[0337] In some embodiments, the above method may include the method described in the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.

[0338] The present disclosure also provides a power control method, as described below:

[0339] Method 1: Ensure that the transmission power of each resource element (RE) is the same.

[0340] In some embodiments, indication information from a network is received to determine which SRSs or SRS sets are sounding reference signals (SRSs) or SRS sets that need to be aggregated.

[0341] Optionally, indication mode 1: an identifier (link ID) is configured for each SRS or SRS set, and SRSs with the same link ID are SRSs that need to be aggregated.

[0342] Optionally, indication mode 2: configuring different sounding reference signal lists (SRS-pos set) for positioning, where the SRS or SRS set in the list is the SRS or SRS set that needs to be aggregated.

[0343] In some embodiments, the transmit power of the SRS or SRS set that needs to be aggregated is determined: the respective power control parameters are configured according to each SRS or SRS set, and the transmit power of the SRS or SRS set under each component carrier (CC) is determined according to the existing formula, assuming that the transmit powers of CC1, CC2, and CC3 determined according to their respective power control parameters are P1, P2, and P3.

[0344] Optionally, if (P1+P2+P3)≤maximum transmit power (Pcmax), the total transmit power is P1+P2+P3, and the transmit power of each subcarrier of the aggregated SRS is P RE=(P1+P2+P3) / sum(REs in all CCs). To ensure the transmit power of each subcarrier, when the SRS on each CC is mapped to the physical resource, the weighting coefficient β of each RE symbol needs to be the same, and the value of β needs to ensure that the total transmit power is (P1+P2+P3). In practice, the transmit power on CC1 is Pcc1=P RE ×Sum(REs in CC1). The actual transmit power on other CCs is similar.

[0345] Optionally, if (P1+P2+P3)>Pcmax, the total transmission power is Pcmax. Then the transmission power of each subcarrier of the aggregated SRS is P RE =(Pcmax) / sum(REs in all CCs). When the SRS or SRS set on each CC is mapped to physical resources, the weighting coefficient β of each RE symbol must be the same and the total transmit power must be Pcmax. The actual transmit power of the SRS or SRS set on each CC is the transmit power of each subcarrier multiplied by the number of REs.

[0346] Method 2: Not considering the power of each RE is the same

[0347] In some embodiments, indication information from the network is received to determine which SRSs or SRS sets need to be aggregated.

[0348] Optionally, the indication method is the same as in method 1

[0349] In some embodiments, the transmit power of an SRS or SRS set to be aggregated is determined by configuring the power control parameters for each SRS or SRS set to determine the transmit power of the SRS or SRS set for each CC. Assume that the transmit powers of CC1, CC2, and CC3 determined based on their respective power control parameters are P1, P2, and P3.

[0350] Optionally, if (P1+P2+P3)>Pcmax.

[0351] Optionally, the transmission of the SRS or SRS set in the component carrier with better channel quality is guaranteed, and power backoff is performed on the SRS or SRS set of other CCs.

[0352] Optionally, Pcmax is divided equally among the CCs, or divided proportionally. The proportions can be determined based on the expected P1, P2, and P3. For example, the actual transmit power of CC1 is Pcmax*P1 / (P1+P2+P3).

[0353] In the embodiments of the present disclosure, each step can be implemented as an independent embodiment. Part or all of the steps and their optional implementations can be arbitrarily combined with part or all of the steps in other embodiments, or with the optional implementations of other embodiments.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
