The present invention relates to a method and a terminal for a terminal to transmit an uplink signal, the method comprising: receiving a serving base station for determining a transmit power indication; selecting a formula from a plurality of uplink power control of uplink power control formulas according to the instruction; using uplink power control formula selected transmit power of an uplink signal obtained; uplink transmit power using the transmit signal. By selecting a uplink power control formula, such that the terminal can not only select the appropriate mode according to the received uplink power control formula determines the transmission signal, to meet the power received at different manner from the current demand controlling the plurality of uplink power control formulas according to an instruction of the serving base station, and the configuration parameters for the different aperiodic SRS can be used a corresponding uplink power control formula, determine the appropriate transmit power to transmit an uplink signal to improve the signal transmission performance and flexibility of the uplink transmit power of the terminal control.
