[0033] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0034] In related technologies, PSFCH transmission power is typically configured based on the power configuration of the PSFCH for downlink power control, with the same power configured for each PSFCH in a terminal device. However, this approach may cause the power of the PSFCH based on downlink power control to exceed the maximum power of the PSFCH specified in some resource pools, resulting in confusion in the power configuration of the terminal device.

[0035] In the present disclosure, the network device can determine the actual transmission power of the PSFCH based on the actually configured PSFCH transmission time-frequency resources and the resource pool corresponding to the PSFCH, so as to configure the actual transmission power for the PSFCH, thereby ensuring the rationality of the PSFCH transmission power configuration and solving the problem of power configuration confusion of the terminal device.

[0036] The following describes in detail a method and apparatus for configuring PSFCH transmission power provided by the present disclosure with reference to the accompanying drawings.

[0037] See Figure 2 , Figure 2 This is a flow chart of a method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 2 As shown, the method may include but is not limited to the following steps:

[0038] Step 201: Determine the actual transmission power of the PSFCH according to the actually configured PSFCH transmission time-frequency resources and the resource pool corresponding to the PSFCH.

[0039] In this disclosure, a network device can configure time-frequency resources for the PSFCH in a sidelink transmission of a terminal device. For example, at a PSFCH transmission moment, i.e., a sidelink frame containing a PSFCH, a total of N PSFCHs are transmitted simultaneously. These N PSFCHs have a total of R resource pools, and the sum of the number of PSFCHs in the R resource pools is N. The R resource pools here can be understood as the resource pools corresponding to the PSFCHs.

[0040] It should be noted that there may be one or more resource pools corresponding to the PSFCH, and this disclosure does not limit this.

[0041] In the present disclosure, the transmission time-frequency resources of the PSFCH are configured on the resource pool of the terminal device, and each resource pool may have a maximum power supported by the time-frequency resources configured in the resource pool on the PSFCH.

[0042] In the present disclosure, the actual transmission power of the PSFCH may be determined based on the number of resource pools corresponding to the PSFCH, the number of PSFCHs on each resource pool, the maximum power supported by each resource pool on the PSFCH, and the like.

[0043] The actual transmission power of the PSFCHs on different resource pools may be the same or different. The PSFCHs on the same resource pool may be configured with the same actual transmission power.

[0044] Step 202: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power of the PSFCH.

[0045] In the present disclosure, after the actual transmission power of the PSFCH is determined, configuration information may be sent to the terminal device to configure the actual transmission power for each PSFCH of the terminal device.

[0046] The configuration information may include the actual transmission power of the PSFCH on each resource pool, and the PSFCHs belonging to the same resource pool may be configured with the same actual transmission power.

[0047] In the embodiment of the present disclosure, the actual transmission power of the PSFCH is determined based on the actually configured PSFCH transmission time-frequency resources and the resource pool corresponding to the PSFCH, so as to configure the actual transmission power for the PSFCH. Compared with configuring the power control power to each PSFCH on the terminal device, the rationality of the PSFCH transmission power configuration can be guaranteed, thereby solving the problem of chaotic power configuration of the terminal device.

[0048] See Figure 3 , Figure 3 This is a flow chart of another method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 3 As shown, the method may include but is not limited to the following steps:

[0049] Step 301: Determine the power control power of the PSFCH on each resource pool.

[0050] Among them, each resource pool may refer to a resource pool corresponding to a PSFCH, and there may be one or more resource pools corresponding to a PSFCH.

[0051] In the present disclosure, the initial power, compensation coefficient, downlink path loss reported by the terminal device, etc. can be obtained, and the power control power of the PSFCH on each resource pool can be calculated based on the initial power, compensation coefficient, downlink path loss, etc. The calculation method of the power control power of the PSFCH on each resource pool can be referred to the following formula (1):

[0052] P PSFCH,one =P O,PSFCH +10log 10 (2 μ )+α PSFCH ·PL (1)

[0053] Among them, P PSFCH,one Indicates the configured power of a single PSFCH; P O,PSFCH With α PSFCH Indicates the initial power and compensation coefficient actually configured by the network device; PL indicates the downlink path loss reported by the terminal device; the value of μ is related to the bandwidth of the subcarrier. For example, if the subcarrier bandwidth is 15 kHz, the value of μ is 0; if the subcarrier bandwidth is 30 kHz, the value of μ is 1.

[0054] In the present disclosure, for the same terminal device, the power control power of the PSFCH on each resource pool can be the same, that is, the power control power of the PSFCH on each resource pool is the same.

[0055] Step 302: Determine the actual transmission power corresponding to the PSFCH of each resource pool according to the power control power, the first maximum power of the PSFCH on each resource pool, and the second maximum power supported by the terminal device on the PSFCH.

[0056] In the present disclosure, there may be one or more resource pools corresponding to PSFCH, and the time-frequency resources of PSFCH are configured on the resource pool of the terminal device. There may be one or more PSFCHs on each resource pool, and the network device may configure the first maximum power for the PSFCH on each resource pool of the terminal device through radio resource control (RRC) signaling, so that each resource pool has the maximum power supported by the time-frequency resources in its configured resource pool.

[0057] In the present disclosure, the first maximum power of the PSFCH on each resource pool may be the same or different, and the present disclosure does not limit this.

[0058] In the present disclosure, the terminal device can report the maximum power supported on the PSFCH, that is, the second maximum power, to the network device, so that the network device can obtain the second maximum power supported by the terminal device on the PSFCH.

[0059] In the present disclosure, the actual transmission power corresponding to the PSFCH of each resource pool can be understood as the actual transmission power corresponding to the PSFCH on each resource pool. The actual transmission power corresponding to the PSFCH on the same resource pool is the same, and the actual transmission power corresponding to the PSFCH on different resource pools may be different or the same. This disclosure does not limit this.

[0060] In the present disclosure, for each resource pool, the smaller power value between the power control power and the first maximum power corresponding to each resource pool can be determined, and based on the smaller power value corresponding to each resource pool, the total power corresponding to all resource pools can be determined. Based on the size of the total power and the second maximum power, the actual transmission power corresponding to the PSFCH of each resource pool can be determined.

[0061] Step 303: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool.

[0062] In the present disclosure, after determining the actual transmission power corresponding to the PSFCH of each resource pool, the network device can send configuration information to the terminal device to configure the actual transmission power corresponding to each resource pool for the PSFCH of each resource pool on the terminal device.

[0063] In the present disclosure, the actual transmission power configured for PSFCHs on the same resource pool can be the same. For example, if there are three PSFCHs on resource pool A and the actual transmission power corresponding to the PSFCH on resource pool A is determined to be a, the actual transmission power of all three PSFCHs on resource pool A can be configured to be a.

[0064] Optionally, the actual transmission power configured for a PSFCH on the same resource pool can be less than or equal to the actual transmission power corresponding to the PSFCH in the resource pool. For example, if there are two PSFCHs on a resource pool, and the actual transmission power corresponding to the PSFCHs in the resource pool is b, the actual transmission power of one PSFCH can be configured to b, and the actual transmission power of the other PSFCH can be configured to a value less than b.

[0065] In the embodiment of the present disclosure, by determining the power control power of the PSFCH on each resource pool, according to the power control power, the first maximum power of the PSFCH on each resource pool and the second maximum power supported by the terminal device on the PSFCH, the actual transmission power corresponding to the PSFCH of each resource pool is determined, and configuration information is sent to the terminal device to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool. Thus, by determining the actual transmission power corresponding to the PSFCH of each resource pool according to the power control power, the first maximum power corresponding to each resource pool and the second maximum power supported by the terminal device on the PSFCH, and configuring the actual transmission power corresponding to the PSFCH of each resource pool to the PSFCH on each resource pool, compared to configuring the power control power to each PSFCH on the terminal device, the rationality of the PSFCH transmission power configuration can be guaranteed, thereby solving the problem of chaotic power configuration of the terminal device.

[0066] See Figure 4 , Figure 4 This is a flow chart of another method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 3 As shown, the method may include but is not limited to the following steps:

[0067] Step 401: Determine the power control power of the PSFCH on each resource pool.

[0068] In the embodiment of the present disclosure, step 401 can be implemented in any of the ways in the embodiments of the present disclosure, which is not limited in the embodiment of the present disclosure and will not be described in detail.

[0069] Step 402: For each resource pool, determine a smaller power from the power control power and the first maximum power as a first candidate power corresponding to the PSFCH of each resource pool.

[0070] In the present disclosure, for each resource pool, the network device can compare the power control power and the first maximum power to determine the smaller power from the power control power and the first maximum power, and use the smaller power as the first candidate power corresponding to the PSFCH of each resource pool.

[0071] For example, at a PSFCH transmission moment, that is, a sidelink frame containing PSFCH has N PSFCHs transmitted simultaneously, wherein these N PSFCHs have a total of T resource pools. i There is a K i PSFCH transmission, satisfying Resource Pool R i The first candidate power corresponding to the upper PSFCH is determined as shown in the following formula (2):

[0072]

[0073] in, Indicates resource pool R i The first candidate power corresponding to the upper PSFCH; P PSFCH,one Indicates power control power; sl-maxTransPower indicates resource pool R i The first maximum power corresponding to the upper PSFCH.

[0074] In the present disclosure, since the first maximum powers of PSFCHs on different resource pools may be different, the first candidate powers corresponding to different resource pools may be the same or different, and the present disclosure does not limit this.

[0075] Step 403: Determine the actual transmission power corresponding to the PSFCH of each resource pool according to the second maximum power and the first candidate power corresponding to the PSFCH of each resource pool.

[0076] In the present disclosure, there may be multiple PSFCHs on a resource pool. Therefore, the network device can determine the total power corresponding to the PSFCHs of all resource pools based on the number of PSFCHs on each resource pool and the first candidate power corresponding to the PSFCHs of each resource pool, and compare the total power corresponding to the PSFCHs of all resource pools with the second maximum power. Based on the comparison result, the actual transmission power corresponding to the PSFCHs of each resource pool is determined.

[0077] For example, if the total power corresponding to all resource pool PSFCHs is less than the second maximum power, it means that the terminal device can support the first candidate power corresponding to each resource pool PSFCH. Then the first candidate power corresponding to each resource pool PSFCH can be used as the actual transmission power corresponding to each resource pool PSFCH.

[0078] Step 404: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool.

[0079] In the embodiment of the present disclosure, step 404 can be implemented in any of the ways in the embodiments of the present disclosure, which is not limited in the embodiment of the present disclosure and will not be described in detail.

[0080] In the embodiment of the present disclosure, for each resource pool, a smaller power can be determined from the power control power and the first maximum power as the first candidate power corresponding to the PSFCH of each resource pool, and the actual transmission power corresponding to the PSFCH of each resource pool is determined based on the second maximum power and the first candidate power corresponding to the PSFCH of each resource pool, and configuration information is sent to the terminal device to configure the transmission power corresponding to each resource pool to the PSFCH on each resource pool. Thus, for each resource pool, based on the smaller power of the power control power of the PSFCH and the first maximum power, and the second maximum power supported by the terminal device, the actual transmission power corresponding to the PSFCH of each resource pool is determined, which can ensure the rationality of the PSFCH transmission power configuration and solve the problem of chaotic power configuration of the terminal device.

[0081] See Figure 5 , Figure 5 This is a flow chart of another method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 5 As shown, the method may include but is not limited to the following steps:

[0082] Step 501: Determine the power control power of the PSFCH on each resource pool.

[0083] Step 502: For each resource pool, determine a smaller power from the power control power and the first maximum power as a first candidate power corresponding to the PSFCH of each resource pool.

[0084] In the embodiment of the present disclosure, steps 501 and 502 can be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0085] Step 503: Determine the first total candidate power corresponding to the PSFCH of the terminal device according to the first candidate powers corresponding to the PSFCHs of the resource pools.

[0086] In the present disclosure, the network device can multiply the number of PSFCHs on each resource pool by the first candidate power corresponding to the PSFCH of each resource pool to obtain the first sub-power corresponding to the PSFCH of each resource pool, and add the first sub-powers corresponding to the PSFCHs of each resource pool to obtain the sum of the first sub-powers of the PSFCHs of each resource pool, and determine the sum of the first sub-powers of the PSFCHs of each resource pool as the first total candidate power corresponding to the PSFCH of the terminal device.

[0087] Based on the example in the above embodiment, the calculation method of the first total candidate power can be shown in the following formulas (3) and (4):

[0088]

[0089]

[0090] in, Indicates resource pool R i The first sub-power on PSFCHR all Indicates the first total candidate power corresponding to the PSFCH of the terminal device.

[0091] Step 504 : When the first total candidate power is less than or equal to the second maximum power, the first candidate power corresponding to the PSFCH of each resource pool is determined as the actual transmission power corresponding to the PSFCH of each resource pool.

[0092] In the present disclosure, the network device can compare the first total candidate power with the second maximum power. If the first total candidate power is less than or equal to the second maximum power, it means that the maximum power supported by the terminal device on PSFCH can meet the transmission requirements of PSFCH on the resource pool. Then the first candidate power corresponding to the PSFCH of each resource pool can be determined as the actual transmission power corresponding to the PSFCH of each resource pool.

[0093] Based on the above example, it is assumed that the second maximum power is P CMAX Indicates that PSFCHR can be all With P CMAX Compare, if the following formula (5) is satisfied, the resource pool R i The first candidate power As a resource pool R i The actual transmission power corresponding to the PSFCH.

[0094] PSFCHR all ≤P CMAX (5)

[0095] Step 505: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool.

[0096] In the embodiment of the present disclosure, step 505 can be implemented in any of the ways in the embodiments of the present disclosure, which is not limited in the embodiment of the present disclosure and will not be described in detail.

[0097] In the embodiment of the present disclosure, the first total candidate power corresponding to the PSFCH of the terminal device can be determined based on the first candidate power corresponding to each resource pool PSFCH. If the first total candidate power is less than or equal to the second maximum power, the first candidate power corresponding to each resource pool PSFCH is determined as the actual transmission power corresponding to each resource pool PSFCH, and configuration information is sent to the terminal device to configure the actual transmission power corresponding to each resource pool for the PSFCH on each resource pool. Thus, when the total candidate power of the PSFCH on all resource pools is less than or equal to the maximum power supported by the terminal device on the PSFCH, the first candidate power corresponding to each resource pool PSFCH can be determined as the actual transmission power corresponding to each resource pool PSFCH, thereby solving the problem of chaotic power configuration of the terminal device.

[0098] See Figure 6 , Figure 6 This is a flow chart of another method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 6 As shown, the method may include but is not limited to the following steps:

[0099] Step 601: Determine the power control power of the PSFCH on each resource pool.

[0100] Step 602: For each resource pool, determine a smaller power from the power control power and the first maximum power as the first candidate power corresponding to the PSFCH of each resource pool.

[0101] Step 603: Determine the first total candidate power corresponding to the PSFCH of the terminal device according to the first candidate powers corresponding to the PSFCHs of the resource pools.

[0102] In the embodiment of the present disclosure, steps 601 to 603 may be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0103] Step 604 : When the first total candidate power is greater than the second maximum power, the first candidate powers corresponding to the PSFCHs of the resource pools are compared to determine the order of the first candidate powers corresponding to the PSFCHs of the resource pools from large to small.

[0104] In the present disclosure, if the first total candidate power is greater than the second maximum power, it means that the maximum power supported by the terminal device on the PSFCH cannot meet the requirements of the first candidate power corresponding to the PSFCH on each resource pool. At this time, the first candidate powers corresponding to the PSFCH of each resource pool can be compared to determine the order of the first candidate powers corresponding to the PSFCH of each resource pool from large to small.

[0105] Step 605: Adjust the first candidate power corresponding to the PSFCH of the first resource pool in descending order to obtain the second candidate power corresponding to the PSFCH of the first resource pool.

[0106] In the present disclosure, the number of resource pools is M, that is, the number of resource pools corresponding to PSFCH is M, where M is a positive integer.

[0107] In the present disclosure, the first resource pool in the order from largest to smallest is the resource pool with the highest first candidate power among the M resource pools.

[0108] In the present disclosure, the first candidate power of the PSFCH on the resource pool with the largest first candidate power may be reduced first to obtain the second candidate power corresponding to the resource pool.

[0109] The present disclosure presets a corresponding adjustment value for each resource pool in the order of the first candidate power from large to small, wherein the larger the first candidate power is, the larger the adjustment value is. The network device can reduce the first candidate power corresponding to the PSFCH of the resource pool according to the adjustment value corresponding to the first resource pool in the order from large to small.

[0110] Optionally, the network device may reduce the first candidate power corresponding to the PSFCH of the first resource pool in descending order to a target value.

[0111] For example, based on the example in the above embodiment, the first candidate power corresponding to the first resource pool PSFCH in the order from large to small can be reduced to the target value P CMAX -10log 10 N.

[0112] Optionally, the network device may also reduce the first candidate power corresponding to the first resource pool PSFCH in the order from large to small to a value greater than the target value P CMAX -10log 10 A certain value of N is set, and then the total candidate power corresponding to the PSFCH of the terminal device is calculated according to the above (3) and (4). If the total candidate power corresponding to the PSFCH of the terminal device is still greater than the second maximum power, then continue to reduce it until it is adjusted to the target value.

[0113] Step 606: Determine a second total candidate power corresponding to the PSFCH of the terminal device based on the second candidate power and the first candidate powers corresponding to the PSFCHs of other resource pools in the M resource pools.

[0114] In the present disclosure, the network device can multiply the second candidate power by the number of PSFCHs on the first resource pool in descending order to obtain the second sub-power corresponding to the PSFCH of the resource pool, and for other resource pools among the M resource pools except the resource pool with the highest first candidate power, obtain the first sub-power based on the product of the number of PSFCHs on other resource pools and the first candidate power, and add the second sub-power to the first sub-power corresponding to the PSFCH of other resource pools to obtain the second total candidate power corresponding to the PSFCH of the terminal device.

[0115] That is, after reducing the first candidate power corresponding to the PSFCH of the first resource pool in order from large to small to the second candidate power, the second total candidate power corresponding to the PSFCH of the terminal device can be calculated using the above formulas (3) and (4).

[0116] Step 607, when the second total candidate power is greater than the second maximum power, adjust the first candidate power corresponding to the PSFCH of the second resource pool in the order from large to small, until the first candidate power corresponding to the PSFCH of the i-th resource pool in the order from large to small is adjusted, and the second total candidate power corresponding to the PSFCH of the terminal device is less than or equal to the second maximum power.

[0117] Among them, the second resource pool in the order from largest to smallest is the resource pool with the second highest power among the first candidate of the M resource pools.

[0118] In the present disclosure, after adjusting the first candidate power corresponding to the resource pool with the largest first candidate power, if the second total candidate power corresponding to the PSFCH of the terminal device is greater than the second maximum power, the first candidate power corresponding to the PSFCH of the second resource pool in the order from large to small can be reduced, and the second total candidate power corresponding to the PSFCH of the terminal device can be calculated. If the second total candidate power corresponding to the PSFCH of the terminal device is still greater than the second maximum power, the first candidate power corresponding to the PSFCH of the third resource pool in the order from large to small can be further reduced, until the first candidate power corresponding to the PSFCH of the i-th resource pool in the order from large to small is reduced, and the second total candidate power corresponding to the PSFCH of the terminal device is less than or equal to the second maximum power.

[0119] Here, i can be a positive integer less than or equal to M.

[0120] In the present disclosure, the method of adjusting the first candidate power corresponding to PSFCH of other resource pools is similar to the method of adjusting the first candidate power corresponding to PSFCH of the first resource pool in the order from large to small, so it will not be repeated here.

[0121] In step 608, the second candidate powers corresponding to the PSFCHs of the first i resource pools in descending order are determined as the actual transmission powers corresponding to the PSFCHs of the first i resource pools.

[0122] In the present disclosure, the second candidate power obtained after adjusting the first i resource pools in order from large to small can be used as the actual transmission power corresponding to the PSFCH of the first i resource pools.

[0123] For example, if M is 4 and i is 2, the resource pool with the highest first candidate power can be adjusted to obtain the second candidate power, which is used as the actual transmission power corresponding to the PSFCH of the resource pool with the highest first candidate power. The resource pool with the second highest first candidate power can be adjusted to obtain the second candidate power, which is used as the actual transmission power corresponding to the PSFCH of the resource pool with the second highest first candidate power.

[0124] In step 609, the first candidate powers corresponding to the PSFCHs of the i+1th to Mth resource pools, respectively, in descending order, are determined as the actual transmission powers corresponding to the PSFCHs of the i+1th to Mth resource pools, respectively.

[0125] In the present disclosure, the first candidate powers corresponding to the PSFCHs of the i+1th to Mth resource pools in order from large to small are not adjusted, and the first candidate powers corresponding to the PSFCHs of the i+1th to Mth resource pools in order from large to small can be determined as the actual transmission powers corresponding to the PSFCHs of the i+1th to Mth resource pools.

[0126] Step 610: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool.

[0127] In the embodiment of the present disclosure, step 610 can be implemented in any of the ways in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0128] In the embodiment of the present disclosure, the number of resource pools is M. If the first total candidate power is greater than the second maximum power, the first candidate powers corresponding to the resource pool PSFCHs can be adjusted in descending order according to the first candidate powers, until the first candidate power corresponding to the PSFCH of the i-th resource pool in the descending order is adjusted, and the second total candidate power corresponding to the PSFCH of the terminal device is less than or equal to the second maximum power. For the resource pool whose first candidate power is adjusted, the second candidate power obtained after adjustment can be used as the actual transmission power corresponding to the resource pool PSFCH. For the resource pool whose first candidate power is not adjusted, the first candidate power can be used as the actual transmission power corresponding to the PSFCH of these resource pools, thereby solving the problem of chaotic power configuration of the terminal device.

[0129] See Figure 7 , Figure 7 This is a flow chart of another method for configuring PSFCH transmission power provided by an embodiment of the present disclosure, which is executed by a network device. Figure 7 As shown, the method may include but is not limited to the following steps:

[0130] Step 701: Determine the power control power of the PSFCH on each resource pool.

[0131] Step 702: For each resource pool, determine a smaller power from the power control power and the first maximum power as the first candidate power corresponding to the PSFCH of each resource pool.

[0132] Step 703: Determine the first total candidate power corresponding to the PSFCH of the terminal device according to the first candidate powers corresponding to the PSFCHs of the resource pools.

[0133] In the embodiment of the present disclosure, steps 701 to 703 can be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0134] Step 704 : When the first total candidate power is greater than the second maximum power, adjust the first candidate power corresponding to the target resource pool PSFCH in each resource pool to obtain a third candidate power corresponding to the target resource pool PSFCH.

[0135] In the present disclosure, if the first total candidate power is greater than the second maximum power, the first candidate power corresponding to the PSFCH of the target resource pool in each resource pool can be reduced to the third candidate power so that the third total candidate power corresponding to the PSFCH of the terminal device is less than or equal to the second maximum power.

[0136] Among them, the third total candidate power can be determined based on the third candidate power and the first candidate power corresponding to the PSFCH of other resource pools in each resource pool. The calculation method of the third total candidate power is similar to the calculation method of the above-mentioned first total candidate power, so it will not be repeated here.

[0137] In the present disclosure, the target resource pool may be one or more resource pools among the resource pools, and the present disclosure does not limit this.

[0138] Optionally, if the first total candidate power is greater than the second maximum power, one or more resource pools can be randomly selected from each resource pool as the target resource, and the first candidate power corresponding to the target resource PSFCH can be reduced to obtain the third candidate power corresponding to the target resource pool PSFCH.

[0139] Optionally, if the first total candidate power is greater than the second maximum power, the first one or more resource pools with the highest first candidate power in each resource pool can also be used as the target resource pool, and the first candidate power corresponding to the target resource PSFCH can be reduced to obtain the third candidate power corresponding to the target resource pool PSFCH.

[0140] Step 705: Determine the third candidate power corresponding to the PSFCH of the target resource pool as the actual transmission power corresponding to the PSFCH of the target resource pool.

[0141] In the present disclosure, for the target resource pool, the third candidate power obtained by adjusting the first candidate power corresponding to the PSFCH of the target resource pool may be used as the actual transmission power corresponding to the PSFCH of the target resource pool.

[0142] Step 706: Determine the first candidate power corresponding to the PSFCH of the other resource pool as the actual transmission power corresponding to the PSFCH of the other resource pool.

[0143] In the present disclosure, for other resource pools except the target resource pool in each resource pool, the first candidate power corresponding to the PSFCH of the other resource pool may be used as the actual transmission power corresponding to the PSFCH of the other resource pool.

[0144] Step 707: Send configuration information to the terminal device, where the configuration information is used to configure the actual transmission power corresponding to each resource pool to the PSFCH on each resource pool.

[0145] In the embodiment of the present disclosure, step 707 can be implemented in any of the ways in the embodiments of the present disclosure, which is not limited in the embodiment of the present disclosure and will not be described in detail.

[0146] In an embodiment of the present disclosure, if the first total candidate power is greater than the second maximum power, the first candidate power corresponding to the target resource pool PSFCH in each resource pool can be adjusted to obtain the third candidate power corresponding to the target resource pool PSFCH, wherein the third total candidate power corresponding to the PSFCH of the terminal device is less than or equal to the second maximum power, and the third total candidate power is determined based on the third candidate power corresponding to the target resource pool PSFCH and the first candidate power corresponding to the PSFCH of other resource pools in each resource pool, and the third candidate power corresponding to the target resource pool PSFCH is determined as the actual transmission power corresponding to the target resource pool PSFCH, and the first candidate power corresponding to the PSFCH of other resource pools is determined as the actual transmission power corresponding to the PSFCH of other resource pools, thereby solving the problem of chaotic power configuration of terminal devices.

[0147] To facilitate understanding of the method for configuring the PSFCH transmission power of the present disclosure, the following embodiments are used to illustrate the method.

[0148] The network equipment can configure the time-frequency resources for the PSFCH in the sidelink transmission of the terminal device. For example, at a PSFCH transmission moment, that is, a sidelink frame containing PSFCH has N PSFCHs transmitted simultaneously, among which, there are R resource pools for these N PSFCHs. i There is a K i PSFCH transmission, satisfying

[0149]

[0150] The network equipment can calculate the power control power P according to the above formula (1): PSFCH,one , and adopt is the first power and P PSFCH,one The smaller value in , that is, the above formula (2).

[0151] The network device can also receive the maximum power P supported by the terminal device on the PSFCH reported by the terminal device. CMAX , the network equipment can ensure that the total power of PSFCH configured on each resource pool is less than P CMAX , which also satisfies the above formula (5).

[0152] If the network device calculates the total power of the PSFCH configured on each resource pool Greater than P CMAX , you can first reduce The power of all PSFCHs in the highest resource pool, up to the corresponding If the above formula (5) is still not possible, you can continue to reduce The power of PSFCH in the second highest resource pool, until the corresponding By analogy, the network device completes the power configuration for the PSFCH. The network device can configure the determined actual transmission power of the PSFCH to the terminal device. Specifically, for PSFCHs belonging to the same resource pool, the network device can configure the same actual transmission power. The terminal device can perform corresponding PSFCH transmission based on the actual transmission power configuration of the PSFCH issued by the network device.
