Abstract:
Apparatuses, systems, and methods for SRS antenna switching. A UE may transmit, to a base station, a capability message indicating an antenna configuration associated with SRS antenna switching e.g., via as RRC signaling. The capability message may indicate at least one of (and/or one or more of) a one transmit point (1T) and six receive point (6R) SRS resource set configuration, a 1T8R SRS resource set configuration, a 2T6R SRS resource set configuration, a 2T8R SRS resource set configuration, and/or a 4T8R SRS resource set configuration. The UE may receive, from the base station, a configuration message, e.g., via RRC signaling. The configuration message may indicate an SRS antenna switching configuration based, at least in part, on the capability message. The UE may transmit, to the base station, one or more SRSs, e.g., according to the SRS antenna switching configuration.
