In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description is given of related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as an alternative, which all belong to the protection scope of the embodiments of the present application.

In R16 URLLC enhanced (enhancement), in order to guarantee high priority data preferentially, e.g. uplink feedback of URLLC adopts separate transmission of high priority and low priority uplink feedback, and when the two conflict, the transmission of high priority uplink feedback is prioritized, and the low priority uplink feedback is discarded.

In R17 URLLC enhancement, in order to minimize loss caused by loss of low priority uplink feedback, when high priority and low priority uplink feedback conflict, multiplexing transmission is adopted by the high priority and low priority uplink feedback, and different transmission code rates are adopted, so that reliability of respective priorities and overall transmission efficiency are ensured.

Currently, the transmit power of the uplink control channel is determined by the maximum output power, the target receive power, the number of physical resource blocks (Physical Resource Block, PRBs) of the uplink control channel, the downlink path loss estimation, the offset for different physical uplink control channel (Physical Uplink Control Channel, PUCCH) formats, the power adjustment amount corresponding to the PUCCH equivalent code rate, and the closed loop adjustment amount of the uplink control channel. Here, the uplink control channel may be PUCCH.

In the case that the PUCCH, the Bandwidth Part (BWP) of the Bandwidth where the PUCCH is located, the carrier where the PUCCH is located, and the primary cell where the PUCCH is located are determined, the transmit power of the PUCCH may be calculated based on equation (1):

wherein P is _CMAX,f,c (i) Is maximum output power, P _{O_PUCCH,b,f,c} (q _u ) Is the target received power, q _u Is the target received power index of the uplink reference signal;the number of PRBs of the uplink control channel; PL (PL) _b,f,c (q _d ) Is the downlink loss estimation, q _d Is the index of the downlink reference signal; delta _{TF_PUCCH} (F) Offset for different PUCCH formats, F is the format of the uplink control channel; delta _TFb,f,c (i) The power adjustment amount for the PUCCH equivalent code rate; g _b,f,c (i, l) is the closed loop adjustment amount of the uplink control channel, and l is the power control adjustment index; f is the carrier wave where the uplink control channel is located, c is the primary cell where the uplink control channel is located, b is the BWP where the uplink control channel is located, and i is the PUCCH transmission opportunity index.

Wherein, for the power adjustment quantity of PUCCH equivalent code rate, delta _TFb,f,c (i) For PUCCH format (format) 2 or format 3 or format 4, the equivalent code rate determination based on uplink control information (Uplink Control Information, UCI) transmitted by the PUCCH. Here, the equivalent code rate of UCI is the transmission code rate of UCI, that is, the code rate adopted in transmission.

Δ _TFb,f,c (i) The determination mode of (2) comprises the following steps:

if the UCI bit number is less than or equal to 11, the power adjustment amount delta for PUCCH equivalent code rate _TFb,f,c (i) Is calculated by the formula (2),

Δ _TFb,f,c (i)＝10log ₁₀ (K ₁ * BPRE (i)) formula (2);

wherein K is ₁ =6, bit per resource element (Bit Per Resource Element, BPRE) (i) is equivalent code rate, BPRE (i) = (O) _HARQ-ACK (i)+O _SR (i)+O _CSI (i))/N _RE (i)，O _HARQ-ACK For the number of hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat-reQuest Acknowledgement, HARQ-ACK) information bits in UCI, O _SR For the number of scheduling request (Scheduling Request, SR) information bits in UIC, O _CSI For the number of channel state information (Channel State Information, CSI) information bits, N in UCI _RE Number of Resource Elements (RE) occupied by UCI, N _RE (i) Can be calculated based on formula (3):

for the number of carriers occupied by UCI,the number of symbols occupied by UCI.

If the UCI bit number is greater than 11, the power adjustment amount delta for PUCCH equivalent code rate _TFb,f,c (i) Calculated by the formula (4):

Δ _TFb,f,c (i)＝10log ₁₀ (2 ^k2*BPRE(i) -1) formula (4);

wherein K is ₂ =2.4, BPRE (i) is the equivalent code rate, and BPRE (i) can be calculated based on formula (5):

BPRE(i)＝(O _HARQ-ACK (i)+O _SR (i)+O _CSI (i)+O _CRC (i))/N _RE (i) Equation (5);

O _HARQ-ACK (i) For the number of HARQ-ACK information bits in UCI, O _SR (i) For the number of SR information bits in UIC, O _CSI (i) For the number of CSI bits in UCI, O _CRC (i) For the number of cyclic redundancy check (Cyclic Redundancy Check, CRC) bits corresponding to UCI, N _RE (i) For the number of resource elements occupied by UCI, N _RE (i) Can be determined based on equation (3).

In the above scheme, delta _TFb,f,c (i) Is an adjustment amount for PUCCH equivalent code rate. In R15/16, only one transmission code rate is adopted by one control channel, and the transmission code rate corresponds to the PUCCH equivalent code rate. However, the introduction of R17 into an uplink control channel includes multiple transmission code rates, for example, high priority information corresponds to a first code rate, low priority information corresponds to a second code rate, and the existing PUCCH equivalent code rate cannot correspond to any information, and cannot adapt to an appropriate power adjustment amount.

The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

An optional processing flow of the wireless communication method provided in the embodiment of the present application, as shown in fig. 2, includes the following steps:

S201, the terminal equipment determines a target power adjustment amount of a first uplink control channel.

The target power adjustment amount is determined based on a first power adjustment amount and a second power adjustment amount, the first power adjustment amount is a power adjustment amount corresponding to first uplink control information, the second power adjustment amount is a power adjustment amount corresponding to second uplink control information, the first uplink control channel is used for multiplexing transmission of the first uplink control information and the second uplink control information, and the priority of the first uplink control information is different from the priority of the second uplink control information.

Here, when determining that the first uplink control channel is multiplexed to transmit the first uplink control information and the second uplink control information, the terminal device determines a first power adjustment amount corresponding to the first uplink control information and a second power adjustment amount corresponding to the second uplink control information, and determines a target power adjustment amount of the first uplink control channel based on the first power adjustment amount and the second power adjustment amount. The first uplink control channel is used for multiplexing uplink control channels for transmitting the first uplink control information and the second uplink control information.

Optionally, the uplink control channel is PUCCH.

Optionally, the target power adjustment is used to determine the transmit power of the first uplink control information.

After determining the target power adjustment amount, the terminal device determines the transmitting power of the first uplink control channel based on the target power adjustment amount, and sends the first uplink control information and the second uplink control information on the first uplink control based on the determined transmitting power.

The network equipment receives first uplink control information and second uplink control information which are transmitted by the terminal equipment through multiplexing, wherein target power adjustment amounts corresponding to the first uplink control information and the second uplink control information are determined based on the first power adjustment amount and the second power adjustment amount, the first power adjustment amount is the power adjustment amount corresponding to the first uplink control information, and the second power adjustment amount is the power adjustment amount corresponding to the second uplink control information.

Optionally, the priority of the first uplink control information and the priority of the second uplink control information are different.

In an example, the first uplink control information has a higher priority than the second uplink control information.

In an example, the priority of the first uplink control information is lower than the priority of the second uplink control information.

In this embodiment, when the first uplink control information and the second uplink control information are multiplexed and transmitted through the first uplink control channel, the target power adjustment amount of the first uplink control channel may be determined based on the first power adjustment amount corresponding to the first uplink control information and the second power adjustment amount corresponding to the second uplink control information, so that the power adjustment amount of the first uplink control channel is determined based on the power adjustment amounts corresponding to the plurality of uplink control information transmitted by the first uplink control channel, and is a power adjustment amount suitable for the first uplink control channel.

In this embodiment of the present application, the priority of the uplink control information may be determined based on at least one of the following attribute parameters: service type, service reliability requirements and transmission delay requirements. The traffic types may include: enhanced mobile broadband (emmbb), mass machine type communication (mctc), uirllc, and the like. The reliability requirements of a service may be characterized by different reliability identifications, such as: the reliability requirements include: the first-level reliability, the second-level reliability and the third-level reliability are orderly sequenced from high to low according to the reliability: first-level reliability, second-level reliability and third-level reliability. The transmission delay requirement of the service can be characterized by different delay identifications, such as: the transmission delay requirements include: the first-level time delay, the second-level time delay and the third-level time delay are sequentially ordered from high to low, and the time delay requirements are as follows: first-level delay, second-level delay and third-level delay.

Alternatively, when the prioritized property parameter includes a class of property parameters, the information priority of the PUCCH or PUSCH may be determined according to the level of the current property parameter.

In an example, if the delay requirement of the first uplink control information is higher than the delay requirement of the second uplink control information, the priority of the first uplink control information is higher than the priority of the second uplink control information.

In an example, if the delay requirement of the first uplink control information is lower than the delay requirement of the second uplink control information, the priority of the first uplink control information is lower than the priority of the second uplink control information.

Alternatively, when the prioritized property parameter includes a multi-class property parameter, the information priority of the PUCCH or the information priority of the PUSCH may be determined according to the plurality of property parameters. In an example, when the attribute parameter includes multiple types of attribute parameters, the levels corresponding to the different attribute parameters are determined, and the quantization results of the multiple levels are weighted and summed to obtain the information priority of the PUCCH or PUSCH. In yet another example, when the attribute parameters include multiple types of attribute parameters, a level corresponding to each attribute parameter is determined, and a highest level is determined as an information priority of a corresponding channel.

In the wireless communication method shown in fig. 2, the first uplink control information and the second uplink control information, which are two pieces of uplink control information having different priorities, are multiplexed on the first uplink control channel, and in practical application, the wireless communication method shown in fig. 2 is simultaneously applicable to a scenario in which three or more pieces of uplink control information having different priorities are multiplexed on the same uplink control channel, that is, the first uplink control channel.

Optionally, the at least two uplink control information includes first uplink control information and second uplink control information, and the at least two power adjustment amounts include a first power adjustment amount and a second power adjustment amount.

In an example, the first uplink control channel multiplexes uplink control information 1, uplink control information 2 and uplink control information 3, and priorities of the uplink control information 1, the uplink control information 2 and the uplink control information 3 are different, the power adjustment amount corresponding to the uplink control information 1 is the power adjustment amount 1, the power adjustment amount corresponding to the uplink control information 2 is the power adjustment amount 2, the power adjustment amount corresponding to the uplink control information 3 is the power adjustment amount 3, and then the target power adjustment amount of the first uplink control channel is determined based on the power adjustment amount 1, the power adjustment amount 2 and the power adjustment amount 3.

In some embodiments, when determining that the second uplink control channel and the third uplink control channel overlap in time domain, the terminal device determines to multiplex the first uplink control channel to transmit the first uplink control information and the second uplink control information, where the second uplink control channel is used to transmit the first uplink control information, and the third uplink control channel is used to transmit the second uplink control information.

Optionally, the code rate of the first uplink control information and the code rate of the second uplink control information, that is, the equivalent code rate, are determined independently.
