FIELD: electrical communication engineering.
SUBSTANCE: invention relates to uplink power control. To this end, the terminal device obtains information for uplink power control transmitted by the network device; determining by the terminal device, according to the uplink power control information, the target power control parameter corresponding to the target transmission mode, where the target transmission mode is an uplink multiple access target mode, or the target transmission mode is an uplink target beam, or the target transmission mode is a target uplink coding scheme, or the target transmission mode is a target transmission scheduling scheme; and determining, by the terminal device, according to the target power control parameter, the target transmission power for transmitting the uplink target signal using the target transmission mode.
EFFECT: enabling flexible adjustment of uplink transmission power to meet requirements of different transmission modes, and the method and device are suitable for a communication system supporting multiple transmission modes.
