8. A terminal device, comprising a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, the steps of the power control method are implemented, the method comprises:
receiving, by a terminal, configuration information from a network device, wherein the configuration information is used to indicate target spatial relation information of target uplink data; and
determining, by the terminal, transmit power of the target uplink data based on the target spatial relation information; wherein
the target spatial relation information comprises at least one of the following: M power control parameters, a target power control parameter corresponding to the target spatial relation information, and information used to indicate the target power control parameter, wherein M is a positive integer; and
the target uplink data comprises a sounding reference signal SRS or a physical uplink shared channel PUSCH;
wherein if no path loss calculation reference reference signal is configured for the target power control parameter, a reference signal quasi co-located with a control resource set is used as a path loss calculation reference reference signal.
