Detailed Description

As described in the background, the related art does not consider a problem of how to allocate transmission power between respective channels when a UE simultaneously transmits a plurality of channel information on a direct link.

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

"simultaneous transmission" as used herein refers to overlapping or partially overlapping in time between the time-frequency resources of the bearer channel or overlapping or partially overlapping in time and frequency domain between the time-frequency resources of the bearer channel.

It should be noted that, herein, the "Priority of the physical direct link shared channel (Physical Sidelink Shared Channel, abbreviated as PSSCH)" may be determined by a near field communication data Packet Priority (ProSe Per-Packet Priority, abbreviated as PPPP) corresponding to a transmission carried by the PSSCH, and a lower value of PPPP means a higher Priority of the corresponding transmission, and PPPP may be indicated by SCI (Sidelink Control Information, abbreviated as direct link control information) or higher layer signaling. The value of PPPP may be related to at least one parameter of QoS priority (priority), latency (latency), reliability (reliability) and minimum required communication distance (minimum required communication range).

Fig. 1 is a flow chart of a method for allocating transmit power according to an embodiment of the present invention. The allocation method may be performed by a terminal, for example by an NR V2X UE. Specifically, the allocation method may include the steps of:

Step S101, when control information is sent on a plurality of channels of a direct link, determining the arrangement sequence of the channels;

step S102, according to the arrangement sequence, the transmitting power of each channel is allocated in turn.

Wherein the control information may include one or more of: hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback information, channel state information (Channel State Information, CSI), scheduling request (Scheduling Request, SR) information.

The HARQ feedback information includes ACKnowledgement/negative ACKnowledgement (ACK/NACK).

CSI may include one or more of the following: channel quality Indication (Channel Quality Indicator, CQI), precoding matrix Indication (Precoding Matrix Indicator, PMI), rank Indication (RI), reference signal received power (Reference Signal Receiving Power, RSRP), received signal strength Indication (Received Signal Strength Indicator, RSSI), signal-to-noise-and-interference ratio (Signal to Interference plus Noise Ratio, SINR), CSI-reference-signal Resource Indicator, CRI), synchronization signal block resource Indication (Synchronization Signal Block resource indicator, SSBRI). Wherein, the reference signal received power may be a physical layer RSRP (i.e., L1-RSRP) and the received signal strength indication may be a physical layer RSSI (i.e., L1-RSSI).

The plurality of channels may all be a plurality (Physical Sidelink Feedback CHannel, abbreviated PSFCH) of channels. Alternatively, the plurality of channels may be a plurality of PSFCH channels and a plurality of passable PSSCH channels. Still alternatively, the plurality of channels may be a plurality of PSFCHs, a plurality of PSSCHs, and a physical direct link control channel (Physical Sidelink Control CHannel, abbreviated PSCCH). Still alternatively, the plurality of channels may be a plurality of PSFCHs and a plurality of physical direct link discovery channels (Physical Sidelink Discovery CHannel, abbreviated PSDCH), etc.

In step S101, if the UE needs to transmit a plurality of control information on a plurality of channels of the direct link together, in order to determine the transmit power of each channel, the arrangement order of the plurality of channels may be determined, so as to allocate the transmit power of each channel to the UE with a constant total transmit power.

As a specific embodiment, if the control information is the same control information and the plurality of channels are PSFCHs, the arrangement order of the PSFCHs may be determined according to the priorities of the PSSCHs associated with the PSFCHs. For example, when there are a plurality of PSFCHs, one of the PSFCHs has the highest priority of the PSSCH associated therewith, its transmit power is preferentially allocated in the power allocation. For the remaining PSFCHs, the transmit power thereof may be allocated in order of priority from high to low, and so on.

Wherein the priority related information of the PSSCH can be carried by a PSCCH which schedules the PSSCH. The priority related information may be carried in a display, or may implicitly indicate, for example, a latency requirement (latency requirement) of data transmitted through the PSSCH, which implicitly indicates the priority of each PSSCH.

Wherein, if the priorities of the PSSCHs corresponding to the PSFCHs are the same, the PSFCH is determined to be allocated with the transmission power of the PSFCH preferentially according to the UE implementation.

As a non-limiting example, when the priorities of the PSSCHs associated with the respective PSFCHs are the same, the UE may randomly generate the ranking of the respective PSFCHs and determine the ranking of the respective PSFCHs. Alternatively, the UE may determine the arrangement order of the PSFCHs according to the resource index value of the resources occupied by the PSFCHs. In the specific implementation, the resource index values may be arranged in the order from small to large, or may be arranged in the order from large to small.

As yet another non-limiting example, if the control information is the same control information and the plurality of channels are all PSFCHs, the arrangement order of the respective PSFCHs may be determined according to the communication distance (communication range) of the data transmitted by the respective PSFCHs.

In a specific implementation, the arrangement order of the PSFCHs may be determined in order of the communication distance from small to large or in order of the communication distance from large to small, and the transmission power of each PSFCH may be allocated according to the arrangement order.

Wherein the communication distance may be a specific communication distance. In practical applications, the communication distance may also be represented according to the RSRP or RSSI value of the reference signal. The reference signal may be a demodulation reference signal (De-Modulation Reference Signal, abbreviated as DMRS) of the PSFCH, or a DMRS of a PSSCH associated with the PSFCH, or a DMRS of a scheduling PSCCH corresponding to the PSSCH associated with the PSFCH, or a channel state indication reference signal (Channel State Indicator Reference Signal, abbreviated as CSI-RS) of an associated direct link, or a synchronization signal block (Synchronization Signal and physical broadcast channel Block, abbreviated as SSB) of the associated direct link.

As a variation, the communication distance may also be expressed according to the RSRP or RSSI value of the channel. The channel may be a PSFCH, or a PSSCH associated with a PSFCH, or a scheduled PSCCH corresponding to a PSSCH associated with a PSFCH. The higher the RSRP or the RSSI value, the closer the corresponding communication distance is, and otherwise, the farther the corresponding communication distance is.

Wherein, if there are a plurality of PSFCHs corresponding to the same communication distance, depending on the UE implementation, it is decided which PSFCHs are preferentially allocated to transmit power.

As a non-limiting example, the UE may randomly generate the permutation order of the PSFCHs when the communication distances of the data transmitted by the PSFCHs are the same. Alternatively, the UE may determine the arrangement order of the PSFCHs according to the resource index value of the resources occupied by the PSFCHs.

As yet another non-limiting example, if the control information is the same control information and the plurality of channels are all PSFCHs, the arrangement order of the PSFCHs may be determined according to a data transmission manner of the PSSCH associated with each PSFCH, wherein the data transmission manner may be selected from unicast, multicast, and broadcast.

In an implementation, the UE may first determine a data transmission manner of the PSSCH associated with each PSFCH. Then, the arrangement sequence of each PSFCH can be determined according to the data transmission mode.

For example, the data transmission mode includes only unicast and multicast, and at this time, the UE may order the PSFCH associated with the PSSCH of the multicast transmission data before the PSFCH associated with the PSSCH of the unicast transmission data, and order the PSFCH associated with the PSSCH of the multicast transmission data after the PSFCH associated with the PSSCH of the unicast transmission data, that is, preferentially allocate the transmit power of the PSFCH associated with the PSSCH of the multicast transmission data. Conversely, the UE may order the PSFCH associated with the PSSCH of the unicast data before and the PSFCH associated with the PSSCH of the multicast data after, i.e., allocate the transmit power of the PSFCH associated with the PSSCH of the unicast data preferentially.

In a specific implementation, when the data transmission modes of the PSSCHs associated with the PSFCHs are the same, the UE may randomly generate the permutation sequence of the PSFCHs, and determine the permutation sequence of the PSFCHs. As a variation, the UE may further determine the arrangement order of the PSFCHs according to the resource index value of the resources occupied by each PSFCH. The PSFCH occupies the resources with smaller resource index values can be ordered before, namely, the transmitting power of the PSFCH with smaller resource index values is preferentially allocated; alternatively, the PSFCH may occupy resources with larger resource index values in the order before, i.e., transmit power of the PSFCH with smaller resource index value is preferentially allocated.

As another variation, the UE may also determine the permutation sequence of the PSFCHs according to the first symbol (symbol) or the first slot (slot) of the resources occupied by each PSFCH. In a specific implementation, the PSFCH of the first symbol or first slot of the resources occupied by the PSFCH may be ordered before (i.e., the transmission power of the PSFCH of the first symbol or first slot is preferentially allocated).

In an implementation, if there is a first symbol or a first slot of a plurality of PSFCHs that is the same, the time domain lengths of the PSFCHs may be compared, and the PSFCHs with longer time domain lengths are ordered first, i.e., the transmit power of the PSFCHs with longer time domain lengths are preferentially allocated. Alternatively, if there is a first symbol or a first slot of a plurality of PSFCHs that is the same, the time domain lengths of the PSFCHs may be compared, and the PSFCHs with shorter time domain lengths are ordered first, i.e., the transmit power of the PSFCHs with shorter time domain lengths are preferentially allocated.

In an implementation, if there is a first symbol or a first slot of a plurality of PSFCHs that are the same and the time domain lengths of the PSFCHs are the same, the UE may randomly select the rank of the PFSCH and sequentially allocate the transmit power of the PSFCHs according to the random rank.

As another variation, the UE may further determine the permutation sequence of the PSFCHs according to the first symbol (symbol) or the first slot (slot) of the time-frequency resource occupied by the PSSCH associated with each PSFCH. The PSFCH of the first symbol or first slot of the resources occupied by the PSSCH associated with the PSFCH may be ordered first, i.e., the transmit power of the PSFCH of the first symbol or first slot of the associated PSSCH is preferentially allocated. As another non-limiting example, if the control information is different control information and the plurality of channels are all PSFCHs, the UE may first determine the arrangement order of the various control information, and then the UE may determine the arrangement order of the feedback channels of the respective physical direct links according to the arrangement order of the various control information.

In an implementation, if there are multiple PSFCHs associated with the same first symbol or first slot of the time-frequency resource occupied by the PSSCH, the time-domain lengths of the PSSCHs may be compared, and the PSSCH with the longer time-domain length is ordered first, i.e., the transmit power of the PSFCH with the first symbol or first longer time-domain length of the associated PSSCH is preferentially allocated. Alternatively, if there is a first symbol or a first slot of the plurality of PSSCHs that is the same, the time-domain lengths of the PSSCHs may be compared, and the PSSCHs with shorter time-domain lengths are ordered first, i.e., the transmit power of the first symbol or the first PSFCH with shorter time-domain length of the associated PSSCH is preferentially allocated.

In an implementation, if there are the first symbols or the first time slots of the time-frequency resources occupied by the PSSCHs associated with the PSFCHs are the same, and the time domain lengths of the PSSCHs are the same, the UE may randomly select the rank of the PFSCHs, and sequentially allocate the transmit power of the PSFCHs according to the random rank.

In implementations, the priorities of the various different control information may be predefined. As one non-limiting example, the control information includes SR information, HARQ feedback information, and CSI. The SR information, the HARQ feedback information, and the priority of the CSI may be predefined to decrease in order. Alternatively, the priority of the HARQ feedback information, the SR information, and the CSI may be predefined to be sequentially lowered. Alternatively, the HARQ feedback information, the priority of CSI, and the SR information may be predefined to decrease sequentially. Alternatively, the SR information, the HARQ feedback information, and the priority of the CSI may be predefined to decrease sequentially. Alternatively, the priority of the CSI, the HARQ feedback information, and the SR information may be predefined to be sequentially lowered. Alternatively, the priority of the CSI, the SR information, and the HARQ feedback information may be predefined to be sequentially lowered. Thereafter, the arrangement order of the various control information may be determined according to priorities of the various control information defined in advance.

As still another specific embodiment, the plurality of channels are different types of channels, and at this time, the UE may first determine the arrangement order of the different types of channels, and then determine the arrangement order of the feedback channels of the respective physical direct links according to the arrangement order of the different types of channels. Wherein, the different types of channels may include at least two of: PSFCH, PSSCH, PSCCH, PSDCH.

In step S102, the UE may sequentially allocate the transmit power of each channel according to the arrangement order of the plurality of channels.

Taking the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports transmission of HARQ feedback information and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (e.g., in the same time slot), the rank order of the PSFCHs may be determined according to the priority of the PSSCH corresponding to the PSFCH, and the transmit power of the PSFCH with a high priority may be preferentially allocated.

In a specific implementation, it is assumed that there are M PSFCHs, where M is a positive integer greater than 1, PSFCH1 is N1, PSFCH2 is N2, PSSCH2, … …, PSFCHn is Nn, and PSSCHn is N1, N2 …, nn, N are positive integers. N1+n2+ … … +nn=m. And the priorities of PSSCH1, PSSCH2, … … and PSSCH Hn are sequentially decreased. At this time, the UE may preferentially allocate the transmit powers of the N1 PSFCHs 1, and then sequentially allocate the transmit powers of the PSFCHs 2, … …, and PSFCHn. For each PSFCH1 or PSFCH2 or other PSFCH, power allocation may be performed according to the following similar method technical scheme, which is not expanded here.

In an implementation, it is assumed that there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 has a higher priority than PSSCH2. At this time, the UE may preferentially allocate the transmit power of the PSFCH 1. Let P be _PSFCH1 The transmit power of PSSCH1 is indicated, and the transmit power of the channel PSSCH1 can be determined in accordance with existing protocols and will not be discussed in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX –P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, P _typical Representing at least the transmit power associated with the number of frequency domain resources of the PSFCH 1. Specifically, P _CMAX The maximum transmit power of the user equipment on the element carrier (component carrier) may be represented. And P _typical The parameters related to the transmit power value of (a) may include at least the frequency domain resource number (e.g., the number of resource blocks and/or the number of sub-channels, etc.) of the PSFCH1, and/or the path loss of the direct link of the UE, etc.

And continuing taking the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports transmission of HARQ feedback information and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (e.g., in the same time slot), the rank order of the PSFCHs may be determined according to the communication distance of the data transmitted by the PSFCHs, and the transmit power of the PSFCH with high priority may be preferentially allocated. Note that, the communication distance may refer to an actual communication distance, or may refer to a communication distance represented by RSSI or RSRP, and reference is made to the foregoing, and details are not repeated here.

In a specific implementation, it is assumed that there are two PSFCHs, where the communication distance corresponding to the PSFCH1 is greater than the communication distance corresponding to the PSFCH2, and the transmission powers are allocated in the order of the communication distances from the large to the small, where the transmission powers of the PSFCH1 may be allocated preferentially. Let P be _PSFCH1 The transmit power of the PSFCH1 is indicated, and the transmit power of the channel PSFCH1 may be determined according to an existing protocol and will not be described in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX Can represent the maximum transmission power of the user equipment on the unit carrier, P _typical Representing at least the transmit power associated with the number of frequency domain resources of the PSFCH 1.

In an implementation, it is assumed that there are two PSFCHs, where PSFCH1 corresponds to a communication distance greater than PSThe communication distances corresponding to FCH2 are allocated, and the transmission power is allocated in the order from the larger communication distance to the smaller communication distance, so that the transmission power of PSFCH1 can be allocated preferentially. Let P be _PSFCH1 The transmit power of the PSFCH1 is indicated, and the transmit power of the channel PSFCH1 may be determined according to an existing protocol and will not be described in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX Can represent the maximum transmission power of the user equipment on the unit carrier, P _typical Representing at least the transmit power associated with the number of frequency domain resources of the PSFCH 1.

In a specific implementation, if there are multiple PSFCHs to be transmitted simultaneously, the UE may preferentially allocate the transmission power of the PSFCH that is ranked before according to the data transmission mode corresponding to the PSSCH associated with the PSFCH.

For example, assume there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 employs multicast transmission and PSSCH2 employs unicast transmission. When the priority of the predefined multicast is higher than the priority of the unicast, the UE may preferentially allocate the transmit power of the PSFCH 1. Let P be _PSFCH1 The transmit power of the PSFCH1 is indicated, and the transmit power of the channel PSFCH1 may be determined according to an existing protocol and will not be described in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX The maximum transmit power of the user equipment on the element carrier may be represented. P (P) _typical Representing a transmit power related to at least the number of frequency domain resources of the PSFCH 1. And P _typical The parameters related to the transmit power value of (a) may include at least the frequency domain resource number (e.g., the resource block number and/or the subchannel number, etc.) of the PSFCH1, and/or the path loss of the direct link of the UE, etc.

For example, assume there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 employs unicast transmissions and PSSCH2 employs multicast transmissions. When the priority of the predefined multicast is lower than that of the unicast, the UE may preferentially allocate the transmit power of the PSFCH 1. Let P be _PSFCH1 The transmit power of the PSFCH1 is indicated, and the transmit power of the channel PSFCH1 may be determined according to an existing protocol and will not be described in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX The maximum transmit power of the user equipment on the element carrier may be represented. P (P) _typical Representing at least the transmit power associated with the number of PSFCH1 frequency domain resources. And P _typical The parameters related to the transmit power value of (a) may include at least the frequency domain resource number (e.g., the resource block number and/or the subchannel number, etc.) of the PSFCH1, and/or the path loss of the direct link of the UE, etc.

In a specific implementation, when the control information is different control information and the plurality of channels are PSFCHs, after the UE determines the arrangement order of the PSFCHs, the UE may sequentially allocate transmit power to the PSFCHs.

As a non-limiting example, if there are multiple PSFCHs to be transmitted simultaneously and the PSFCH carrying CSI has a lower priority than the PSFCH carrying HARQ feedback information, the UE may allocate power to the PSFCH carrying HARQ feedback information preferentially. Those skilled in the art understand that if there are multiple PSFCHs carrying CSI or multiple PSFCHs carrying HARQ feedback information, the foregoing embodiments may be adopted, and will not be repeated here.

For example, assume that there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 carries HARQ feedback information, PSSCH2 carries CSI, and priority of HARQ feedback information is higher than priority of CSI, where transmit power of PSFCH1 may be preferentially allocated. Let P be _PSFCH1 The transmit power of PSSCH1 is indicated, and the transmit power of the channel PSSCH1 can be determined in accordance with existing protocols and will not be discussed in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX The maximum transmit power of the user equipment on the element carrier may be represented. P (P) _typical Representing at least the transmit power associated with the number of frequency domain resources of the PSFCH 1. And P _typical The parameters related to the transmit power value of (a) may include the frequency domain resource number (e.g., the number of resource blocks and/or the number of sub-channels, etc.) of the PSFCH1, and/or the path loss of the direct link of the UE, etc.

For another example, assume that there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 carries CSI, PSSCH2 carries HARQ feedback information, and the priority of the HARQ feedback information is lower than that of CSI, where the transmit power of PSFCH1 may be preferentially allocated. Let P be _PSFCH1 The transmit power of PSSCH1 is indicated, and the transmit power of the channel PSSCH1 can be determined in accordance with existing protocols and will not be discussed in detail here. Thereafter, the UE may allocate transmit power for the PSFCH 2. Work of emission P of PSFCH2 _PSFCH2 Can be min { P } _CMAX -P _PSFCH1 ,P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX Can represent the maximum transmission power of the user equipment on the unit carrier, P _typical Representing at leastIs the transmit power associated with the number of frequency domain resources of the PSFCH 1.

For another example, the control information is different control information including SR information, HARQ feedback information, and CSI, and priorities of the SR information, the HARQ feedback information, and the CSI are sequentially lowered. Assume that there are 3 PSFCHs, PSFCH1, PSFCH2, and PSFCH3, respectively. Wherein PSFCH1 carries the SR information, PSFCH2 carries CSI, and PSFCH3 carries HARQ feedback information. At this time, the UE may first determine the arrangement order of the PSFCHs according to the SR information, the HARQ feedback information, and the priority of the CSI, so as to allocate the transmit power of the PSFCH1 preferentially, then allocate the transmit power of the PSFCH2, and finally allocate the transmit power of the PSFCH3.

In a specific implementation, for the PSFCH2 transmitting the HARQ feedback information, its transmit power is min { P _CMAX -P _PSFCH1 ，P _typical For PSFCH3 transmitting the CSI, the transmission power is min { P }, and _CMAX -P _PSFCH1 -P _PSFCH2 ，P _typical }. Wherein min { P _CMAX -P _PSFCH1 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 、P _typical Min { P } minimum value in (2) _CMAX -P _PSFCH1 -P _PSFCH2 ，P _typical The selection of P is represented by _CMAX -P _PSFCH1 -P _PSFCH2 、P _typical Minimum value of P _CMAX Representing the maximum transmit power of the user equipment, in particular P _CMAX Can represent the maximum transmission power of the user equipment on the unit carrier, P _PSFCH1 Representing the transmit power, P, of the PSFCH1 transmitting the scheduling request information _PSFCH2 Representing the transmit power, P, of the PSFCH2 transmitting the HARQ feedback information _typical Representing at least the transmit power associated with the number of frequency domain resources of the PSFCH 1.

In a specific implementation, the channels for transmitting the same control information may be multiple, for example, there are M1 PSFCHs for transmitting HARQ feedback information, M2 PSFCHs for transmitting SR information, M3 PSFCHs for transmitting CSI information, and M1, M2, and M3 are positive integers greater than 2, where if the priorities of SR, HARQ feedback information, and CSI information are sequentially reduced, the transmission power allocation sequence of each PSFCH is: the transmission power of M2 PSFCHs transmitting the SR is preferentially allocated, then the transmission power of M1 PSFCHs transmitting the HARQ feedback information is allocated, and finally the transmission power of M3 PSFCHs transmitting the CSI information is allocated. For each PSFCH in which the same control information is transmitted, power allocation may still be performed according to the related embodiments of the invention provided herein, which will not be described herein.

Those skilled in the art will understand that the foregoing embodiments may be employed if there are multiple PSFCHs, and will not be repeated here.
