1. A user equipment (UE) comprising:
a transceiver configured to communicate via a multi-beam operation with a base station; and
a processor operably coupled to the transceiver, the processor configured to:
transmit, via the transceiver through a first set of antenna ports corresponding to a first antenna panel, one or more uplink (UL) reference signals (RSs),
measure, via the transceiver using a second set of antenna ports corresponding to a second antenna panel, signal qualities of the one or more UL RSs for a time period, and
perform measurement reporting of the measured signal qualities, wherein the measurement reporting comprises:
a number (L) of smallest or largest reference signal received powers (RSRPs) of the one or more UL RSs, and
corresponding RS indices, where 1≤L<N, and N is a number of the one or more UL RSs transmitted, and
wherein the one or more UL RSs are transmitted via a repetition mode at the first set of antenna ports and measured via a beam-sweep mode at the second set of antenna ports, the repetition mode comprising repeatedly transmitting a same UL RS using same UL resources and the beam-sweep mode comprising using different beams.
