the first indication information may multiplex an existing information field in the first control information.

As an example, the first control information includes a first information field, and the first indication information is represented by a first state of the first information field in the first control information. For example, when the value of the first information field is the first state, the first information field is used to indicate that a request-response process is not initiated to the first device. For another example, when the value of the first information field is not the first state, the first information field is used to determine whether to initiate the request-response process, or the first information field is not used to determine whether to initiate the request-response process. That is, when the value of the first information field is the first state, the first information field is interpreted according to the first indication information, and when the first information field is not in the first state, it is interpreted according to the original meaning of the first information field.

In some embodiments of the present application, the first state may be an invalid state or a reserved state.

In some embodiments of the present application, the first information field includes at least one information field.

For example, the first information field is the information field corresponding to the response resource indication information. If the response resource indication information indicates an invalid response resource, for example, the time domain location of the response resource is not indicated, it means that the second device does not send the first device to the Initiate the request-response process; or, if the response resource indication information indicates a valid response resource, it means that the information field is interpreted according to the response resource indication information, and the second device initiates the request-response to the first device. The response process, wherein the response resource used in the request-response process is determined according to the valid response resource indicated by the response resource indication information.

As another example, the first indication information is represented by the value of some or all bits of the first control information being the second state. For example, when the value of part or all of the bits in the first control information is the second state, the first indication information indicates that the request-response process is not to be initiated, or in other words, the first A control message indicates that the request-response procedure is not initiated.

For example, the value of the M bits in the first control information can be used to indicate the first state. If the M bits are all "1" or all "0", it indicates that the first device has not been initiated the request-response process; otherwise, the M bits are interpreted normally.

In some embodiments of the present application, the at least one frequency domain resource indication information is associated with at least one cell or at least one BWP or at least one frequency domain resource set, or in other words, each frequency domain in the at least one frequency domain resource indication information The domain resource indication information is associated with a cell or a BWP or a frequency domain resource set. Wherein, the first frequency domain resource indication information in the at least one frequency domain resource indication information is associated with the first cell or the first BWP or the first frequency domain resource set. The first frequency domain resource indication information is used to indicate whether the second device initiates the request to the first device on the first cell or the first BWP or the first frequency domain resource set - a response process, or the first frequency domain resource indication information is used to indicate whether to initiate a request-response process corresponding to the first cell or the first BWP or the first frequency domain resource set, or, The first frequency domain resource indication information is used to indicate that the acknowledgement information is associated with the first cell or the first BWP or the first frequency domain resource set.

The request-response process, wherein the second cell and the first cell have a corresponding relationship.

As an example, the first frequency domain resource indication information is 1 bit, and the value of the 1 bit is used to indicate whether the second device initiates the first device corresponding to the first cell request-response process. For example, when the value of the 1 bit is a first preset value such as 1, it is used to instruct the second device to initiate the request-response process corresponding to the first cell to the first device, and the When the value of 1 bit is a second preset value such as 0, it is used to instruct the second device to initiate the request-response process corresponding to the first cell to the first device.

It should be understood that, in the above example, the first cell can also be replaced with other frequency domain concepts, such as BWP, or a frequency domain resource set, etc., which is not limited in this embodiment of the present application, that is, the frequency domain resource indication information can be related to the cell Associated, or associated with the BWP, or associated with the frequency domain resource set, etc.

In some embodiments, the frequency domain resource indication information is carried in a dedicated information field in the first control information. For example, an information field may be added to the first control information for carrying the frequency domain resource indication information.

In other embodiments, the frequency domain resource indication information may multiplex an existing information domain in the first control information.

As an example, the first control information includes a second information field, and the frequency domain resource indication information is indicated by a first state of the second information field in the first control information.

For example, when the value of the second information field is the first state, the second information field is used to indicate that the second device does not initiate the associated cell or BWP or frequency domain resources to the first device Set the corresponding request-response process. For another example, when the value of the second information field is not the first state, the second information field is not used to determine whether to initiate the request-response process. For another example, when the value of the second information field is not the first state, the second information field is used to determine that the second device initiates an associated cell or BWP or frequency domain resource to the first device Set the corresponding request-response process.

That is, when the value of the second information field is the first state, the first information field is interpreted according to the frequency domain resource indication information, and when the second information field is not in the first state, it is interpreted according to the original definition of the second information field.

For example, the second information field is the information field corresponding to the response resource indication information, and includes N bits. If the N bits are all "1" or all "0", it means that the second device does not report to the first A device initiates the request-response process corresponding to the associated cell or BWP or frequency domain resource set; otherwise, it means that the information domain is interpreted according to the response resource indication information.

In some embodiments of the present application, the first state may be an invalid state or a reserved state.

For example, when the value of some or all of the bits in the first control information is the second state, it indicates that the second device does not send the first information to the first control corresponding to the associated cell or BWP or frequency domain resource set. A device initiates the request-response procedure.

Take the BWP associated with the frequency domain resource indication information as an example. As an example, if the terminal device is configured with N BWPs, the frequency domain resource indication information includes N bits, where each bit corresponds to one BWP. When a certain bit indicates a preset value such as "1", it is used to indicate that a request-response process corresponding to the BWP is initiated; when a certain bit indicates another preset value such as "0", it is used to indicate that no pairing has been initiated. The request-response process of the BWP, where N is a positive integer.

When a certain bit indicates a preset value such as "1", it is used to indicate that a request-response process corresponding to the BWP is initiated; when a certain bit indicates another preset value such as "0", it is used to indicate that no pairing has been initiated. Should BWP's request-response process.
