1. A power control apparatus, comprising:a processor; and
a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
generate a correspondence between a power control command and a serving cell of a terminal device or a serving cell group of the terminal device
send the generated correspondence, and send multiple power control commands in one serving cell of the terminal device according to the correspondence generated by the power control apparatus, after generating the correspondence, wherein a power control command in the multiple power control commands instructs the terminal device to adjust transmit power of the terminal device in the serving cell or the serving cell group;
generate downlink control information, wherein the downlink control information comprises:
the multiple power control commands and one of identifier information of serving cells corresponding to the multiple power control commands or identifier information of serving cell groups corresponding to the multiple power control commands; or
the multiple power control commands and identifier information of one serving cell or of one serving cell group; and
send, in one serving cell of the terminal device, the downlink control information generated by the processor, after generating the downlink control information.
