[0107] In the related technology, the terminal selects a carrier to transmit SL signals and uplink signals. Since the selection of resources on each carrier is independent, there may be time domain overlap in the transmission of SL signals and uplink signals. However, in the SL power, the terminal requires that the total power of all transmissions of the terminal does not exceed the power threshold.

[0108] If there is time domain overlap between the transmission of multiple SL signals and at least one uplink signal, and the transmission power on the overlapping resources of the time domain overlap is greater than the power threshold, how to control the transmission power of multiple SL signals and at least one uplink signal on the overlapping resources to ensure that the transmission power is less than or equal to the power threshold is an urgent problem to be solved.

[0109] Based on this, in an embodiment of the present disclosure, a power control method, a terminal, and a network device are provided, wherein the method executed by the terminal includes: determining that there is a time domain overlap in the transmission of a first type of signal and a second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than a power threshold, wherein the first type of signal is a plurality of SL signals, the plurality of SL signals are located on a plurality of carriers, and the second type of signal is one or more uplink signals; according to the priority of the first type of signal and the priority of the second type of signal, the transmission power of the first type of signal and the second type of signal on the overlapping resources is determined. Thus, when the sum of the power transmitted by the first type of signal and the second type of signal on the overlapping resources of the time domain overlap is greater than the power threshold, the terminal can determine the transmission power of the first type of signal and the second type of signal on the overlapping resources according to the priority of the first type of signal and the priority of the second type of signal, so as to meet the requirement that the transmission power of the first type of signal and the second type of signal on the overlapping resources is less than or equal to the power threshold, thereby avoiding signal interference and ensuring the normal communication.

[0150] In an embodiment of the present disclosure, the terminal can determine the time domain interval and power in which multiple SL signals on multiple carriers are transmitted, as well as the time domain interval and power in which one or more uplink signals on one or more carriers are transmitted. Thus, the terminal can determine whether there is time domain overlap in the transmission of multiple SL signals and uplink signals, and if there is time domain overlap, whether the sum of the powers transmitted on the overlapping resources of the time domain overlap is greater than the power threshold.

[0151] In an embodiment of the present disclosure, when the terminal determines that there is time domain overlap in the transmission of a first type of signal and a second type of signal, and the sum of the powers transmitted on the overlapping resources of the time domain overlap is greater than a power threshold, the terminal can determine the transmission power of the first type of signal and the second type of signal on the overlapping resources based on the priority of the first type of signal and the priority of the second type of signal.

[0155] In some embodiments, the terminal adjusts the power of the first type signal and / or the second type signal transmitted on the overlapping resources based on the priority of the first type signal and the priority of the second type signal. The terminal may adjust the power of one or more SL signals of the first type signal transmitted on the overlapping resources, or may also adjust the power of one or more uplink signals of the second type signal transmitted on the overlapping resources, or may also adjust the power of one or more SL signals of the first type signal and one or more uplink signals of the second type signal transmitted on the overlapping resources.

[0156] In some embodiments, the terminal adjusts the power of the first type signal and / or the second type signal transmitted on the overlapping resources according to the priority of the first type signal and the priority of the second type signal, including: adjusting the power of the first type signal and / or the second type signal transmitted on the overlapping resources according to the priority value of the SL signal with the highest priority among the first type signals and the priority value corresponding to the second type signal; or adjusting the power of the first type signal and / or the second type signal transmitted on the overlapping resources according to the priority value of the SL signal with the highest priority among the first type signals and the first priority value corresponding to the second type signal.

[0157] In one possible implementation, the terminal may adjust the power of the first type signal and / or the second type signal transmitted on overlapping resources based on the priority value of the SL signal with the highest priority in the first type signal and the priority value corresponding to the second type signal.

[0158] In some embodiments, the priority value corresponding to the second type signal may be the priority value of one or more uplink signals of the second type signal.

[0159] In another possible implementation, the terminal may adjust the power of the first type signal and / or the second type signal transmitted on the overlapping resources based on the priority value of the SL signal with the highest priority in the first type signal and the first priority value corresponding to the second type signal.

[0160] In some embodiments, the first priority value corresponding to the second type signal may determine a first priority value corresponding to the entirety of one or more uplink signals of the second type signal.

[0161] In some embodiments, the terminal adjusts the power of the first type signal and / or the second type signal transmitted on overlapping resources, including: determining that the priority value of the SL signal with the highest priority among the first type signals is greater than the priority value corresponding to the second type signal, or the priority value of the SL signal with the highest priority among the first type signals is greater than the first priority value, and adjusting the power of the first type signal transmitted on overlapping resources.

[0162] In one possible implementation, the terminal determines that the priority value of the SL signal with the highest priority among the first type signals is greater than the priority value corresponding to the second type signal, and adjusts the power of the first type signal transmitted on the overlapping resources.

[0163] In another possible implementation, the terminal determines that the priority value of the SL signal with the highest priority among the first type of signals is greater than the first priority value, and adjusts the power of the first type of signals transmitted on the overlapping resources.

[0164] In some embodiments, the terminal adjusts the power of the first type of signal transmitted on overlapping resources, including: according to the priority value corresponding to each SL signal in the first type of signal, reducing the power of the corresponding signal or giving up the transmission of the corresponding signal in order from high to low priority values, wherein the corresponding signal is the signal corresponding to the priority value; or according to the priority value corresponding to each SL signal in the first type of signal, reducing the power of the corresponding signal to the minimum power threshold in order from high to low priority values, wherein the corresponding signal is the signal corresponding to the priority value.

[0165] In one possible implementation, the terminal reduces the power of the corresponding signal or abandons the transmission of the corresponding signal according to the priority value corresponding to each SL signal in the first type signal, in descending order of priority value, where the corresponding signal is the signal corresponding to the priority value.

[0166] In another possible implementation, the terminal reduces the power of the corresponding signal to the minimum power threshold in sequence from high to low according to the priority value corresponding to each SL signal in the first type of signal, where the corresponding signal is the signal corresponding to the priority value.

[0167] In some embodiments, the terminal may determine the lowest power threshold based on a pre-definition, or may also determine the lowest power threshold based on a pre-configuration.

[0168] Exemplarily, the terminal may determine the lowest power threshold based on an instruction from the network device.

[0169] Exemplarily, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than the power threshold, the first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers, wherein the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, the priority value of the SL signal on carrier #3 is 4, the priority value of the uplink signal on carrier #4 is 1, and the priority value of the uplink signal on carrier #5 is 1.

[0170] Among them, the SL signal with the highest priority in the first type of signal is the SL signal on carrier #1, and the priority value of the SL signal on carrier #1 is 2, which is greater than the priority value corresponding to the second type of signal. It is determined that the power of the first type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0171] Among them, the power of the first type of signal transmitted on the overlapping resources can be adjusted by reducing the power of the corresponding signal or abandoning the transmission of the corresponding signal according to the priority value corresponding to each SL signal in the first type of signal, from high to low, wherein the corresponding signal is the signal corresponding to the priority value; or the power of the corresponding signal can be reduced to the minimum power threshold according to the priority value corresponding to each SL signal in the first type of signal, from high to low, wherein the corresponding signal is the signal corresponding to the priority value.

[0172] For example, the first type of signal is in the following order from high to low priority value: SL signal on carrier #3 with a priority value of 4, SL signal on carrier #2 with a priority value of 3, and SL signal on carrier #1 with a priority value of 2.

[0173] First, the power of the SL signal on carrier #3 transmitted on the overlapping resources is adjusted. If the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold at this time, the power of other signals transmitted on the overlapping resources does not need to be adjusted.

[0174] If at this time the power of the first type signal and the second type signal transmitted on the overlapping resources is still greater than the power threshold, the power of the SL signal on carrier #2 transmitted on the overlapping resources is adjusted. If at this time the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold, the power of other signals transmitted on the overlapping resources does not need to be adjusted.

[0175] The power of the first type signal transmitted on the overlapping resources is adjusted according to the above rule until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0176] Exemplarily, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than the power threshold. The first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers, wherein the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, and the priority value of the SL signal on carrier #3 is 4. The first priority value corresponding to the second type of signal is 1.

[0177] Among them, the priority value of the SL signal with the highest priority in the first type of signal is 2. If it is determined that the priority value of the SL signal with the highest priority in the first type of signal is greater than the first priority value, it is determined that the power of the first type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0178] In some embodiments, the terminal adjusts the power of the first type signal and / or the second type signal transmitted on overlapping resources, including: determining that the priority value of the SL signal with the highest priority among the first type signals is less than the priority value corresponding to the second type signal, or the priority value of the SL signal with the highest priority among the first type signals is less than the first priority value, and adjusting the power of the second type signal transmitted on overlapping resources.

[0179] In one possible implementation, the terminal determines that the priority value of the SL signal with the highest priority among the first type of signals is smaller than the priority value corresponding to the second type of signal, and adjusts the transmission power of the second type of signal on the overlapping resources.

[0180] In a possible implementation, the terminal determines that the priority value of the SL signal with the highest priority among the first type of signals is less than the first priority value, and adjusts the power of the second type of signal transmitted on the overlapping resources.

[0181] Exemplarily, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than the power threshold, the first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers, wherein the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, the priority value of the SL signal on carrier #3 is 4, the priority value of the uplink signal on carrier #4 is 5, and the priority value of the uplink signal on carrier #5 is 5.

[0182] Among them, the priority value of the SL signal with the highest priority in the first type of signal is 2. If it is determined that the priority value of the SL signal with the highest priority in the first type of signal is less than the priority value corresponding to the second type of signal, the power of the second type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0183] Exemplarily, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than the power threshold. The first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers, wherein the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, the priority value of the SL signal on carrier #3 is 4, and the first priority value corresponding to the second type of signal is 5.

[0184] Among them, the priority value of the SL signal with the highest priority in the first type of signal is 2. If it is determined that the priority value of the SL signal with the highest priority in the first type of signal is less than the first priority value, the power of the second type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0185] In some embodiments, the terminal adjusts the power of the second type signal transmitted on the overlapping resources, including: reducing the power of the uplink signal in the second type signal; or giving up transmitting the uplink signal in the second type signal.

[0186] In a possible implementation manner, the terminal reduces the power of the uplink signal in the second type of signal.

[0187] In a possible implementation manner, the terminal reduces the power of an uplink signal in the second type of signal.

[0188] In a possible implementation manner, the terminal reduces the power of multiple uplink signals in the second type of signal.

[0189] In a possible implementation manner, the terminal gives up transmitting the uplink signal in the second type of signal.

[0190] In a possible implementation manner, the terminal gives up transmitting an uplink signal in the second type of signal.

[0191] In a possible implementation manner, the terminal gives up transmitting multiple uplink signals in the second type of signal.

[0192] In the embodiment of the present disclosure, the terminal reduces the power of the uplink signal in the second type of signal. This can be based on terminal implementation and the terminal can independently determine whether to reduce the power of the uplink signal in the second type of signal.

[0193] In the embodiment of the present disclosure, the terminal may abandon transmission of one or more uplink signals in the second type of signal based on terminal implementation and independently determine to abandon transmission of one or more uplink signals in the second type of signal.

[0194] In some embodiments, adjusting the power of the first type signal and / or the second type signal transmitted on the overlapping resources according to the priority of the first type signal and the priority of the second type signal includes:

[0195] Sort the priority value corresponding to each SL signal in the first type of signal and the priority value corresponding to each uplink signal in the second type of signal, and reduce the power of the corresponding signal or abandon the transmission of the corresponding signal in descending order of priority value, where the corresponding signal is the signal corresponding to the priority value; or

[0196] Sort the priority value corresponding to each SL signal in the first type of signal and the priority value corresponding to each uplink signal in the second type of signal, and reduce the power of the corresponding signals to the lowest power threshold in descending order of priority value, where the corresponding signal is the signal corresponding to the priority value; or

[0197] Sort the priority value corresponding to each SL signal in the first type of signal and the first priority value corresponding to the second type of signal, and reduce the power of the corresponding signal or abandon the transmission of the corresponding signal in descending order of priority value, where the corresponding signal is the signal corresponding to the priority value; or

[0198] Sort the priority value corresponding to each SL signal in the first type signal and the first priority value corresponding to the second type signal, and reduce the power of the corresponding signal to the lowest power threshold in order from high to low priority value, where the corresponding signal is the signal corresponding to the priority value.

[0199] In one possible implementation, the terminal sorts the priority value corresponding to each SL signal in the first type signal and the priority value corresponding to each uplink signal in the second type signal, and reduces the power of the corresponding signal or abandons the transmission of the corresponding signal in order from high to low priority value until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0200] In another possible implementation, the terminal sorts the priority values ​​corresponding to each SL signal in the first type signal and the priority values ​​corresponding to each uplink signal in the second type signal, and reduces the power of the corresponding signals to the minimum power threshold in order from high to low priority values, until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0201] Exemplarily, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources of the time domain overlap is greater than the power threshold, the first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers, wherein the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, the priority value of the SL signal on carrier #3 is 4, the priority value of the uplink signal on carrier #4 is 5, and the priority value of the uplink signal on carrier #5 is 1.

[0202] Among them, the priority value corresponding to each SL signal in the first type of signal and the priority value corresponding to each uplink signal in the second type of signal are sorted from high to low according to the priority value, 5>4>3>2>1, and the corresponding sorting is, first is the uplink signal on carrier #4, second is the SL signal on carrier #3, third is the SL signal on carrier #2, fourth is the SL signal on carrier #1, and fifth is the uplink signal on carrier #5.

[0203] Based on this, according to the determined order, the power of the corresponding signal is reduced or the transmission of the corresponding signal is abandoned in sequence until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold; or according to the determined order, the power of the corresponding signal is reduced to the lowest power threshold in sequence until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0208] Based on this, according to the determined order, the power of the corresponding signal is reduced or the transmission of the corresponding signal is abandoned in sequence until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold; or according to the determined order, the power of the corresponding signal is reduced to the lowest power threshold in sequence until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0211] In some embodiments, the terminal receives second indication information sent by the network device, where the second indication information is used to indicate the first parameter.

[0212] In the embodiment of the present disclosure, the terminal may determine the first parameter based on the second indication information sent by the network device, thereby determining the first priority value corresponding to the second type of signal.

[0213] In some embodiments, the first parameter is sl-PriorityThreshold-UL-URLLC.

[0214] In some embodiments, the uplink signal in the second type signal is PUSCH and the priority value is 1, or the uplink signal in the second type signal is PUCCH and the priority value is 1, the above method also includes: the terminal determines that the first parameter is not configured; determines that the priority of the second type signal is higher than the priority of the first type signal, and determines to adjust the power of the first type signal transmitted on the overlapping resources.

[0215] In an embodiment of the present disclosure, when the uplink signal in the second type of signal is PUSCH and the priority value is 1, or when the uplink signal in the second type of signal is PUCCH and the priority value is 1, the terminal determines that the first parameter is not configured, and can determine that the priority of the second type of signal is higher than the priority of the first type of signal, and determine to adjust the power of the first type of signal transmitted on the overlapping resources.

[0216] In some embodiments, the second type signal does not contain a PUSCH with a priority value of 1, or the second type signal does not contain a PUCCH with a priority value of 1, and the above method also includes: the terminal determines a second parameter of the configuration; and determines the first priority value as the second parameter.

[0218] In some embodiments, the terminal receives third indication information sent by the network device, where the third indication information is used to indicate the second parameter.

[0219] In the embodiment of the present disclosure, the terminal may determine the second parameter based on the third indication information sent by the network device, thereby determining the first priority value corresponding to the second type of signal.

[0220] In some embodiments, the second parameter is sl-PriorityThreshold.

[0221] In some embodiments, multiple SL signals in the first type signal are all PSSCHs, and the above method also includes: the terminal determines to replace the priority value of the SL signal with the highest priority in the first type signal with a second priority value, wherein the second priority value is the priority value corresponding to the logical channel with the highest priority in the carrier used by multiple SL signals in the first type signal; determines to replace the priority value corresponding to the second type signal with a second parameter, or determines that the first priority value corresponding to the second type signal is the second parameter.

[0222] In an embodiment of the present disclosure, multiple SL signals in the first type of signal are all PSSCHs, and the terminal can determine to replace the priority value of the SL signal with the highest priority in the first type of signal with a second priority value, and the second priority value is the priority value corresponding to the logical channel with the highest priority in the carrier used by multiple SL signals in the first type of signal.

[0223] In this case, the terminal may determine to replace the priority value corresponding to the second type signal with the second parameter, or determine the first priority value corresponding to the second type signal as the second parameter.

[0224] Based on this, the terminal may adjust the transmission power of the first type signal and / or the second type signal on the overlapping resources according to the second priority value and the second parameter.

[0225] In which, when the second priority value is greater than the second parameter, the power of the first type of signal transmitted on the overlapping resources is adjusted, for example: according to the priority value corresponding to each SL signal in the first type of signal, the power of the corresponding signal is reduced or the transmission of the corresponding signal is abandoned in sequence from high to low priority values, wherein the corresponding signal is the signal corresponding to the priority value; or according to the priority value corresponding to each SL signal in the first type of signal, the power of the corresponding signal is reduced to the lowest power threshold in sequence from high to low priority values, wherein the corresponding signal is the signal corresponding to the priority value.

[0226] When the second parameter is greater than the second priority value, the power of the second type signal transmitted on the overlapping resources is adjusted, for example: the power of the uplink signal in the second type signal is reduced; or the transmission of the uplink signal in the second type signal is abandoned.

[0227] In some embodiments, multiple SL signals in the first type signal are all PSSCHs, and the above method also includes: the terminal determines to replace the priority value corresponding to each SL signal in the first type signal with a second priority value, wherein the second priority value is the priority value corresponding to the logical channel with the highest priority in the carrier used by the multiple SL signals in the first type signal; determines to replace the priority value corresponding to the second type signal with a second parameter, or determines that the first priority value corresponding to the second type signal is the second parameter.

[0228] In an embodiment of the present disclosure, multiple SL signals in the first type of signal are all PSSCHs, and the terminal can determine to replace the priority value corresponding to each SL signal in the first type of signal with a second priority value, and the second priority value is the priority value corresponding to the logical channel with the highest priority in the carrier used by the multiple SL signals in the first type of signal.

[0229] In this case, the terminal may determine the configured second parameter and determine to replace the priority value corresponding to the second type signal with the second parameter, or determine the first priority value corresponding to the second type signal as the second parameter.

[0230] Based on this, the terminal may adjust the transmission power of the first type signal and / or the second type signal on the overlapping resources according to the second priority value and the second parameter.

[0231] Among them, the second priority value and the second parameter are sorted, and the power of the corresponding signal is reduced or the transmission of the corresponding signal is abandoned in sequence according to the priority value from high to low, or the power of the corresponding signal is reduced to the lowest power threshold in sequence according to the priority value from high to low.

[0232] Exemplarily, the terminal determines that the first parameter sl-PriorityThreshold-UL-URLLC is configured, and the first parameter is 5. The terminal can determine that the first priority value corresponding to the second type of signal is the first parameter, that is, 5.

[0233] Among them, there is time domain overlap in the transmission of the first type of signal and the second type of signal, and the sum of the power transmitted on the overlapping resources in the time domain overlap is greater than the power threshold. The first type of signal is 3 SL signals on 3 carriers, and the second type of signal is 2 uplink signals on 2 carriers. Among them, the priority value of the SL signal on carrier #1 is 2, the priority value of the SL signal on carrier #2 is 3, and the priority value of the SL signal on carrier #3 is 4. The first priority value corresponding to the second type of signal is the first parameter, that is, 5.

[0234] In one possible implementation, the priority value of the SL signal with the highest priority in the first type of signal is 2. If it is determined that the priority value of the SL signal with the highest priority in the first type of signal is less than the first parameter, the power of the second type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0235] In another possible implementation, the priority value corresponding to each SL signal in the first type of signal and the first parameter corresponding to the second type of signal are sorted from high to low according to the priority value, 5>4>3>2, and the corresponding sorting is: first, the two uplink signals on the two carriers of the second type of signal, second, the SL signal on carrier #3, third, the SL signal on carrier #2, and fourth, the SL signal on carrier #1. Based on this, according to the determined sorting, the power of the corresponding signals is sequentially reduced or the transmission of the corresponding signals is abandoned until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold; or according to the determined sorting, the power of the corresponding signals is sequentially reduced to the lowest power threshold until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0236] Exemplarily, multiple SL signals in the first type of signal are all PSSCH, and the terminal determines to replace the priority value corresponding to each SL signal in the first type of signal with a second priority value. The second priority value is the priority value corresponding to the logical channel with the highest priority in the carrier used by the multiple SL signals in the first type of signal, for example, 3. That is, the terminal can determine that the priority value corresponding to each SL signal in the first type of signal is the second priority value 3; the terminal determines that the configured second parameter sl-PriorityThreshold is 2, and determines to replace the priority value corresponding to the second type of signal with the second parameter 2.

[0237] In one possible implementation, the priority value of the SL signal with the highest priority in the first type of signal is 3, and the corresponding priority value of the second type of signal is 2. It is determined that the priority value of the SL signal with the highest priority in the first type of signal is greater than the priority value corresponding to the second type of signal. It is determined that the power of the first type of signal transmitted on the overlapping resources is adjusted until the power of the first type of signal and the second type of signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0238] In another possible implementation, the priority value corresponding to each SL signal in the first type signal is the second priority value 3, and the priority value corresponding to the second type signal is replaced by the second parameter 2. The power of the corresponding signal is reduced or the transmission of the corresponding signal is abandoned in sequence from high to low priority values. First, the power of the SL signal is reduced or the transmission of the SL signal is abandoned until the power of the first type signal and the second type signal transmitted on the overlapping resources is less than or equal to the power threshold.

[0239] S203 : The terminal transmits the first type signal and the second type signal in the time slot or symbol where the overlapping resource is located according to the determined transmission power of the first type signal and the second type signal in the overlapping resource.

[0240] It can be understood that the overlapping resources where the first type signal and the second type signal overlap in the time domain may be some orthogonal frequency division multiplexing (OFMD) symbols.

[0242] In the embodiment of the present disclosure, the terminal may transmit the first type signal and the second type signal on the symbol where the overlapping resource is located according to the determined transmission power of the first type signal and the second type signal on the overlapping resource.

[0243] Exemplarily, if the first type signal and the second type signal have overlapping time domain resources on OFDM symbols 4, 5, 6, and 7 of time slot #1, the terminal transmits the first type signal and the second type signal on the entire time slot #1 (i.e., on all OFDM symbols of time slot #1) according to the determined transmission power of the first type signal and the second type signal on the overlapping resources.

[0244] Exemplarily, if the first type signal and the second type signal have time domain resource overlap on OFDM symbols 4, 5, 6, and 7 of time slot 1, the terminal only transmits the first type signal and the second type signal on the overlapping OFDM symbols (i.e., OFDM symbols 4, 5, 6, and 7) of time slot 1 according to the determined transmission power of the first type signal and the second type signal on the overlapping resources.

[0375] To facilitate understanding of the embodiments of the present disclosure, the following exemplary embodiments are provided.

[0376] In an exemplary embodiment, in Sidelink CA, resource selection for each carrier is independent, and the resource pool is defined on the carrier. The terminal first selects the carrier and then the resource. Therefore, it is possible that the terminal selects time-domain overlapping resources on multiple sidelink carriers.

[0377] Sidelink power control requires that the total power of all sidelink transmissions from a terminal does not exceed a power threshold (hereinafter referred to as Pcmax). If the signal transmitted on one sidelink carrier overlaps with the uplink (UL) signal on another carrier in the time domain, and the total power exceeds Pcmax, the power of the lower-priority SL signal or uplink signal can be reduced based on priority comparison.

[0378] In sidelink CA, multiple SL signals transmitted on multiple sidelink carriers will overlap with uplink signals transmitted on uplink carriers in the time domain. However, when multiple SL signals and uplink signals of the terminal are sent simultaneously on the overlapping time domain resources, the total power will exceed Pcmax. In this case, how the terminal performs uplink power control requires a relevant solution.

[0379] Solution 1: Take the lowest priority value among multiple SL signals transmitted on multiple SL carriers with overlapping time domain resources as the priority of the entire SL, and use this priority value to compare with the priority value of the UL signal. The following method is used to reduce power:

[0380] Case 1: When the UL signal priority is lower than the SL signal priority, the SL signal power is reduced. The following methods are used:

[0381] Method 1: First, among multiple SL carriers, the power of the SL signal transmitted on the SL carrier with the highest priority value is reduced or the transmission is abandoned (dropped). If the total transmission power of the terminal on the overlapping time domain resources still exceeds Pcmax, the power of the SL signal transmitted on the SL carrier with the second highest priority value is reduced or the transmission is abandoned (dropped). This process is repeated until the total transmission power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0382] Method 2: First, on multiple SL carriers, the power of the SL signal transmitted on the SL carrier with the highest priority value is reduced, but the power is not less than the minimum power threshold. At this time, the total transmission power of the terminal on the overlapping time domain resources still exceeds Pcmax. Then, the power of the SL signal transmitted on the SL carrier with the second highest priority value is reduced, and the power is not less than the minimum power threshold. Repeat this process until the total transmission power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0383] In some embodiments, the minimum power threshold is predefined or preconfigured.

[0384] In some embodiments, Pcmax is predefined, or preconfigured.

[0385] Case 2: When the UL signal priority is greater than the SL signal priority, reduce the UL signal power:

[0386] For example, if sidelink CA uses two carriers, the SL signal priority value on carrier 1 is 2, the SL signal priority value on carrier 2 is 4, and the UL signal priority value is 3, then the SL signal priority value 2 is used as the priority value of the entire SL signal and compared with the priority value of the UL signal. If 2<3 is obtained, the power of the UL signal is reduced until the total power does not exceed Pcmax.

[0387] Solution 2: Prioritize the SL signal transmitted on each SL carrier and the UL signal transmitted on each UL carrier, and reduce power using the following method:

[0388] Method 1: Reduce the power or abandon the transmission (i.e., drop) of the signal with the highest priority value in the UL carrier and the SL carrier. When the total transmission power of the terminal on the overlapping time domain resources still exceeds Pcmax, reduce the power or drop the signal with the second highest priority value. Follow this rule until the total transmission power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0389] Method 2: Reduce the power of the signal with the highest priority value in the UL carrier and the SL carrier, but the power is not less than the minimum power threshold. When the total transmit power of the terminal on the overlapping time domain resources still exceeds Pcmax, reduce the power of the signal with the second highest priority value, but the power is not less than the minimum power threshold. Follow this rule until the total transmit power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0390] For example, if SL uses two carriers, the SL signal priority value on carrier 1 is 2, the SL signal priority value on carrier 2 is 4, and the UL signal priority value is 3, then the signals transmitted on the three carriers are prioritized. If 2<3<4, the SL signal transmitted on SL carrier 2 is first power-reduced or dropped. If the power still exceeds the maximum power, the UL signal is power-reduced or dropped. This rule is repeated until the total transmit power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0391] For example, if SL uses 2 carriers, the priority value of the SL signal on SL carrier 1 is 2, and the priority value of the SL signal on SL carrier 2 is 4, and UL uses 2 carriers, the priority value of the UL signal transmitted on UL carrier 1 is 3, and the priority value of the UL signal transmitted on UL carrier 2 is 5, then the signals transmitted on the 4 carriers are prioritized, 2<3<4<5, then the power of the UL signal transmitted on UL carrier 2 is first reduced or dropped, if it still exceeds the maximum power, the power of the SL signal on SL carrier 2 is reduced, and this rule is followed until the total transmit power of the terminal on the overlapping time domain resources does not exceed Pcmax.

[0392] In some embodiments, the SL signal may include: a PSFCH transmission signal and an S-SSB transmission signal.

[0393] In some embodiments, the PSFCH priority is determined by the corresponding PSSCH.

[0394] In some embodiments, the priority of S-SSB is determined by higher layer (pre)configuration.

[0395] In some embodiments, the priority values ​​of PSSCH and PSCCH are indicated by the priority value field in the first stage SCI.

[0396] In some embodiments, the UL signal may include one or more UL signals on one or more UL carriers.

[0397] In some embodiments, the UL signal is a PUSCH and the priority value is 1, or the UL signal is a PUCCH and the priority value is 1.

[0398] Using solution 1, the priority comparison between SL and UL signals is specifically performed as follows:

[0399] Case 1: If the first parameter sl-PriorityThreshold-UL-URLLC is provided, the parameter value of the first parameter sl-PriorityThreshold-UL-URLLC is regarded as the priority value of the UL signal, and the lowest priority value among the multiple SL signals transmitted on multiple SL carriers is compared with the parameter value of the second parameter sl-PriorityThreshold-UL-URLLC.

[0400] The power reduction method adopts methods 1 and 2 in the above-mentioned scheme 1. When it is necessary to reduce the power of the UL signal corresponding to the first parameter sl-PriorityThreshold-UL-URLLC, the power of the UL signal is reduced until the total transmission power of the terminal on the overlapping time domain resources does not exceed pcmax.

[0401] Case 2: If the first parameter sl-PriorityThreshold-UL-URLLC is not configured, the UL signal has a higher priority than the SL signal, the power of the SL signal is reduced, and method 1 or 2 in solution 1 is used until the total transmit power of the terminal on the overlapping time domain resources does not exceed pcmax.

[0402] Case 3: If the UL signal is not PUSCH and the priority value is 1, or the UL signal is not PUCCH and the priority value is 1, the parameter value of the second parameter sl-PriorityThreshold is regarded as the priority value of the UL signal, and the lowest priority value among multiple SL signals is compared with the second parameter sl-PriorityThreshold.

[0403] The power reduction method adopts method 1 or method 2 in the above-mentioned solution 1. When it is necessary to reduce the power of the signal corresponding to the second parameter sl-PriorityThreshold, the power of the UL signal is reduced until the total transmission power of the terminal on the overlapping time domain resources does not exceed pcmax.

[0404] Using solution 2, the priority comparison between SL and UL signals is specifically performed as follows:

[0405] Case 1: If the first parameter sl-PriorityThreshold-UL-URLLC is provided, the parameter value of the first parameter sl-PriorityThreshold-UL-URLLC is regarded as the priority value of the UL signal, and the priority value of the SL signal transmitted on each sidelink carrier and the parameter value of the first parameter sl-PriorityThreshold-UL-URLLC are prioritized.

[0406] The power reduction method adopts method 1 or method 2 in the above-mentioned scheme 2. When it is necessary to reduce the power of the signal corresponding to the first parameter sl-PriorityThreshold-UL-URLLC, the power of the UL signal is reduced until the total transmission power of the terminal on the overlapping time domain resources does not exceed pcmax.

[0407] Case 2: If the first parameter is not configured, the UL signal has a higher priority than the SL signal. Prioritize multiple SL signals and use method 1 or 2 in solution 2 to reduce their power until the total transmit power of the terminal on the overlapping time domain resources does not exceed pcmax.

[0408] Case 3: If the UL signal is not PUSCH and the priority value is 1, or the UL signal is not PUCCH and the priority value is 1, the parameter value of the second parameter sl-PriorityThreshold is regarded as the priority value of the UL signal, and the priority value of each SL signal and the second parameter sl-PriorityThreshold are prioritized.

[0409] The power reduction method adopts method 1 or method 2 in the above-mentioned solution 2. When it is necessary to reduce the power of the signal corresponding to the second parameter sl-PriorityThreshold, the power of the UL signal is reduced.

[0410] In some embodiments, when multiple SL signals are PSSCHs and the PSSCHs overlap with UL signals in the time domain, the priority comparison rules of the existing SL signals that are PSSCHs and UL signals can be reused, but the PSSCHs transmitted on multiple carriers need to be considered. The following method is used:

[0411] Solution 1: Perform a comparison process between the UL signal and the SL signal once, and use the priority value corresponding to the logical channel with the highest priority among all SL carriers to compare with the second parameter sl-PrioritizationThres.

[0412] Case 1: When the priority value corresponding to the logical channel with the highest priority among all SL carriers is lower than the second parameter, the SL signal has a higher priority than the UL signal, and the power of the UL signal is reduced.

[0413] Case 2: When the UL signal has a higher priority than the SL signal, use method 1 or 2 in the above solution 1 to reduce the power of the SL signal.

[0414] Solution 2: The PSSCH transmitted on each SL carrier needs to perform a comparison process between the UL signal and the SL signal, that is, the lowest priority value of the logical channel on each carrier and the second parameter sl-PrioritizationThres are prioritized, and the parameter value of the second parameter sl-PrioritizationThres is regarded as the priority value of the UL signal. When it is necessary to reduce the power of the UL signal corresponding to the second parameter sl-PrioritizationThres, the power of the UL signal is reduced, and the power reduction uses method 1 or 2 in Solution 2.

[0415] In some embodiments, there is a priority comparison rule between the SL signal and the UL signal of the PSSCH:

[0416] The transmission of a medium access control (MAC) protocol data unit (PDU) takes precedence over uplink transmissions by a MAC entity or other MAC entities if the following conditions are met:

[0417] When the following conditions are met, the SL signal has a higher priority than the UL signal

[0418] 1> If the MAC entity cannot perform this sidelink transmission simultaneously with all uplink transmissions, and

[0419] 1> If the upper layer has no priority for uplink transmission, and

[0420] 1> If the NR uplink MAC PDU does not contain any MAC control element (CE) prioritization, and

[0421] 1> If UL-Priority Thres is configured and the highest priority value of all logical channels of NR uplink transmission is not less than UL-Priority Thres, and

[0422] 1> If SL-Priority Thres is configured and the highest priority value of the logical channel or MAC CE in the MAC PDU is lower than SL-Priority Thres.

[0423] NOTE 2: If the MAC entity cannot perform this sidelink transmission simultaneously with all uplink transmissions at the time of transmission and priority-related information is not available before this sidelink transmission due to processing time constraints, it is up to the UE implementation whether to perform this sidelink transmission.

[0424] When the above conditions are not met, the UL signal has a higher transmission priority than the SL signal.

[0425] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.
