The invention relates to an uplink signal transmitting method for a terminal, and the terminal. The method comprises the following steps of: receiving indication used for determining the transmitting power sent by a service base station; according to the indication, selecting one uplink power control formula from multiple uplink power control formulae; obtaining the transmitting power of an uplink signal by utilizing the selected uplink power control formula; and transmitting the uplink signal by utilizing the transmitting power. One uplink power control formula is selected from multiple uplink power control formulae according to the indication of the service base station; therefore, the terminal can determine a transmitting signal by selecting the corresponding uplink power control formula according to a receiving manner, and satisfy power control requirements in current different receiving manners; furthermore, for different configuration parameters of aperiodic SRS, the terminal also can determine the proper transmitting power to transmit the uplink signal by using the corresponding uplink power control formula; and thus, the uplink transmitting power control flexibility and signal transmitting performance of the terminal can be improved.
