Detailed ways

As mentioned in the background art, the prior art does not consider the problem of how to allocate the transmit power among the channels when the UE transmits multiple channel information simultaneously on the direct link.

An embodiment of the present invention provides a method for allocating transmit power, including: when control information is sent on multiple channels of a direct link, determining an arrangement order of the multiple channels; and sequentially assigning each channel according to the arrangement order. The transmit power of the channel; wherein, the control information includes one or more of the following: HARQ feedback information, channel state information, and scheduling request information. Through the technical solutions provided by the embodiments of the present invention, when the UE needs to send control information on multiple channels, the transmit power can be sequentially allocated based on the determined channel arrangement order, so as to send multiple control information on the direct link at the same time, A feasible solution is provided for allocating the transmit power of each channel to UEs whose total transmit power is constant.

In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The "simultaneous transmission" in this document means that the time-frequency resources of the bearer channel overlap or partially overlap in time, or the time-frequency resources of the bearer channel overlap or partially overlap in time and frequency domain. overlapping.

It should be noted that the "priority of the Physical Sidelink Shared Channel (PSSCH)" that appears in this article can be transmitted through the corresponding proximity communication data packet priority (ProSe Per-Packet) carried by the PSSCH. Priority, referred to as PPPP), the lower the value of PPPP means the higher the priority of its corresponding transmission, PPPP can be indicated by SCI (Sidelink Control Information, referred to as direct link control information) or high-level signaling. The value of PPPP may be related to at least one parameter of QoS priority (priority), delay (latency), reliability (reliability) and minimum required communication range (minimum required communication range).

FIG. 1 is a schematic flowchart of a method for allocating transmit power according to an embodiment of the present invention. The allocation method may be performed by a terminal, eg, by an NR V2X UE. Specifically, the distribution method may include the following steps:

Step S101, when sending control information on multiple channels of the direct link, determine the arrangement order of the multiple channels;

Step S102, according to the arrangement sequence, sequentially assign the transmit power of each channel.

The control information may include one or more of the following: Hybrid Automatic Repeat reQuest (HARQ for short) feedback information, Channel State Information (CSI for short), Scheduling Request (SR for short) )information.

The HARQ feedback information includes acknowledgement/negative acknowledgement (ACKnowledgement/Non-ACKnowledgement, ACK/NACK for short).

The CSI may include one or more of the following: Channel Quality Indicator (CQI for short), Precoding Matrix Indicator (PMI for short), Rank Indication (Rank Indication, RI for short), Reference Signal Received Power (Reference Signal Received Power). Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR), CSI-reference-signal Resource Indicator, CRI for short), synchronization signal block resource indicator (Synchronization Signal Block resource indicator, SSBRI for short). Wherein, the reference signal received power may be physical layer RSRP (ie L1-RSRP), and the received signal strength indicator may be physical layer RSSI (ie L1-RSSI).

The multiple channels may be multiple (Physical Sidelink Feedback CHannel, PSFCH for short) channels. Alternatively, the plurality of channels may be a number of PSFCH channels and a number of pass-through PSSCH channels. Alternatively, the multiple channels may be several PSFCHs, several PSSCHs, and a Physical Sidelink Control CHannel (PSCCH for short). Still alternatively, the multiple channels may be several PSFCHs, several physical sidelink discovery channels (Physical Sidelink Discovery CHannel, PSDCH for short), and the like.

In step S101, if the UE needs to send multiple control information on multiple channels of the direct link at the same time, in order to determine the transmit power of each channel, the arrangement order of the multiple channels may be determined, so as to determine the total transmission power of the multiple channels. A UE with constant power allocates the transmit power of each channel.

As a specific embodiment, if the control information is the same type of control information, and the multiple channels are all PSFCHs, the arrangement order of each PSFCH may be determined according to the priority of the PSSCH associated with each PSFCH. For example, when there are multiple PSFCHs, and the PSSCH associated with one of the PSFCHs has the highest priority, its transmit power is preferentially allocated in power allocation. For the remaining PSFCHs, the transmit power can be allocated in descending order of priority.

The priority-related information of the PSSCH may be carried by the PSCCH, which schedules the PSSCH. The priority-related information may be carried explicitly, or may be implicitly expressed. For example, a latency requirement of data transmitted through the PSSCH implicitly expresses the priority of each PSSCH.

Wherein, if there are multiple PSFCHs corresponding to PSSCHs with the same priority, it depends on the implementation of the UE to determine which PSFCHs transmit power is preferentially allocated.

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

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

In a specific implementation, the arrangement order of each PSFCH may be determined according to the order of communication distance from small to large or the order of communication distance from large to small, and the transmit power of each PSFCH is 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 value of RSRP or RSSI of the reference signal. The reference signal may be a PSFCH demodulation reference signal (De-Modulation Reference Signal, DMRS for short), or a DMRS of a PSSCH associated with the PSFCH, or a DMRS of a scheduled PSCCH corresponding to a PSSCH associated with the PSFCH, or an associated DMRS. The channel state indicator reference signal (CSI-RS for short) of the direct link, or the synchronization signal block (Synchronization Signal and physical broadcast channel Block, SSB for short) of the associated direct link.

As a variant example, the communication distance may also be represented according to the value of RSRP or RSSI of the channel. The channel may be a PSFCH, or a PSSCH associated with the PSFCH, or a scheduled PSCCH corresponding to the PSSCH associated with the PSFCH. Wherein, the higher the value of the RSRP or the RSSI is, the closer the corresponding communication distance is, and vice versa, the longer the corresponding communication distance is.

Wherein, if there are multiple PSFCHs corresponding to the same communication distance, it depends on the implementation of the UE, so as to decide which PSFCH transmit power is allocated preferentially.

As a non-limiting example, when each PSFCH has the same communication distance for data transmission, the UE may randomly generate the arrangement order of each PSFCH. Alternatively, the UE may determine the arrangement order of the respective PSFCHs according to the resource index values of the resources occupied by the respective PSFCHs.

As another non-limiting example, if the control information is the same kind of control information, and the multiple channels are all PSFCHs, then the arrangement order of each PSFCH can be determined according to the data transmission mode of the PSSCH associated with each PSFCH, wherein , the data transmission mode can be selected from unicast, multicast, and broadcast.

In a specific implementation, the UE may first determine the data transmission mode of the PSSCH associated with each PSFCH. Afterwards, the arrangement order of each PSFCH may be determined according to the data transmission manner.

For example, the data transmission mode only includes unicast and multicast. In this case, the UE may sort the PSFCH associated with the PSSCH using multicast transmission data first, and sort the PSFCH associated with the PSSCH using unicast transmission data at the back , that is, the transmission power of the PSFCH associated with the PSSCH of the multicast transmission data is preferentially allocated. Conversely, the UE may sort the PSFCH associated with the PSSCH using unicast transmission data first, and sort the PSFCH associated with the PSSCH using multicast transmission data at the back, that is, preferentially allocate the transmit power of the PSFCH associated with the PSSCH using unicast transmission data. .

In a specific implementation, when the data transmission modes of the PSSCHs associated with each PSFCH are the same, the UE may randomly generate the arrangement order of each PSFCH, and determine the arrangement order of each PSFCH. As a variant example, the UE may also determine the arrangement order of each PSFCH according to the resource index value of the resource occupied by each PSFCH. Among them, the resources occupied by the PSFCH may be ranked first with the smaller resource index values, that is, the transmission power of the PSFCH with the smaller resource index value may be preferentially allocated; or, the resources occupied by the PSFCH may be ranked with the larger resource index values. That is, the transmission power of the PSFCH with the smaller resource index value is preferentially allocated.

As another variation example, the UE may also determine the arrangement order of the respective PSFCHs according to the first symbol (symbol) or the first time slot (slot) of the resources occupied by the respective PSFCHs. In a specific implementation, the first symbol of the resource occupied by the PSFCH or the PSFCH with the first time slot before the first time slot (that is, the first time slot) can be sorted first, that is, the first symbol or the first time slot is preferentially allocated in the The transmit power of the previous PSFCH.

In a specific implementation, if the first symbols or first time slots of multiple PSFCHs are the same, the time domain lengths of these PSFCHs can be compared, and the PSFCHs with longer time domain lengths are sorted first, that is, the time domain lengths with longer time domain lengths are preferentially allocated. The transmit power of the long PSFCH. Alternatively, if there are multiple PSFCHs with the same first symbol or first time slot, the time domain lengths of these PSFCHs can be compared, and the PSFCHs with shorter time domain lengths are sorted first, that is, the PSFCHs with shorter time domain lengths are preferentially allocated transmit power.

In a specific implementation, if there are multiple PSFCHs with the same first symbol or first time slot, and the time domain lengths of these PSFCHs are the same, the UE can randomly select the order of the PFSCH, and sequentially allocate the transmission of the PSFCH according to the random order. power.

As another variation example, the UE may also determine the arrangement order of each PSFCH according to the first symbol (symbol) or the first time slot (slot) of the time-frequency resource occupied by the PSSCH associated with each PSFCH. The first symbol of the resource occupied by the PSSCH associated with the PSFCH or the PSFCH with the first time slot can be sorted first, that is, the transmission of the first symbol of the associated PSSCH or the PSFCH with the first time slot is preferentially allocated. power. As another non-limiting example, if the control information is different control information and the multiple channels are all PSFCHs, the UE may first determine the arrangement order of various control information, and then the UE may The arrangement order of the information determines the arrangement order of each physical direct link feedback channel.

In a specific implementation, if the first symbols or first time slots of the time-frequency resources occupied by PSSCHs associated with multiple PSFCHs are the same, the time domain lengths of these PSSCHs can be compared, and the PSSCHs with longer time domain lengths are ranked first. , that is, the transmission power of the first symbol of the associated PSSCH or the first PSFCH with a longer time domain length is preferentially allocated. Alternatively, if there are multiple PSSCHs with the same first symbol or the same first time slot, the time domain lengths of these PSSCHs can be compared, and the PSSCH with the shorter time domain length is ranked first, that is, the first symbol associated with the PSSCH is preferentially allocated Or the transmit power of the first PSFCH with a shorter time domain length.

In a specific implementation, if the first symbol or first time slot of the time-frequency resources occupied by the PSSCHs associated with multiple PSFCHs is the same, and the time domain lengths of these PSSCHs are the same, the UE may randomly select the ordering of the PFSCHs and follow the This random ordering sequentially allocates the transmit power of the PSFCH.

In a specific implementation, the priorities of various different control information can be predefined. As a non-limiting example, the control information includes SR information, HARQ feedback information and CSI. The priorities of the SR information, the HARQ feedback information, and the CSI may be pre-defined in sequence to decrease. Alternatively, priorities of the HARQ feedback information, the SR information, and the CSI may be pre-defined to decrease sequentially. Alternatively, the HARQ feedback information, the priority of the CSI, and the SR information may be pre-defined to decrease sequentially. Alternatively, the priorities of the SR information, the HARQ feedback information, and the CSI may be pre-defined to decrease in sequence. Alternatively, the priorities of the CSI, the HARQ feedback information, and the SR information may be pre-defined in sequence to decrease. Alternatively, the priorities of the CSI, the SR information, and the HARQ feedback information may be pre-defined to decrease in sequence. Afterwards, the arrangement order of various control information may be determined according to the pre-defined priorities of various control information.

As a further specific embodiment, the multiple channels are different types of channels. In this case, the UE may first determine the arrangement order of the different types of channels, and then determine each physical direct connection according to the arrangement order of the various types of channels. The order in which the link feedback channels are arranged. The different types of channels may include at least the following two items: PSFCH, PSSCH, PSCCH, and PSDCH.

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

Take the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports the transmission of HARQ feedback information, and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (for example, in the same time slot), the order of each PSFCH can be determined according to the priority of the PSSCH corresponding to the PSFCH, The transmit power of the PSFCH with higher priority is allocated preferentially.

In the specific implementation, it is assumed that there are M PSFCHs, where M is a positive integer greater than 1, wherein PSFCH1 is N1, associated PSSCH1, PSFCH2 is N2, associated PSSCH2,..., PSFCHn is Nn, associated PSSCHn, N1, N2 ..., Nn, and n are positive integers. N1+N2+...+Nn=M. In addition, the priorities of PSSCH1, PSSCH2, ..., PSSCHn are sequentially decreased. At this time, the UE may preferentially allocate the transmit power of the N1 PSFCH1s, and then sequentially allocate the transmit power of the PSFCH2, . . . , and PSFCHn. For each PSFCH1 or PSFCH2 or other PSFCHs, power allocation may be performed according to the following similar technical solutions, which will not be described here.

In a specific implementation, it is assumed that there are two PSFCHs, wherein PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 has a higher priority than PSSCH2. At this time, the UE can preferentially allocate the transmit power of PSFCH1. Assuming that P _PSFCH1 represents the transmit power of PSSCH1, the transmit power of this channel PSSCH1 may be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, P _CMAX indicates the maximum transmit power of the user equipment, and P _typical indicates the number of frequency domain resources at least related to PSFCH1 associated transmit power. Specifically, _PCMAX can represent the maximum transmit power of the user equipment on a component carrier. The parameters related to the transmit power value of P _typical may include at least the number of frequency domain resources of PSFCH1 (eg, the number of resource blocks and/or the number of sub-channels, etc.), and/or the path loss of the direct link of the UE, and the like.

Continue to take the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports the transmission of HARQ feedback information, and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (for example, in the same time slot), the arrangement order of each PSFCH can be determined according to the communication distance of each PSFCH transmission data, The transmit power of the PSFCH with higher priority is allocated preferentially. It should be noted that the communication distance may refer to the actual communication distance, or may refer to the communication distance represented by RSSI or RSRP, and the specific content may refer to the foregoing, which will not be repeated here.

In a specific implementation, it is assumed that there are two PSFCHs, wherein the communication distance corresponding to PSFCH1 is greater than the communication distance corresponding to PSFCH2, and the transmit power is allocated in descending order of the communication distance. At this time, the transmit power of PSFCH1 can be preferentially allocated. Assuming that P _PSFCH1 represents the transmit power of PSFCH1, the transmit power of this channel PSFCH1 can be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit The maximum transmit power on the carrier, P _typical represents at least the transmit power related to the number of frequency domain resources of PSFCH1.

In a specific implementation, it is assumed that there are two PSFCHs, wherein the communication distance corresponding to PSFCH1 is greater than the communication distance corresponding to PSFCH2, and the transmit power is allocated in descending order of the communication distance. At this time, the transmit power of PSFCH1 can be preferentially allocated. Assuming that P _PSFCH1 represents the transmit power of PSFCH1, the transmit power of this channel PSFCH1 can be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit The maximum transmit power on the carrier, P _typical represents at least the transmit power related to the number of frequency domain resources of PSFCH1.

In a specific implementation, if there are multiple PSFCHs that need to be sent at the same time, the UE can preferentially allocate the transmit power of the PSFCH that is ranked first according to the data transmission mode corresponding to the PSSCH associated with the PSFCH.

For example, it is assumed that there are two PSFCHs, wherein PSFCH1 is associated with PSSCH1 and PSFCH2 is associated with PSSCH2, and PSSCH1 adopts multicast transmission and PSSCH2 adopts unicast transmission. When the pre-defined priority of multicast is higher than that of unicast, the UE can preferentially allocate the transmit power of PSFCH1. Assuming that P _PSFCH1 represents the transmit power of PSFCH1, the transmit power of this channel PSFCH1 can be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit Maximum transmit power on the carrier. P _typical represents the transmit power related to at least the number of frequency domain resources of PSFCH1. The parameters related to the transmit power value of P _typical may include at least the number of frequency domain resources of PSFCH1 (eg, the number of resource blocks and/or the number of sub-channels, etc.), and/or the path loss of the direct link of the UE.

For example, it is assumed that there are two PSFCHs, wherein PSFCH1 is associated with PSSCH1 and PSFCH2 is associated with PSSCH2, and PSSCH1 adopts unicast transmission and PSSCH2 adopts multicast transmission. When the predefined multicast priority is lower than the unicast priority, the UE can preferentially allocate the transmit power of PSFCH1. Assuming that P _PSFCH1 represents the transmit power of PSFCH1, the transmit power of this channel PSFCH1 can be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit Maximum transmit power on the carrier. P _typical represents at least the transmit power related to the number of PSFCH1 frequency domain resources. The parameters related to the transmit power value of P _typical may include at least the number of frequency domain resources of PSFCH1 (eg, the number of resource blocks and/or the number of sub-channels, etc.), and/or the path loss of the direct link of the UE.

In a specific implementation, when the control information is different control information and the multiple channels are all PSFCHs, after the UE determines the arrangement order of the respective PSFCHs, transmit power may be allocated to the respective PSFCHs in sequence.

As a non-limiting example, if multiple PSFCHs need to be sent simultaneously, and the priority of the PSFCH carrying CSI is lower than that of the PSFCH carrying HARQ feedback information, the UE may preferentially allocate power to the PSFCH carrying HARQ feedback information. Those skilled in the art understand that if there are multiple PSFCHs carrying CSI or multiple PSFCHs carrying HARQ feedback information, the foregoing embodiment can be used, and details are not repeated here.

For example, suppose there are two PSFCHs, in which PSFCH1 is associated with PSSCH1 and PSFCH2 is associated with PSSCH 2, and PSSCH1 carries HARQ feedback information, PSSCH2 carries CSI, and the priority of HARQ feedback information is higher than that of CSI. At this time, the transmission of PSFCH1 can be preferentially allocated power. Assuming that P _PSFCH1 represents the transmission power of PSSCH1, the transmission power of this channel PSSCH1 can be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit Maximum transmit power on the carrier. P _typical represents at least the transmit power related to the number of frequency domain resources of PSFCH1. The parameters related to the transmit power value of P _typical may include the number of frequency domain resources of PSFCH1 (eg, the number of resource blocks and/or the number of sub-channels, etc.), and/or the path loss of the direct link of the UE, and the like.

For another example, suppose there are two PSFCHs, wherein PSFCH1 is associated with PSSCH1, and PSFCH2 is associated with PSSCH 2, and PSSCH1 carries CSI, and PSSCH2 carries HARQ feedback information. The priority of the HARQ feedback information is lower than the priority of CSI, and can be allocated preferentially at this time. The transmit power of PSFCH1. Assuming that P _PSFCH1 represents the transmit power of PSSCH1, the transmit power of this channel PSSCH1 may be determined according to an existing protocol, which will not be described in detail here. Afterwards, the UE may allocate transmit power for PSFCH2. The transmit power of PSFCH2, P _PSFCH2 , may be min{P _CMAX -P _PSFCH1 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX - P _PSFCH1 and P _typical is selected, and P _CMAX indicates the maximum transmit power of the user equipment. Specifically, P _CMAX may indicate that the user equipment is in the unit The maximum transmit power on the carrier, P _typical represents at least the transmit power related to the number of frequency domain resources of PSFCH1.

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 decrease in sequence. Suppose there are 3 PSFCHs, namely PSFCH1, PSFCH2 and PSFCH3. The PSFCH1 carries the SR information, the PSFCH2 carries the CSI, and the PSFCH3 carries the HARQ feedback information. At this time, the UE may first determine the arrangement order of each PSFCH according to the SR information, the HARQ feedback information and the priority of the CSI, so as to preferentially allocate the transmit power of PSFCH1, then allocate the transmit power of PSFCH2, and finally allocate PSFCH3 transmit power.

In a specific implementation, for PSFCH2 transmitting the HARQ feedback information, its transmit power is min{P _CMAX -P _PSFCH1 , P _typical }, and for PSFCH3 transmitting the CSI, its transmit power is min{P _CMAX -P _PSFCH1 -P _PSFCH2 , P _typical }. Among them, min{P _CMAX -P _PSFCH1 , P _typical } indicates that the minimum value among P _CMAX -P _PSFCH1 and P _typical is selected, and min{P _CMAX -P _PSFCH1 -P _PSFCH2 , P _typical } indicates that P _CMAX -P _PSFCH1 - The minimum value among P _PSFCH2 and P _typical , P _CMAX indicates the maximum transmit power of the user equipment, specifically, P _CMAX may indicate the maximum transmit power of the user equipment on the element carrier, and P _PSFCH1 indicates the PSFCH1 that transmits the scheduling request information , P _PSFCH2 indicates the transmission power of the PSFCH2 that transmits the HARQ feedback information, and P _typical indicates the transmission power at least related to the number of frequency domain resources of the PSFCH1.

In a specific implementation, there may be multiple channels for transmitting the same control information, for example, there are M1 PSFCHs to transmit HARQ feedback information, M2 PSFCHs to transmit SR information, M3 PSFCHs to transmit CSI information, and M1, M2, and M3 are more than 2 At this time, if the priorities of SR, HARQ feedback information, and CSI information decrease in turn, then the transmission power allocation order of each PSFCH is: the transmission power of M2 PSFCHs that transmit SR is allocated first, and then the transmission power of HARQ feedback information is allocated and transmitted. The transmission power of M1 PSFCHs is finally allocated, and the transmission power of M3 PSFCHs for transmitting CSI information is finally allocated. For each PSFCH in which the same kind of control information is transmitted, power allocation can still be performed according to the embodiments of the related invention provided herein, which will not be repeated here.
