Abstract
A terminal, as disclosed, includes: a processor that controls a beam used for transmission of a sounding reference signal (SRS) in accordance with presence or absence of a configuration of a spatial domain parameter for the SRS; and a transmitter that transmits the SRS using the beam. The processor respectively uses different beams for a plurality of resources for the SRS when the spatial domain parameter is not configured. Or the processor uses a fixed beam for a plurality of resources for the SRS when the spatial domain parameter is not configured. In other aspects, a communication method and a system are also disclosed.
