This UCI is transmitted. The transmission method is also called UCI piggyback on PUSCH (UCI piggyback on PUSCH). Moreover, it is considered that the importance of the UCI is greater than the uplink data itself carried by the PUSCH, and thus the modulation and coding scheme (MCS) offset value of the UCI is set to be greater than or equal to 1.

However, when the UCI is carried on the PUSCH, the UCI occupies a part of the resources originally used to carry the uplink data, so that the available resources of the uplink data itself are reduced, the coding rate of the uplink data is improved, and the reliability of the uplink data transmission is reduced. .

Step 11: The network device sends downlink control information (DCI), where the DCI is used to schedule an uplink data channel, such as a physical uplink shared channel (PUSCH), which may be referred to as an uplink grant (UL grant). The transmission resource of the PUSCH scheduled by the DCI overlaps with the transmission resource time domain of the physical uplink control channel PUCCH, and the PUCCH is used to carry the uplink control information UCI to be transmitted. FIG. 3 illustrates various possible scenarios in which a PUSCH and a PUCCH overlap with a time domain resource, for example, a time domain resource of a PUSCH completely coincides with a time domain resource of a PUCCH, or a time domain resource of a PUSCH partially overlaps with a time domain resource of a PUCCH, Or the time domain resource of the PUSCH includes the time domain resource of the PUCCH and occupies more time domain resources, or the time domain resource of the PUCCH includes the time domain resource of the PUSCH and occupies more time domain resources. The time domain resource of the PUCCH may be determined according to the indication information sent by the network device, and the indication information may be carried in the signaling sent by the network device to the terminal device. The signaling in the embodiment of the present application may be radio resource control (RRC) signaling, medium access control (MAC) control element (CE) or physical layer signaling, where Physical layer signaling can be DCI. The PUCCH is used to carry the UCI, wherein the UCI may be a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK), and periodic channel state information. , P-CSI), one or more of semi-persistent channel state information (SP-CSI) and aperiodic channel state information (A-CSI), wherein In the following content, HARQ-ACK/NACK is abbreviated as HARQ, and P-CSI, SP-CSI, and A-CSI include part1 and part2, and P-CSI, SP-CSI, and A-CSI are also available. Collectively referred to as channel state information (CSI).

Step 12: The terminal device receives the DCI of the scheduled PUSCH, and determines, according to the DCI, a transmission resource of the physical uplink shared channel PUSCH scheduled by the DCI.

Step 13. When the first condition is met, the terminal device sends uplink data on the PUSCH, and does not send the UCI on the PUSCH. The first condition may be implemented in multiple manners, for example, the format of the DCI for scheduling the PUSCH is a format agreed by the protocol, or the DCI includes specific information, or the TBS of the uplink data carried by the PUSCH and/or the UCI. The load size is in accordance with the convention, or the terminal device receives the indication information indicating that it does not carry the UCI on the PUSCH.

Step 14: The network device receives the PUSCH, where the PUSCH does not carry the UCI when the first condition is met.

In the foregoing technical solution, the network device sends the DCI for scheduling the PUSCH to the terminal device, and the terminal device may determine, according to the DCI or other indication information, that the UCI is not sent on the PUSCH, that is, the UCI piggyback on PUSCH is prohibited, thereby ensuring the uplink data transmitted on the PUSCH. reliability.

It should be understood that, in step 14, the network device may determine that the first condition in step 13 is established before receiving the PUSCH, so as to determine that the UCI is not carried on the PUSCH, and the network device may receive the uplink data on the PUSCH without receiving the UCI. .

It should be understood that the time domain resource of the PUSCH may overlap with the time domain resources of multiple PUCCHs. Each PUCCH of the multiple PUCCHs is used to carry the UCI to be transmitted. When the first condition is established, the terminal device may not send the UCI on the PUSCH. .

As an optional design, the first condition in step 13 may be: scheduling the DCI of the PUSCH to satisfy any of the following:

A1. The payload size of the DCI is equal to a first value, where the first value is a minimum value of the DCI of the scheduling PUSCH, and the DCI load size of the scheduling PUSCH or its minimum value may be predefined or configured by higher layer signaling. Configuration.

The load size of the DCI is smaller than the first threshold, and the first threshold is less than or equal to the load size of the fallback DCI, where the back-off DCI is used to schedule the PUSCH or the physical downlink shared channel (physical downlink shared) Channel, PDSCH), and the inclusion field of the fallback DCI and the meaning of each field are predefined, regardless of the high layer configuration. Please refer to various prior art for the specific implementation of the fallback DCI. For example, the fallback DCI is Format 0_0 and 1_0 in the NR Release 15 (NR Rel-15).

A3. The load size of the DCI is equal to the second value, and the value of the DCI format identifier field in the DCI is equal to the third value, and the second value may be the load size of the DCI to be rolled back, and the value of the DCI format identifier field is equal to The third value is used to indicate that the DCI is not a fallback DCI.

A4. The load size of the DCI is equal to the second value, and the search space of the DCI is a user equipment UE specific search space, and the UE specific search space may be predefined or configured by high layer signaling.

A6. The load size of the DCI is equal to the second value. The value of the DCI format identifier field in the DCI is equal to the third value, and the search space of the DCI is the UE-specific search space.

A7. The beta offset in the DCI indicates that the beta offset beta-offset indicated by the beta-offset indicator field has a value of zero. The beta-offset indicator field is used to indicate the value of the beta-offset. For example, the beta-offset indicator field itself may be represented by multiple values. For example, when the beta-offset indicator field has a width of 2 bits, the field may have 4 The values are '00', '01', '10', '11'. A value of a beta-offset indicator field may correspond to a beta-offset value, such as a beta-offset value of 0 when the beta-offset indicator field is 00, and a beta-offset when the beta-offset indicator field is 01. The value is 1. A value of a beta-offset indicator field can also correspond to a set of beta-offset values. For example, if the beta-offset indicator field is 00, it corresponds to three values of beta-offset1, beta-offet2, and beta-oset3, respectively. The values of the beta-offset corresponding to the HARQ-ACK, the CSI part 1, and the CSI part 2 are indicated. In the embodiment of the present application, when the value of one beta-offset indicator field corresponds to multiple beta-offset values, the value of the beta-offset indicated by the beta-offset indicator field in the DCI refers to The maximum of the values of the plurality of beta-offsets indicated by the beta-offset indicator field. The beta-offset is used to characterize the MCS offset value, and can be used to determine the amount of resources (such as the number of resource elements (RE)) occupied by the UCI carried on the PUSCH. When the value of the beta-offset is 0, it indicates that the number of REs occupied by the UCI when transmitting on the PUSCH is 0, which indirectly indicates that the UCI does not need to be carried on the PUSCH for transmission.

The value of the beta-offset indicator in the DCI is a fourth value, and the fourth value is used to indicate that the terminal device does not send the UCI on the PUSCH.

A9: The value of the beta-offset indicated by the beta-offset indicator field in the DCI is less than or equal to a fifth threshold, and the fifth threshold may be configured by the network device to the terminal device by using signaling.

It should be understood that the foregoing second value, the third value, the fourth value, the first threshold, and the fifth threshold may be predefined, or may be configured by the network device to the terminal device by using signaling. When any of the above conditions a1 to a9 is established, it may indicate that the uplink data carried by the PUSCH may be the data of the URLLC service, or the transmission reliability of the uplink data carried by the PUSCH is high.

The load size of the UCI may be the number of original information bits of the UCI, or may be the UCI added check information (such as a cyclic redundancy check). The number of information bits after CRC)) may also be UCI added check information and the number of equivalent information bits after considering beta-offset. In addition, when one PUCCH carries multiple types of UCI information (such as HARQ and A-CSI), the payload size of the UCI is the sum of the payload sizes of all types of UCI information carried by the PUCCH. The specific determination method of the load size of the UCI can refer to various technical means in the prior art.

B2. The TBS of the uplink data carried by the PUSCH is less than or equal to a third threshold. The determining manner of the TBS of the uplink data may refer to various technical means in the prior art. The TBS of the uplink data may be determined according to information such as resource allocation in the DCI, and may refer to various prior art means.

B3. The ratio of the load size of the UCI to the TBS of the uplink data is greater than or equal to a fourth threshold.

It should be understood that the foregoing second threshold value, the third threshold value, and the fourth threshold value may be predefined, may also be configured by RRC signaling, and may also be indicated by a DCI sent by a MAC CE or a network device. When any of the above conditions b1 to b3 is established, it may indicate that the uplink data carried by the PUSCH may be the data of the URLLC service, or the transmission reliability of the uplink data carried by the PUSCH is high.

In the foregoing technical solution, the terminal device may determine that the UCI is not sent on the PUSCH according to the payload size of the TBS and/or UCI of the uplink data carried by the PUSCH scheduled by the network device, and the reliability of the uplink data is ensured.

It should be understood that when the time domain resource of the PUSCH overlaps with the time domain resources of multiple PUCCHs, the payload size of the UCI in the conditions b1 and b3 may refer to the sum of UCIs of all PUCCHs overlapping with the PUSCH time domain, and is established in the condition b1 or b3.

It can be understood that, in the embodiment of the present application, the PDSCH, the PDCCH, the PUSCH, and the PUCCH are only examples of the downlink data channel, the downlink control channel, the uplink data channel, and the uplink control channel, in different systems and different scenarios. The data channel and the control channel may have different names, which is not limited by the embodiment of the present application.

In the embodiment of the present application, the high layer signaling may be RRC signaling, or may be a medium access control (MAC) control element (CE).

In the foregoing technical solution, the network device sends the DCI for scheduling the PUSCH to the terminal device, and the terminal device may determine, according to the DCI or other indication information, that not all the content of the UCI is sent on the PUSCH, but only part of the UCI is sent on the PUSCH, thereby ensuring The reliability of the uplink data transmitted on the PUSCH.

It should be understood that, in step 24, before receiving the PUSCH, the network device may determine that the first condition in step 23 is established, thereby determining to carry a part of the UCI on the PUSCH, and the network device may receive a part of the UCI on the PUSCH.

It should be understood that the time domain resource of the PUSCH may overlap with the time domain resources of multiple PUCCHs, and each PUCCH of the multiple PUCCHs is used to carry the UCI to be transmitted. When the first condition is established, the terminal device may carry a part of the UCI corresponding to each PUCCH in all the PUCCHs that overlap with the PUSCH time domain, and transmit all or part of the partial PUCCH corresponding to the PUSCH time domain. The UCI is carried on the PUSCH.

As an optional design, the first condition in step 23 may be any one of the foregoing conditions a1 to a7, a9, b1 to b3, c1 to c3; or the first condition is: beta-offset in the DCI The value of the indicator is a fifth value, the fifth value is used to indicate that the terminal device carries a part of the UCI on the PUSCH, and the fifth value can be configured by the network device to the terminal device by using signaling, and the fifth value can be The same as the aforementioned fourth numerical value, it may be different.

A possible implementation manner in which all the UCIs carried by a part of the PUCCHs that the terminal equipment overlaps with the PUSCH time domain are carried on the PUSCH are listed. If the UCI on the partial PUCCH does not satisfy the above b1 or b3, the terminal device may transmit the UCI of the PUCCH that does not satisfy the condition b1 or b3 on the PUSCH. For example, the terminal device may determine the UCI with the smallest payload size among the plurality of UCIs, determine whether the UCI satisfies the condition b1 or b3, and if not, determine that the UCI with the smallest load may be transmitted on the PUSCH. Optionally, the terminal device may further determine whether the sum of the second smallest UCI of the load size and the UCI load size of the smallest load size satisfies the condition b1 or b3, and if not, determine that the load can be sent on the PUSCH. The smallest UCI and the second smallest UCI load, and so on, until the plurality of UCIs with the smallest load do not satisfy the above condition b1 or b3. The above technical solution can transmit as much UCI as possible on the PUSCH on the basis of ensuring the reliability of the uplink data, and not only can fully utilize the transmission resources, but also can transmit the UCI in time to improve the communication efficiency with the network device.

As an optional design, before step 23, the following steps are also included:

The network device sends indication information indicating that a portion of the UCI is carried on the PUSCH. The network device may send the indication information to the terminal device when determining that the transmission reliability requirement of the uplink data carried by the PUSCH is high.

And, the terminal device receives the indication information.

Then, the first condition in step 23 is that the indication information received by the terminal device indicates that a part of the UCI is carried on the PUSCH. The specific form of a part of the UCI may be predefined, may also be configured by RRC signaling, and may also be indicated by the MAC CE, the DCI sent by the network device, or the indication information itself.

In the above technical solution, the network device may send, to the terminal device, indication information indicating that only a part of the UCI is carried on the PUSCH, and the terminal device transmits only a part of the UCI on the PUSCH according to the indication information, thereby ensuring the reliability of the uplink data.

As an optional design, a part of the UCI in step 23 may be determined according to the first information bit number and the priority of various types of information included in the UCI, and may include the following processes:

First, the terminal device determines the transmission priority of the UCI, and may set HARQ>CSI part 1>CSI part 2. When the information bit of the HARQ is larger than the first information bit number, all the information bits of the HARQ may be selected not to be transmitted, or the HARQ may be transmitted on the PUCCH truncated resource. When the information bit of the HARQ is less than or equal to the first information bit number, but the information bit of the CSI part 1+HARQ is greater than the first information bit number, the HARQ is carried on the PUSCH, and the CSI part 1 is not carried, and the CSI part 1 may not be sent. Or send CSI part 1 on the PUCCH truncated resource. When the information bit of the HARQ+CSI part 1 is less than or equal to the first number of information bits, but the information bits of the CSI part 2+CSI part 1+HARQ are greater than the first number, the HARQ and the CSI part 1 are carried on the PUSCH, and the CSI part 2 is not carried. You can send CSI part 2 without sending CSI part 2 or on the PUCCH truncated resource. The number of the first information bits may be predefined, may also be configured by RRC signaling, and may also be indicated by a DCI sent by the MAC CE or the network device.

The foregoing technical solution can effectively determine UCI information that has less impact on uplink data reliability and higher priority, and carries it on the PUSCH for transmission, taking into consideration the efficiency and reliability of communication between the network device and the terminal device.

As an optional design, if the first condition is met, the terminal device discards the portion of the UCI that is not transmitted on the PUSCH. It should be understood that when the time domain resource of the PUSCH overlaps with the time domain resources of multiple PUCCHs, the terminal device may discard the portion of the UCI of all PUCCHs that overlap with the PUSCH time domain resource that is not transmitted on the PUSCH.

As an optional design, after step 22, the following steps are also included:

If the first condition is met, the HARQ or the A-CSI in the UCI is carried on the PUSCH, the terminal device transmits the remaining portion of the UCI on the PUCCH truncated resource, and the remaining portion of the UCI refers to the content of the UCI that is not sent on the PUSCH. .

And, the network device receives the remaining portion of the UCI transmitted on the PUCCH truncated resource. For example, referring to FIG. 8, the terminal device transmits uplink data and HARQ in the UCI on the PUSCH, and transmits A-CSI on the PUCCH truncated resource.

In the foregoing technical solution, the terminal device can transmit the remaining part of the UCI on the PUCCH truncated resource, and can not only fully utilize the transmission resource, but also can ensure that the reliability of the uplink data is required to be transmitted only on the PUSCH. Send all the contents of UCI in time to improve communication efficiency with network devices.

It should be understood that when the time domain resource of the PUSCH overlaps with the time domain resources of multiple PUCCHs, the terminal device may send the PUC of the PUCCH on the PUSCH that is not on the PUSCH on the truncated resource of all or part of the PUCCH overlapping with the PUSCH time domain. The part sent.

FIG. 9 shows another uplink information transmission method provided by an embodiment of the present application, where the method includes the following steps:

Step 31: The network device sends a DCI, where the DCI is used to schedule the PUSCH.

Step 32: The terminal device receives the DCI sent by the network device, and determines, according to the DCI, a transmission resource of the PUSCH scheduled by the DCI.

Step 33: When the UCI is transmitted through the PUSCH, the terminal device determines the first TBS of the uplink data sent on the PUSCH according to the total RE number of the transmission resources of the PUSCH and the payload size of the UCI carried on the PUSCH. The UCI may be a UCI to be transmitted carried by the PUCCH that overlaps with the time domain resource of the PUSCH, or may be a UCI carried by the network device that is scheduled by the network device.

Step 34: The terminal device sends the uplink data and the UCI on the PUSCH according to the first TBS, where the TBS that sends the uplink data on the PUSCH is the first TBS.

Step 35: The network device determines, according to the total RE number of the transmission resources of the PUSCH and the payload size of the UCI carried on the PUSCH, the first TBS of the uplink data sent on the PUSCH. The manner in which the network device determines the first TBS in step 35 may be the same as the manner in which the terminal device determines the first TBS in step 33.

Step 36: The network device receives uplink data and the UCI on the PUSCH according to the first TBS.

It should be understood that step 35 may be performed at a time after step 31. For example, step 35 may be performed earlier than step 34, or may be performed earlier than step 32 or step 33, or may be performed after step 34.

In the prior art, when the UCI is transmitted through the PUSCH, the terminal device increases the coding rate of the uplink data, and if the transmission resource of the PUSCH is occupied by the UCI, continues to transmit all the information determined without considering carrying the UCI. Upstream data. Compared with the foregoing prior art, the technical solution provided by the present application determines the TBS of the uplink data to be sent in combination with the occupation of the PUSCH resources by the UCI, and avoids the excessive number of uplink data to be transmitted, thereby reducing the transmission reliability of the uplink data.

In an optional design, referring to FIG. 10, in step 33, the terminal device determines, according to the total RE number of the transmission resources of the PUSCH and the payload size of the UCI carried on the PUSCH, the uplink sent on the PUSCH. The first TBS of the data may specifically be:

Step 331: The terminal device determines a total number of REs of the transmission resources of the PUSCH, and determines a first intermediate value according to the total number of REs, where the first intermediate value is used to represent a second when the uplink data is sent on the PUSCH and the UCI is not sent. TBS. The manner of determining the total number of REs of the transmission resources of the PUSCH may refer to various prior art means, and the first intermediate value may be an intermediate quantity N _info for determining the second TBS, for example, N _info =N _RE ·R Q·v, where N _RE is the total number of _REs of the transmission resources of the PUSCH, and R, Q, and v are the target coding rate, the modulation order, and the number of transmission layers of the PUSCH transmission, respectively, by performing the first intermediate value The second TBS can be determined by quantization and/or table lookup processing. It should be noted that the first intermediate value may also be the second TBS obtained by the intermediate quantity N _info according to the quantization and/or table lookup process.

The quantization and/or table lookup process in the embodiment of the present application may refer to steps 2), 3) and 4) in the protocol TS 38.214 vf.0.0 Section 5.1.3.2, or may be a simplification or other improvement of the above process.

Step 332: The terminal device determines the first TBS according to the first intermediate value and the load size of the UCI.

Step 332 can have multiple implementations, including but not limited to:

Mode 1, determining, according to the first intermediate value and the payload size of the UCI, the number of REs occupied by the UCI when transmitting on the PUSCH; and subtracting the number of REs occupied by the UCI when transmitting on the PUSCH according to the total number of REs The remaining number of REs determines the first TBS.

Wherein, since the number of coding modulation symbols per layer occupied by the PUSCH transmission of the UCI information is equal to the number of REs occupied by the UCI when transmitting on the PUSCH, the number of coded modulation symbols occupied by the UCI in the PUSCH transmission can be calculated as UCI. The number of REs used when transmitting on the PUSCH.

For example, the number of REs occupied by HARQ can be:

The number of REs occupied by CSI part 1 can be:

The number of REs occupied by CSI part 2 can be:

It should be understood that, in the formula, O _ACK , O _{CSI, 1} , O _{CSI, 2} may be 0, indicating that no corresponding UCI needs to carry transmission on the PUSCH.

根据该剩余的RE数目确定第一TBS的方式可以为：根据第二中间值

进 行量化和/或查表处理，确定该第一TBS。 It should be understood that when the UCI includes multiple types of UCI information, the number of REs occupied by the UCI when transmitting on the PUSCH is the sum of the number of REs occupied by all types of UCI information, labeled Q' _UCI . Then, the total number of REs minus the number of REs remaining after the number of REs occupied by the UCI on the PUSCH is transmitted

The manner of determining the first TBS according to the remaining number of REs may be: according to the second intermediate value

A quantization and/or lookup process is performed to determine the first TBS.

And determining, according to the first intermediate value and the load size of the UCI, the number of REs occupied by the UCI when transmitting on the PUSCH; determining a third intermediate value according to the number of REs occupied by the UCI when transmitting on the PUSCH, The third intermediate value is used to represent the number of information bits that the UCI can occupy on the PUSCH when carrying the transmission, and the number of information bits that can be carried by using the specified coding adjustment scheme and the transmission scheme. A possible calculation manner of the third intermediate value is: Q _UCI = Q' _UCI · R · Q · v, another possible calculation of the third intermediate value is: Q _UCI = Q' _ACK * R * Q * v + Q ' _{CSI, 1} * R * Q * v + Q ' _{CSI, 2} *R*Q*v. Then, the first TBS is determined according to the first intermediate value and the third intermediate value. For example, the first TBS can be determined by performing quantization and/or look-up according to the difference N _info -Q _{UCI of the} first intermediate value and the third intermediate value.

In the foregoing various implementation manners, the terminal device may determine the TBS of the uplink data to be sent according to the UCI occupying the PUSCH resource, and avoid the excessive number of uplink data to be transmitted, thereby reducing the transmission reliability of the uplink data.

In an optional design, in step 33, the terminal device determines, according to the total RE number of the transmission resources of the PUSCH and the payload size of the UCI carried on the PUSCH, the first uplink data sent on the PUSCH. TBS, specifically can be:

Determining the first TBS according to the first intermediate value and the load size of the UCI; wherein the first intermediate value and the total RE number satisfy a first functional relationship. For example, the first functional relationship between the first intermediate value N _info and the total RE number N _RE may be: N _info =f ₁ [g ₁ (N _RE )·R·Q·v]. Where R, Q, and v are the target coding rate, modulation order, and number of transmission layers of the PUSCH transmission, respectively; g ₁ (N _RE ) indicates potential quantization processing on the total number of REs, and one possible implementation manner is not to quantize Processing, ie g ₁ (N _RE )=N _RE ; f ₁ (x) denotes a potential quantization (including table lookup) process on the input variable x, a possible implementation is to not perform quantization processing, ie f ₁ ( x) = x. Optionally, the first intermediate value is used to represent the second TBS when the uplink data is sent on the PUSCH and the UCI is not sent.

Optionally, determining the first TBS according to the first intermediate value and the load size of the UCI may include the following steps:

Determining the first TBS according to the total number of REs minus the number of REs occupied by the UCI when transmitting on the PUSCH; wherein, the number of REs occupied by the UCI when transmitting on the PUSCH and the first intermediate value And the load size of the UCI satisfies the second functional relationship.

The second function relationship between the number of REs occupied by the UCI on the PUSCH and the first intermediate value Q' _UCI and the first intermediate value N _info is: Q' _UCI = Q' _ACK + Q' _{CSI, 1} +Q' _{CSI, 2} . Where Q' _ACK , Q' _{CSI, 1} , Q' _{CSI, 2} are HARQ, CSI part 1 and CSI part 2, respectively, the number of REs occupied in PUSCH transmission, Q' _ACK , Q' _{CSI, 1} , Q' _CSI, The calculation method of ₂ is as above.

Optionally, determining the first TBS according to the first intermediate value and the load size of the UCI may include the following steps:

The fourth function relationship is seen in the second function relationship, and the two are the same. Second intermediate value

The third functional relationship between the number of REs Q' _UCI occupied when the UCI is transmitted on the PUSCH is

g ₂ (N _RE ) denotes a potential quantization process for the total number of REs. One possible implementation is that no quantization process is performed, ie g ₂ (N _RE )=N _RE ; f ₂ (x) represents the input variable x A potential quantification (including lookup table) processing, one possible implementation is to not perform quantization processing, ie f ₂ (x)=x.

In the above multiple optional designs, the TBS of the uplink data to be transmitted is determined by the UCI's occupation of the PUSCH resources, and the excessive transmission of the uplink data is prevented, so that the transmission reliability of the uplink data is reduced.

Although the above method embodiments are described from the perspective of scheduling-based uplink data transmission, the design idea of the present application can also be applied to uplink data transmission based on unauthorized.

The uplink data transmission without grant is an "arrive-and-go" uplink data transmission method, that is, when the data arrives, the terminal device does not need to send a scheduling request to the network device ( Scheduling request (SR), there is no need to wait for the network device to send an authorization, but directly use the pre-allocated resources of the network device and the specified transmission parameters to send data to the network device. Unauthorization is also known as configured grant (CG). Compared with the traditional "request-authorization"-based uplink data transmission method, the uplink unlicensed transmission can effectively reduce the signaling overhead because the network device does not need to send the authorization, and the uplink unauthorized transmission can be significant because it does not need to wait for the authorization of the network device. Reduce data transmission delay. Uplink unlicensed transmissions can be applied to the transmission of bursty, delay-sensitive small packets.

In order for the terminal device to transmit uplink data using the uplink unlicensed transmission method, the network device needs to allocate a transmission resource (hereinafter referred to as an unlicensed transmission resource) required for the terminal device to transmit data in an unauthorized manner. The parameters of the unlicensed transmission resource include: period P, time domain resource offset parameter, time domain resource allocation, frequency domain resource allocation, UE specific demodulation reference signal configuration information, MCS, repetition number, power control parameter, and redundancy version. (redundancy version, RV) sequence.

Upstream unlicensed transmissions can be classified into two types according to different resource configuration methods: configured authorization type 1 (configured grant type 1) and configured authorization type 2 (configured grant type 2). The difference between the two types is that, for the configured authorization type 1, only the radio resource control (RRC) signaling is used to configure the unlicensed resource, and the downlink control information (DCI) is not needed for the resource. Configuration; for the configured authorization type 2, RRC signaling and DCI need to be used to configure the exempted resources, where RRC signaling can be used to configure the RV sequence and period P, and DCI can be used to activate/deactivate the unlicensed transmission and configuration. The time-frequency domain resource of the unlicensed transmission, the terminal device can use the configured unlicensed transmission resource only after receiving the DCI.

The channel used by the terminal device for the unlicensed transmission is the PUSCH, and the configuration of the unlicensed transmission resource needs to use the RRC signaling. Therefore, the channel used by the terminal device to transmit data in an unlicensed manner is called the PUSCH of the upper layer configuration. The higher layer configured PUSCH) may also be referred to as a PUSCH (configured grant PUSCH), and the unlicensed transmission is referred to as a higher layer configured transmission.

In the 5GNR, the unlicensed resource allocated for a terminal device may be: in a period P, K transmission occasions (TO) are configured, and the time domain resource size occupied by the K TOs is less than or equal to the period P. The size of the time domain resource within. The time unit of the period P may be a time slot or a time domain symbol, or may be a subframe or a radio frame; each TO may be used for one transmission of a transmission block (TB), and K of the period P The TO can be used for up to K transmissions of the TB. Since only one TB is transmitted in one cycle P, the corresponding K transmissions of the TB are also referred to as K repetitions of the TB. The different transmissions of the TB can use the same redundancy version or different redundancy versions. The RV used by the terminal device to send the TB once using a certain TO is determined by the index of the TO in the period. Specifically, the RV used by the nth TO in the period P is the first in the configured RV sequence (mod (n-1, 4) + 1) RVs, where mod represents the modulo operation, 1 <= n <= K. The time domain resource size occupied by a TO is determined according to the time domain resource allocation parameter.

5G NR supports two TO configurations, one can be called slot-based TO configuration, that is, there is at most one TO in a slot, as shown in Figure 10A, where P is 8 slots and K is 4 Another can be called a non-slot-based TO configuration, that is, there can be multiple TOs in one slot, as shown in FIG. 10B, P is 2 slots, that is, 28 time domain symbols. K is 4, and each TO occupies 2 time domain symbols. The time domain symbol in the present application may be an orthogonal frequency division multiplexing (OFDM) symbol, or may be a discrete Fourier transform spread OFDM (DFTS-OFDM). )symbol.

When the terminal device has a data packet to be sent to the network device, use the TO configured by the network device to perform repeated transmission of the unauthorized data according to the following rules: (1) when the configured RV sequence is {0, 2, 3, 1} The first transmission of the data packet can start on the first TO in the period P; (2) when the configured RV sequence is {0, 3, 0, 3}, the first transmission of the data packet can be RV in the period P. Start on TO associated with 0; (3) When the configured RV sequence is {0000}, if K is equal to 8, the first transmission of the data packet can start on the other TO except the last TO in the period P; If K is 1, 2 or 4, the first transmission of the packet can begin on all K TOs in period P; (4) for any RV sequence, when one of the following conditions is met, the transmission of the packet That is, it is terminated: the number of transmissions reaches K times or the transmission of the packet on the last TO of the K TOs in the period P is completed.

When the terminal device uses the above rules to send data packets, it can use up to K TOs in the period P for repeated transmission, and the HARQ process identifier used to send the data packets can be based on the starting symbols of the first TO of the K TOs in the period. Index to calculate. In this way, even if the network device fails to detect all the repeated transmissions of the data packet due to channel fading or the like, the unique symbol of the first TO of the K TOs in the period in which the repetition is detected may be determined to be unique. The HARQ process identifier does not cause the terminal device and the network device to have different understandings of the HARQ process identifier, resulting in data confusion.

The terminal device can send uplink control information (UCI) in two ways. One is that the UCI is carried in the PUCCH, and the UCI is transmitted using the resources of the PUCCH; the other is that the UCI is carried in the PUSCH, and the UCI is transmitted using the resources of the PUSCH.

The terminal device uses the semi-static unlicensed resource configured by the network device to perform data transmission in an unauthorized manner, and has high requirements on delay and reliability of data transmission. When the transmission resources of UCI and the transmission resources of the unlicensed data partially overlap or completely overlap in the time domain, sending UCI in the overlapping area may affect the reliability of the unauthorized data transmission; when the UCI transmission resource and the unauthorized data When the transmission resources partially overlap or completely overlap in the time domain, if the UCI is not always transmitted in the overlapping area, the downlink data transmission of the terminal device is affected. Therefore, the technical problem to be solved is that when the transmission resources of the UCI and the transmission resources of the unlicensed data partially overlap or completely overlap in the time domain, the impact of the transmission of the UCI on the reliability of the unauthorized data transmission is minimized.

In the embodiment of the present application, when the transmission resource of the UCI and the transmission resource of the PUSCH configured by the upper layer partially overlap or completely overlap in the time domain, a method for whether the terminal device sends the UCI on the PUSCH is given. FIG. 10C is a schematic flowchart diagram of an uplink information transmission method according to an embodiment of the present application.

S1011. The terminal device determines information of a PUSCH configured by a high layer.

Specifically, the information of the PUSCH of the high layer configuration includes at least one of an RV sequence used in the PUSCH transmission of the upper layer, a period P, a number K of TOs in the period P, and an MCS used in the PUSCH transmission of the high layer configuration. Here, "at least one" refers to any one of the above listed information, or a combination of any two of the information, or a combination of any two or more of the above.

Optionally, the method for the terminal device to determine the information of the PUSCH configured by the upper layer includes: for the configured authorization type 1, the terminal device receives the RRC signaling for configuring the PUSCH from the network device, and determines the upper layer according to the received RRC signaling. The configured PUSCH information; for the configured authorization type 2, the terminal device receives the RRC signaling for configuring the PUSCH from the network device, and determines the RV sequence and the period P used by the PUSCH transmission configured by the upper layer according to the received RRC signaling. And the number K of TOs in the period P; for the configured authorization type 2, the terminal device receives the DCI from the network device, and determines the MCS used by the PUSCH transmission configured by the upper layer according to the received DCI.

Further, the terminal device may determine, according to the period P, the number K of TOs in the period P, and the time domain location where the PUSCH transmission of the upper layer configuration is located, the number of TO used in the PUSCH transmission of the high layer configuration in the K TOs in one cycle. n (1 <= n <= K). The terminal device can determine the RV used by the nth TO according to the number n and RV sequence of the TO. The terminal device may determine the code rate used by the PUSCH transmission of the high layer configuration according to the MCS used by the PUSCH transmission configured by the higher layer.

S1012: When the second condition is established, the terminal device sends uplink data to the network device on the PUSCH configured in the upper layer, and does not send the UCI on the PUSCH configured in the upper layer. The transmission resource of the UCI and the transmission resource of the PUSCH configured by the upper layer partially overlap or completely overlap in the time domain. In the embodiment of the present application, there may be two different implementation manners for transmitting UCI on the PUSCH. One is that the UCI uses the transmission resource of the PUSCH for transmission, and the PUSCH data mapped to the transmission resource used by the UCI is punctured; The other is that UCI uses the transmission resources of the PUSCH for transmission, and the PUSCH data is mapped to resources other than the transmission resources used by the UCI.

Specifically, the second condition may be any one of the following conditions:

(1) The RV used for the PUSCH transmission of the high layer configuration is 0 or 3. Since the RV takes a value of 0 or 3, the success rate of decoding the data transmitted through the TO is higher, and the reliability of the data transmission when the RV values are 0 and 3 should be preferentially ensured. Therefore, the RV value is not used. The UCI is transmitted on the PUSCH of the high layer configuration corresponding to 0 or 3.

(2) The TO used in the PUSCH transmission of the higher layer configuration is greater than or equal to the threshold K1 in all TOs in the period. Optionally, the terminal device determines the threshold K1 according to the number K of TOs in the period P, for example, K1=ceil(K/2), and the ceil represents a rounding operation.

(3) The coding rate R used by the PUSCH transmission of the higher layer configuration is greater than or equal to the threshold R1. The coding rate may be the coding rate indicated by the network device by the signaling, or may be the coding rate determined by the terminal device according to the transmission block size and the time-frequency domain resource size used by the PUSCH transmission configured by the upper layer, or may be after the HARQ combination. The resulting encoding rate. The threshold R1 may be specified by the protocol, or may be indicated by the network device to the terminal device through RRC signaling or DCI or MAC CE. When the coding rate R is greater than or equal to the threshold R1, for example, the value of R1 may be 0.3, indicating that the current data transmission rate is already relatively high. If the UCI reuses a part of the transmission resources of the PUSCH, the transmission quality of the PUSCH may further deteriorate. . Therefore, in order to improve the reliability of the PUSCH transmission, when the coding rate R is greater than or equal to the threshold R1, the UCI is not transmitted on the PUSCH of the higher layer configuration.

(4) The number of transmissions n2 of the TB of the PUSCH transmission of the high layer configuration is less than or equal to the threshold K2. The number of transmissions n2 here is used to characterize that the transmission of the TB on the current TO is the nth transmission of the TB. Optionally, the terminal device may determine the threshold K2 according to the number K of TOs in the period P, for example, K2=ceil(K/2). For the first K2 transmission of the TB in the period P, since the number of times the TB is transmitted is small, in order to reduce the transmission delay of the TB, the TB is correctly decoded by the network device in the shortest possible time, so avoid The UCI occupies the transmission resources of the PUSCH configured by the upper layer. When the network device detects a missed transmission of the TB, the network device's understanding of the number of transmissions of the TB may be inconsistent with the actual number of transmissions of the TB, thereby causing the network device to determine the second condition and the terminal device is inconsistent. The network device is determined to have an error in whether or not the UCI is transmitted on the PUSCH. In order to avoid the above-mentioned erroneous determination, when the UCI is transmitted on the PUSCH, the terminal device may transmit, to the network device, indication information indicating that the UCI is transmitted on the PUSCH. Specifically, whether UCI is transmitted on the PUSCH may be indicated by using different reference signals. For example, the network device receives the first reference signal, indicating that the UCI is not transmitted on the PUSCH; and the network device receives the second reference signal, indicating that the UCI is transmitted on the PUSCH; wherein, the first reference signal and the second reference signal are The reference signal sequence used is different.

(5) In the case that the transmission of the UCI is triggered by the DCI sent by the network device, the last time domain symbol occupied by the DCI is between the UCI and the first symbol of the PUSCH time domain resource overlapped by the high layer configuration. The number of symbols n3 is less than or equal to the threshold K3. Optionally, the threshold K3 may be specified by the protocol, or may be indicated by the network device to the terminal device by using RRC signaling or DCI or MAC CE. For example, K3 may be equal to the PUSCH preparation time.

(6) The MCS table corresponding to the PUSCH is the first MCS table. Specifically, the first MCS table may be one or more of a plurality of MCS tables configured for uplink data transmission, and the spectrum efficiency corresponding to the MCS index with the lowest spectral efficiency in the first MCS table. Is the lowest of multiple MCS tables. Optionally, when the first parameter corresponding to the PUSCH is the first preset value, for example, the RRC parameter “mcs-table” in the NR protocol takes the value “qam64LowSE”, the MCS table corresponding to the PUSCH is the first. MCS form.
