Original Abstract Submitted

embodiments are disclosed for capability reporting for antenna switching, as, sound reference signals, srs. a user equipment (ue) can transmit a capability report for as srs that includes a plurality of receive antenna (e.g., six or eight receive antenna), and receive srs instructions based on the capability report. the ue can transmit a first temporary capability reduction for a duration, and transmit a first srs according to the first temporary capability reduction and the srs instructions, while maintaining phase continuity. to maintain phase continuity, the ue can calibrate one or more srs ports participating in the as srs to transmit with substantially a same transmit power. the ue can determine that a second srs overlaps an other transmission in a time domain, determine that the other transmission has an absolute priority over the second srs, and transmit the other transmission but not the second srs.
