Abstract:
Methods, systems, and devices for wireless communications are described for determination of sounding reference signal (SRS) parameters when multiple SRS resource sets are configured for a same SRS transmission resource. A user equipment (UE) may select one SRS resource set for a SRS transmission based on a prioritization of different SRS resource sets. In some cases, different SRS resource sets may be associated with different SRS usage parameters that indicate a use case for the SRS, and the UE may transmit a joint SRS for two or more SRS resource sets for predetermined combinations of SRS usage parameters. A base station that receives the SRS transmission may measure one or more channel parameters of the SRS and determine one or more settings for subsequent communications with the UE.
