Patent attributes
Embodiments of this application describe a power control method and a device, and relate to the field of communications technologies. A network device operating in a full-duplex mode can correctly receive data during data sending. The method may include receiving, by user equipment (UE), power control parameter information of an uplink transmit power from a network device, where the power control parameter information includes first power control parameter information and second power control parameter information, the first power control parameter information is used to calculate an uplink transmit power for data transmission on a non-full-duplex resource, and the second power control parameter information includes a parameter for calculating an uplink transmit power for data transmission on a full-duplex resource. The method may also include determining, by the UE, an uplink transmit power based on the power control parameter information and a resource type used for uplink transmission, where the resource type includes a full-duplex resource and a non-full-duplex resource.
