Power Control Method and Terminal

A terminal, wherein the terminal is a first terminal, and the first terminal comprises:

• a processor, a memory, a bus, and a communications interface, wherein
• the processor is configured to obtain parameter information required for power control through the communications interface, wherein the parameter information comprises at least one of a first parameter, a second parameter, and a third parameter;
• and determine, based on the parameter information, uplink transmit power used when uplink transmission is performed on a target beam or a target beam pair;
• wherein
• the first parameter comprises a beam reception gain of a network device and/or a beam sending gain of the first terminal;
• the second parameter comprises a value of interference caused by a second terminal to the first terminal on the target beam, and the second terminal includes one or more terminals other than the first terminal;
• and the third parameter comprises a beam-specific target power and/or a terminal-specific target power;
• and the beam-specific target power is a target power value that is set by the network device for the target beam or the target beam pair;
• and the terminal-specific target power is a target power value that is set by the network device for the first terminal on the target beam or the target beam pair.
