Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report indicating a mapping between antenna panels and reference signal beam indications. The UE may transmit the report and apply the mapping to the antenna panels for reference signals. Numerous other aspects are provided.
Claims20
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive a configuration associated with sounding reference signals (SRSs), wherein:
- the SRSs are associated with one or more beam indications,
- the one or more beam indications correspond to spatial relation information and to a downlink reference signal that is a source reference signal, and
- the one or more beam indications are associated with a maximum quantity of antenna ports for uplink communications;
- and
- communicate with a network entity based at least in part on the one or more beam indications.
