FIELD: wireless communication.
SUBSTANCE: method for controlling uplink power contains: determining, according to a number of bandwidth parts (hereinafter – BWP) for sending an uplink signal or a number of closed-loop power control processes related to the uplink signal, a certain number of bits of the area of a transmission power control (hereinafter – TPC) command of a terminal device in downlink control information (DCI); and determining, according to the TPC command in the TPC command area, the closed-loop power adjustment coefficient of at least one BWP for sending the uplink signal or at least one closed-loop power control process related to the uplink signal.
EFFECT: aim of the invention consists in obtaining the corresponding TPC command of each power control process in the closed loop in each BWP.
