Patent attributes
A method for a terminal to transmit an uplink signal is provided. The method includes: receiving an instruction sent by a serving base station and used for determining transmit power; selecting an uplink power control formula from a plurality of uplink power control formulas according to the instruction; obtaining transmit power of an uplink signal by using the selected uplink power control formula; and transmitting an uplink signal by using the transmit power. According to the application, a terminal is not only capable of selecting, according to a receiving manner, an associated uplink power control formula to determine a transmit signal, but also capable of using the uplink power control formula for a different configuration parameter of a non-periodical SRS to determine suitable transmit power to transmit an uplink signal.
