Abstract:
A user equipment (UE) is disclosed including a receiver that receives Sounding Reference Symbol (SRS) configuration information that indicates a first resource used for transmission of a predetermined reference signal from a base station (BS). The UE includes a transmitter that transmits an SRS using a second resource that is the first resource. The UE further includes a processor that determines a precoder applied to the SRS based on the predetermined reference signal. The transmitter transmits the SRS precoded using the determined precoder. The predetermined reference signal is a Channel State Information Reference Signal (CSI-RS), an SRS, or a Synchronization Signal Block (SSB)/Physical Broadcast Channel (PBCH).
