1. A power control method, wherein the method is applied to a terminal, and the terminal has a capability of supporting a configuration with a plurality of control resource set (CORESET) pool indexes, the terminal is configured with a plurality of CORESET pool indexes, or the terminal has a capability of supporting a configuration with a plurality of CORESET pool indexes and is configured with the plurality of CORESET pool indexes, and the method comprises:
receiving a first physical downlink control channel (PDCCH) sent by a network device, wherein the first PDCCH carries a power offset corresponding to a physical uplink shared channel (PUSCH);
determining an accumulation result based on a power control process corresponding to the network device, wherein the power control process is used for accumulating power offsets carried by PDCCHs from the network device, and determining a transmit power for the PUSCH based on the accumulation result; and
sending the PUSCH to the network device at the transmit power,
wherein before the determining the transmit power based on the power control process corresponding to the network device, the method further comprises:
receiving a second PDCCH sent by the network device, wherein the second PDCCH carries indication information of the power control process, the indication information indicates that there is a correspondence between the power control process and a CORESET pool corresponding to the second PDCCH, and the second PDCCH and the first PDCCH correspond to the same CORESET pool.
