Abstract
Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station; and a processor communicatively coupled to the transceiver. The processor is configured to receive a sounding reference signal (SRS) resource configuration from the base station, wherein the SRS resource configuration indicates at least a first SRS resource and a second SRS resource. The processor is further configured to transmit a first SRS via the first SRS resource to the base station using a first antenna coupled to the transceiver and transmit a second SRS via the second SRS resource to the base station using a second antenna coupled to the transceiver. The processor is further configured to receive an SRS resource indicator (SRI) from the base station based on at least one of the transmission of the first SRS or the second SRS; select the first antenna based on the SRI indicating the first SRS resource; and transmit uplink data to the base station using the first antenna.
