[0002] The present invention claims priority to a Chinese patent application filed with the Patent Office of China on September 27, 2023, with application number 202311272748.2 and invention name “Power Determination Method, User Equipment and Storage Medium”. The entire contents of the application are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of data communication technology, and in particular to a power determination method, user equipment, and computer-readable storage medium. Background Art

[0004] Currently, there are two air interface technologies for sidelink (SL) communications: 4G Long Term Evolution (LTE) and 5G New Radio (NR). In the future, SL communications may utilize the sixth-generation mobile communication technology (6G). SL can operate in unlicensed frequency bands, known as Sidelink Unlicensed (SL-U). Unlicensed frequency bands are measured in approximately 20 MHz of listen before talk (LBT) bandwidth. The transmission frequency domain of a physical sidelink feedback channel (PSFCH) in an SL-U falls within one LBT bandwidth. When the frequency domain needs to meet the occupied channel bandwidth (OCB) requirements, SL-U defines two formats for PSFCH; one of them is that PSFCH transmission adopts dedicated interleaving, and the device occupies all physical resource blocks (PRBs) on one interleaving in the resource block set (RB set) at a time when transmitting PSFCH feedback; however, the interleaving in the RB set may be 10 PRBs or 11 PRBs. When performing power control, it may be necessary to ensure that the power of each PSFCH transmission is equal. Therefore, in the area with OCB requirements in the unlicensed frequency band, considering the OCB requirements and the power spectral density (PSD) constraints, how to determine the PSFCH transmission power is an unresolved problem.

[0027] To facilitate understanding of the solutions of the embodiments of the present application and to provide a clear and concise description of the following embodiments, a brief introduction to the relevant technologies is first given.

[0028] As shown in Figure 1, in a SideLink (SL) communication system, when user equipment (UE) needs to transmit services, the service data between the UEs does not pass through the network side, that is, it is not forwarded through the cellular link between the UE and the base station. Instead, it is directly transmitted from the source UE to the target UE via the SL. This approach can reduce the burden on the cellular network, reduce the battery power consumption of user equipment, and improve the robustness of the network infrastructure, effectively meeting the requirements of high-data-rate services and proximity services. It also supports direct communication in scenarios without network coverage, which can meet special communication needs such as public safety. In this case, the devices operate on resources defined by the communication resource pool.

[0029] As shown in Figure 2, multiple nominal channel bandwidths are defined in the unlicensed spectrum, each with a bandwidth of 20 MHz. When operating in the unlicensed spectrum, a device must listen on the defined nominal channel bandwidth and transmit only when the channel is idle. The nominal channel bandwidth can be divided based on the frequency domain. For example, a segment of unlicensed spectrum can be divided into 20 MHz bands, resulting in multiple nominal channel bandwidths.

[0030] Generally speaking, when the device is working, it uses at least 1 20M bandwidth. Some areas have occupied bandwidth (OCB) requirements for the nominal channel bandwidth defined on the unlicensed basis, that is, the device needs to occupy at least 80% of the frequency domain resources on the nominal channel bandwidth. Since OCB is a regional requirement, SL-U designed the frequency domain structure for both with and without OCB requirements during the analysis process; the subsequent embodiments of this application mainly focus on explaining the channel structure with OCB requirements and the corresponding method for calculating the transmission power of the physical sidelink feedback channel (PSFCH).

[0031] The SL-U channel structure definition proposes a resource block set (RB set) channel structure. This resource block set is similar to the nominal bandwidth defined in the unlicensed mode, approximately 20M. Similarly, the OCB requirement must also be met within the RB set. Two frequency domain formats are defined for the PSFCH feedback channel within the RB set, as shown in Figures 3 and 4. Figure 3 shows the format of a shared interleaved resource block (RB) and one dedicated physical resource block (PRB); Figure 4 shows the format of a dedicated interleaved RB for PSFCH. Furthermore, in the format shown in Figure 3, when a device transmits a PSFCH within the current RB set, it must transmit signals on both shared interleaved RBs and dedicated PRBs. Transmitting signals on shared interleaved PRBs primarily meets the OCB requirement, while transmitting signals on dedicated PRBs carries the useful information required by the PSFCH. The shared interleaved PRBs are located in the same RB set for all devices, while the dedicated PRBs may be located in different locations. In the format shown in FIG4 , in the current RB set, when a device transmits a PSFCH, useful information is directly carried on a dedicated interleaved RB in the RB set, and the resource locations of the dedicated interleaved RBs for different UEs may be different.

[0032] It should be noted that the interleaving on the RB set is 11 or 10 PRBs with equal intervals in the RB set; under a 15kHz subcarrier spacing (SCS), there are 10 interleavings on an RB set; under a 30kHz SCS, there are 5 interleavings on each RB set. In the time domain, PSFCH appears on the SL communication resource pool according to a certain period. A PSFCH time domain opportunity is often associated with multiple past SL data transmissions. Therefore, the device may need to transmit multiple PSFCH resources simultaneously in the PSFCH time slot. These PSFCH resources may be located in the same RB set or different RB sets. Since multiple PSFCHs in the frequency domain may be discrete in the frequency domain and the UE's transmit power is limited, when the device transmits PSFCH, if the number of scheduled PSFCH transmissions or the device's transmit power does not meet the requirements, it is necessary to adjust the number and power of PSFCH transmissions according to the priority of PSFCH transmission, so that the device can successfully transmit multiple PSFCH resources. The embodiment of the present application mainly explains the method for determining power and resources using a dedicated interleaving format for PSFCH.

[0033] Please refer to Figure 5. In the SL resource pool, PSFCH resources in the time domain appear periodically. In the frequency domain, for each RB set, the interleaving of the PSFCH time domain symbols in that RB set can be mapped to a subband (subchannel) in a time slot of the same RB set in the past according to certain mapping rules. In Figure 5, the PSFCH period is the time slot in two resource pools. Assuming that an RB set contains two subchannels, each subchannel in each time slot can be uniquely mapped to a set of feedback resources according to certain rules. This set of feedback resources includes m. A PSFCH feedback resource can be considered as an interleaving in the RB set. This means that some PSFCHs contain 10 PRBs and some contain 11 PRBs.

[0034] It should be noted that the signaling or parameters of the SL-U in the embodiment of the present application can be obtained through configuration, or pre-configured, or scheduled to be obtained, which are collectively referred to as configuration in the text without limiting the distinction; the configuration in the embodiment of the present application can include the network configuring the device, the device configuring another device, or pre-configuration. It is worth noting that, regardless of whether the PSFCH transmission includes 10 PRBs or the PSFCH transmission includes 11 PRBs, the transmission power between the PRBs actually transmitted within a PSFCH transmission is equal.

[0035] For PSFCH transmission on SL, downlink power control may be enabled or not, which is determined by the configuration or pre-configured parameters. In either case, the PSFCH transmission transmitted by the UE on the PSFCH opportunity needs to meet the following conditions: the number of PSFCH transmissions actually transmitted by the UE on a PSFCH feedback opportunity N Tx,PSFCH No more than the maximum number of PSFCH transmissions N of the UE max,PSFCH ; The actual transmission power of the UE at the PSFCH feedback opportunity does not exceed the configured UE maximum transmission power; When the UE transmits PSFCH on a dedicated PRB on an RB set, it may also need to transmit signals on a configured or pre-configured shared interleaved RB in order to meet OCB requirements.

[0036] In order to solve the problem of how to determine the PSFCH transmission power in an area with OCB requirements in an unlicensed frequency band, taking into account the OCB requirements and the power spectrum density (PSD) restrictions, the embodiment of the present application provides a power determination method, a user device and a computer-readable storage medium. In the embodiment of the present application, in the process of determining the transmission power of the PSFCH, the number of PSFCH transmissions to be transmitted at the PSFCH transmission opportunity is first determined; then, the transmission power of each PSFCH to be transmitted can be determined based on the number of PSFCHs to be transmitted. Through the scheme of the embodiment of the present application, when the user equipment schedules multiple PSFCH feedback transmissions, the transmission power of each PSFCH transmission can be determined while meeting the maximum number of PSFCH transmissions of the user equipment, the maximum transmission power of the equipment and the channel occupancy requirements.

[0037] The power determination method of the embodiments of the present application may be executed by a terminal device. The terminal device may also be a smartphone, desktop computer, tablet computer, laptop computer, smart TV, smart voice interaction device, smart home appliance, or other terminal device such as smart transportation equipment, smart home equipment, robot, or drone.

[0038] The execution subject of the power determination method of the embodiment of the present application can be a server. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. This embodiment of the present application is not limited to this.

[0039] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, and the like. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, and the like that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments in which tasks are performed by remote processing devices connected via a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media, including storage devices.

[0040] It should be noted that in each specific embodiment of the present application, when it comes to the need to perform relevant processing based on the attribute information or attribute information set of an object (such as a user, etc.) and other data related to the characteristics of the object, the permission or consent of the corresponding object will be obtained first, and the collection, use and processing of such data will comply with relevant laws, regulations and standards.

[0041] The power determination method, user equipment, and computer-readable storage medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the power determination method in the embodiments of the present application is described.

[0042] Please refer to Figure 6, which is a schematic diagram of the steps of a power determination method provided in an embodiment of the present application. As shown in Figure 6, the power determination method includes the following steps S110-S120, and each step is introduced in sequence below:

[0043] Step S110: determining the number of PSFCH transmissions to be transmitted at a PSFCH transmission opportunity.

[0044] In an embodiment of the present application, in the process of power determination, it is first necessary to determine the number of PSFCH transmissions to be transmitted at the PSFCH transmission opportunity; the PSFCH transmission opportunity referred to in the embodiment of the present application is the opportunity when one user terminal is about to send a PSFCH to be transmitted to another user terminal, wherein the number of PSFCH transmissions to be transmitted can be multiple, and the power determination process in the embodiment of the present application is based on the PSFCH transmission in the form of dedicated interleaving, and when the device transmits PSFCH feedback, it occupies all dedicated resource blocks on one interleaving in the resource group at one time.

[0045] In an embodiment of the present application, the number of dedicated resource blocks carried by each PSFCH in a resource group is not fixed. For example, there may be 10 or 11 dedicated resource blocks in a resource group; and each dedicated resource block corresponds to a corresponding user device, that is, the user device will only transmit data on the dedicated resource block corresponding to it.

[0046] It is understood that the PSFCH to be transmitted is the PSFCH that the UE is about to transmit, that is, one of the UEs needs to send information to the target UE, and the relevant content information is carried on the PSFCH. And when one of the UEs transmits the PSFCH to the target UE, multiple PSFCHs can be transmitted at one time.

[0047] Step S120: Determine the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted.

[0048] In an embodiment of the present application, for the PSFCHs that are to be transmitted, it is necessary to determine the number of PSFCHs to be transmitted, and then the transmit power of the PSFCH can be calculated based on the number of PSFCHs to be transmitted. Among them, when determining the PSFCH transmit power, it is mainly based on the number of PSFCHs to be transmitted; the difference in the number of PSFCHs to be transmitted will cause the actual transmit power of the PSFCHs to be transmitted to be different. The actual transmit power of the PSFCH to be transmitted not only needs to meet the OCB requirements, but also cannot be greater than the maximum transmit power that the UE can generate, and the number of PSFCHs actually transmitted by each UE at a PSFCH feedback opportunity cannot exceed the maximum PSFCH transmission number of the UE.

[0049] Please refer to Figure 7, which is a schematic diagram of the sub-steps of step S110 in Figure 6. Figure 7 is a schematic diagram of the steps of determining each PSFCH to be transmitted provided by an embodiment of the present application. Specifically, the following steps S111 to S113 may be included:

[0050] Step S111: Acquire the PSFCH scheduled by the user equipment.

[0051] Step S112: When the number of PSFCHs scheduled by the user equipment is less than or equal to the maximum number of PSFCHs to be transmitted by the user equipment, all PSFCHs scheduled by the user equipment are used as PSFCHs to be transmitted.

[0052] Step S113, when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs transmitted by the user equipment, select the PSFCH to be transmitted from the PSFCHs scheduled for the user equipment according to at least one of the PSFCH transmission priority and the PSFCH transmission information content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs transmitted by the user equipment.

[0053] In an embodiment of the present application, in the process of determining each PSFCH to be transmitted, the PSFCH that needs to be scheduled of the user equipment that is ready to perform PSFCH transmission is first obtained; then the number of scheduled PSFCHs is determined; when the number of PSFCHs scheduled for the user equipment is less than or equal to the maximum number of PSFCHs for transmission of the user equipment, all PSFCHs scheduled for the user equipment will be used as PSFCHs to be transmitted; when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs for transmission of the user equipment, the PSFCH to be transmitted is selected from the PSFCHs scheduled for the user equipment based on at least one of the PSFCH transmission priority and the PSFCH transmission information content, wherein the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs for transmission of the user equipment, so as to achieve the maximum possible data transmission and improve the efficiency of data transmission.

[0054] In one possible exemplary embodiment, if the number of PSFCHs scheduled for a user equipment is four and the maximum number of PSFCHs that the user equipment can transmit is five, all four PSFCHs scheduled for the user equipment are used as PSFCHs to be transmitted. The maximum number of PSFCHs that can be transmitted can be pre-set based on the performance of the user equipment; the maximum number of PSFCHs that can be transmitted can vary for different user equipment.

[0055] In a possible exemplary embodiment, the number of PSFCHs scheduled for the user equipment is 7, and the maximum number of PSFCHs transmitted by the user equipment is 5. At this time, the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs transmitted by the user equipment, and it is necessary to select and process the 7 scheduled PSFCHs. The selection can be performed based on the priority of each PSFCH, and the 2 PSFCHs with the lowest priority can be discarded, and the other 5 PSFCHs with relatively higher priorities can be used as PSFCHs to be transmitted; or, in the process of selecting the 7 scheduled PSFCHs, the selection can also be performed based on the information content transmitted by each PSFCH. For example, two PSFCHs transmit indicative information of low importance, while the other five PSFCHs transmit substantive conversation information of high importance. Therefore, the two PSFCHs transmitting indicative information of low importance can be discarded, while the five PSFCHs transmitting substantive conversation information of relatively high importance can be used as PSFCHs to be transmitted. In this case, when the number of PSFCHs scheduled for the user equipment is greater than the maximum number of PSFCHs to be transmitted by the user equipment, the number of PSFCHs to be transmitted is equal to the maximum number of PSFCHs to be transmitted by the user equipment, which can greatly improve the data transmission efficiency between user equipment.

[0056] In an embodiment of the present application, in the process of selecting the scheduled PSFCH, it can be determined based on only one of the PSFCH transmission priority and the PSFCH transmission information content, or a comprehensive judgment can be made based on the two. For example, the priority and the importance of the content can be uniformly weighted. For example, the highest transmission priority can be assigned a weight of 5, the secondary transmission priority can be assigned a weight of 3, and the lowest transmission priority can be assigned a weight of 1; the most important content can be assigned a weight of 4, the secondary content can be assigned a weight of 2, and the less important content can be assigned a weight of 1; therefore, in the subsequent process of PSFCH selection, the PSFCH can be weighted. For example, for a PSFCH with the highest transmission priority and the most important transmission content, a weight of 9 will be assigned; for a PSFCH with a secondary transmission priority and the less important transmission content, a weight of 4 will be assigned; the scheduled PSFCHs are weighted separately, and finally the PSFCH is selected based on the size of the weight, thereby improving the pertinence and reliability of data transmission.

[0057] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted may include the following steps S121:

[0058] Step S121: According to the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipment CMAX , determine the transmit power of each PSFCH to be transmitted, and the transmit power of each PSFCH to be transmitted is equal.

[0059] In the embodiment of the present application, since the transmit power of each PSFCH to be transmitted is equal, the actual transmit power of each PSFCH to be transmitted can be determined based on the number of PSFCHs to be transmitted and the maximum transmit power of the user equipment. The maximum transmit power of the user equipment can be determined based on the device performance of the user equipment, and the maximum transmit power of different user equipment may also vary.

[0060] In some embodiments of the present application, the PSFCH to be transmitted includes a first type PSFCH and / or a second type PSFCH, wherein the number of PRBs included in the first type PSFCH is K1, and the number of PRBs included in the second type PSFCH is K2, K1 is less than K2, and K1 and K2 are both positive integers; determining the PRB transmit power may include but is not limited to steps S131-step S132:

[0061] Step S131: For the first type of PSFCH, the transmit power of the PSFCH to be transmitted is used for K1 PRBs included in the first type of PSFCH, and the transmit power of each PRB is determined according to the value of K1.

[0062] Step S132, for the second type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K2, or, the transmission power of the PSFCH to be transmitted is used for K1 PRBs selected from the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K1.

[0063] In an embodiment of the present application, the PSFCH to be transmitted may include a first type of PSFCH and / or a second type of PSFCH, wherein the number of PRBs included in the first type of PSFCH is K1, and the number of PRBs included in the second type of PSFCH is K2, K1 is less than K2, and illustratively, K1 can be 10, and K2 can be 11; and for the first type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K1 PRBs included in the first type of PSFCH and the transmission power of each PRB is determined according to the value of K1; and for the second type of PSFCH, the transmission power of the PSFCH to be transmitted is used for the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K2, or, the transmission power of the PSFCH to be transmitted is used for K1 PRBs selected from the K2 PRBs included in the second type of PSFCH and the transmission power of each PRB is determined according to the value of K1.

[0064] In a possible exemplary embodiment, the first type of PSFCH includes 10 PRBs, and the second type of PSFCH includes 11 PRBs; for the first type of PSFCH, the transmission power of the first type of PSFCH is used for the 10 PRBs included and the transmission power of each PRB is determined by the value 10; for the second type of PSFCH, the transmission power of the second type of PSFCH is used for the 11 PRBs included and the transmission power of each PRB is determined by the value 11, or 10 PRBs are selected from the 11 PRBs, and the transmission power of each PRB is determined by the value 10.

[0065] In some embodiments of the present application, determining the transmit power of each PSFCH to be transmitted according to the number of PSFCHs to be transmitted may include the following steps S122-S123:

[0066] Step S122: determining the total number N of PRBs included in all PSFCHs to be transmitted and determining the transmit power of each PRB according to the total number N of PRBs.

[0067] Step S123: For each PSFCH to be transmitted, the transmission power of the PSFCH to be transmitted is determined based on the transmission power on each PRB and the number of PRBs contained in the PSFCH to be transmitted. The transmission power of the PSFCH to be transmitted is the sum of the transmission powers of all PRBs included in the PSFCH to be transmitted, wherein the number of PRBs contained in each PSFCH to be transmitted is K1 or K2, K1 is less than K2, and K1 and K2 are both positive integers.

[0068] In an embodiment of the present application, in the process of determining the transmission power of each PSFCH to be transmitted, the total number N of PRBs contained in all PSFCHs to be transmitted can also be determined, and the transmission power on each PRB can be determined based on the total number N of PRBs; wherein, the transmission power of the PSFCH to be transmitted is the sum of the transmission powers of all PRBs included in the PSFCH to be transmitted, wherein the number of PRBs contained in each PSFCH to be transmitted is K1 or K2, K1 is less than K2, and K1 and K2 are both positive integers.

[0069] In a possible exemplary embodiment, there are a total of 3 PSFCHs to be transmitted, including 1 first-class PSFCH and 2 second-class PSFCHs. At this time, the 3 PSFCHs contain a total of 32 PRBs; the transmission power of the first-class PSFCH can be determined based on the total number 32 and the number of PRBs it contains, which is 10; the transmission power of the second-class PSFCH can be determined based on the total number 32 and the number of PRBs it contains, which is 11.

[0070] In a possible exemplary embodiment, when power control is not enabled, the user equipment is scheduled for a total of N sch,Tx,PsFCH PSFCH transmission, according to the UE's maximum PSFCH transmission number capability, PSFCH transmission priority, PSFCH transmission information content to determine N Tx,PSFCH PSFCH transmissions are further used to determine the transmit power of each PSFCH transmission. Since the power of PSFCH transmissions with different numbers of PRBs can be equal or unequal, the per RB power density between different PSFCH transmissions can also be equal or unequal. Different calculation methods can be used to calculate the power in different situations. The specific method can be as follows:

[0071] When the power of PSFCH transmissions with different PRB numbers is equal and the per RB power density between different PSFCH transmissions is not equal, in the process of determining each PSFCH to be transmitted, the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipment are used. CMAX The actual transmit power of each PSFCH can be determined, and the calculation formula can be as follows: PSFCH,k (i) = PCMAX -10log 10 (N Tx,PSFCH )[dBm]

[0072] Among them, P CMAX is the maximum transmit power of the user equipment, N Tx,PSFCH is the number of PSFCHs to be transmitted, P PSFCH,k (i) The actual transmit power for each PSFCH;

[0073] In the process of determining the transmit power of each dedicated resource block, the actual transmit power of the PSFCH to be transmitted and the number of resource blocks can be directly calculated as follows:

[0074] When the PSFCH contains 10 PRBs, the transmit power of each PRB on the PSFCH is P PSFCH,k (i)-10log 10 (10)[dBm].

[0075] When the PSFCH contains 11 PRBs, the transmit power of each PRB on the PSFCH is P PSFCH,k (i)-10log 10 (11)[dBm].

[0076] When the power of PSFCH transmissions with different PRB numbers is equal and the per RB power density between different PSFCH transmissions is also equal, in the process of determining each PSFCH to be transmitted, the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipment are used. CMAX The actual transmit power of each PSFCH can be determined, and the calculation formula can be as follows: PSFCH,k (i) = P CMAX -10log 10 (N Tx,PSFCH )[dBm]

[0077] Among them, P CMAX is the maximum transmit power of the user equipment, N Tx,PSFCH is the number of PSFCHs to be transmitted, P PSFCH,k (i) is the actual transmit power of each PSFCH.

[0078] In the process of determining the transmit power of each dedicated resource block, the actual transmit power of the PSFCH to be transmitted and the number of resource blocks can be directly calculated as follows:

[0079] When the PSFCH contains 10 PRBs, the transmit power of each PRB on the PSFCH is P PSFCH,k (i)-10log10 (10)[dBm].

[0080] When the PSFCH contains 11 PRBs, the user equipment only transmits 10 of them. At this time, the transmit power of each PRB on the PSFCH is P PSFCH,k (i)-10log 10 (10)[dBm].

[0081] When the power of PSFCH transmissions with different PRB numbers is not equal and the PRB power density between different PSFCH transmissions is equal, the number of PSFCH transmissions N is used. Tx,PSFCH , determine the total number of PRBs N contained in all transmitted PSFCHs, the number of PRBs contained in each PSFCH is N_PSFCH, then the transmit power of each PSFCH transmission is P CMAX -10log 10 (N)+10log 10 (N_PSFCH) [dBm], where N_PSFCH may be 10 or 11, which is related to the number of PRBs contained in the corresponding PSFCH. For example, the transmit power of a PSFCH transmission containing 10 PRBs is P CMAX -10log 10 (N)+10log 10 (10) [dBm]; The transmit power of the PSFCH transmission containing 11 PRBs is P CMAX -10log 10 (N)+10log 10 (11)[dBm].

[0086] In the embodiment of the present application, in the process of determining the actual transmit power of each PSFCH to be transmitted based on the number of PSFCHs to be transmitted, a first transmit power is first determined based on the number of configured PRBs, where the number of configured PRBs corresponds to 10 or 11. Then, a power determination parameter is determined based on the first transmit power and the number of PSFCHs to be transmitted. If the power determination parameter satisfies a preset power limit condition, the first transmit power is used as the actual transmit power of the PSFCH to be transmitted.

[0090] Step S128: According to the number of PSFCHs to be transmitted and the maximum transmit power P of the user equipment, CMAX Determine the second transmission power P" PSFCH,one .

[0091] Step S129: Set the second transmission power P" PSFCH,one and the first transmission power P′ PSFCH,one The smaller value is used as the final transmit power of the PSFCH to be transmitted.

[0092] In an embodiment of the present application, when the power judgment parameter does not meet the preset power limit condition, at least one PSFCH in the PSFCH to be transmitted will be discarded according to at least one of the PSFCH transmission priority and the PSFCH transmission content until the preset power limit condition is met to obtain the final PSFCH to be transmitted; the second transmission power is determined based on the final number of PSFCHs to be transmitted and the maximum transmission power of the user equipment; finally, the first transmission power and the second transmission power are compared, and the smaller value between the two is used as the transmission power of the final PSFCH to be transmitted.

[0093] It can be understood that when the power judgment parameter does not meet the preset power limit conditions, a comprehensive judgment can be made based on the PSFCH transmission priority, the PSFCH transmission content, or a combination of the two, so that at least one PSFCH to be transmitted can be discarded until the preset power limit conditions are met and the final PSFCH to be transmitted is obtained.
