User equipments, base stations, and methods for srs transmission and transmission power control
A user equipment (UE) is described. The UE includes reception circuitry configured to receive information of a first parameter, a second parameter, and a third parameter for a sounding reference signal (SRS) bandwidth in an uplink bandwidth part (UL BWP). The UE also includes transmission circuitry configured to transmit the SRS. In a case that the first parameter and the second parameter are received, a transmission power of the SRS is determined based on the first parameter and the second parameter. In a case that the first parameter, the second parameter, and the third parameter are received, the transmission power of the SRS is determined based on the first parameter, the second parameter, and the third parameter.
