Method and apparatus for measurement and reporting for multi-beam operations

A method comprising:

• transmitting, via a transceiver through a first set of antenna ports corresponding to a first antenna panel, one or more uplink (UL) reference signals (RSs);
• measuring, by a processor 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
• performing, by the processor, 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 transmitting the one or more UL RSs comprises transmitting the one or more RSs via the first set of antenna ports via a repetition mode and measuring comprises measuring the signal qualities 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.

A non-transitory computer readable medium comprising a plurality of instructions that, when executed by a processor of a user equipment (UE), causes the UE to:

• transmit, via a transceiver of the UE 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 plurality of instructions is further configured to cause the UE to transmit the one or more UL RSs via a repetition mode at the first set of antenna ports and measure 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.
