Abstract
A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

Claim
A wireless transmit/receive unit (WTRU), comprising:
a memory; and
a processor configured to:
receive a configuration message, wherein the configuration message indicates a group associated with group-based reporting that uses a short cycle, and wherein the group-based reporting is associated with a reduced level of reporting compared to a level of reporting associated with beam-based reporting that uses a long cycle;
send a group-based report in accordance with the short cycle, wherein the group-based report is based on measurement information associated with a representative beam and reference signal received power (RSRP) information, and wherein the representative beam is one of a plurality of beams in the indicated group; and
send a beam-based report in accordance with the long cycle, wherein the beam-based report is based on measurement information for individual beams.
2. The WTRU of claim 1, wherein the group-based report comprises a lesser amount of measurement information than the beam-based report.
3. The WTRU of claim 1, wherein the representative beam is a beam that has a maximum measurement value compared to other beams in the indicated group.
4. The WTRU of claim 1, wherein the processor is further configured to cause the WTRU to take measurements of the individual beams, wherein the individual beams comprise a first beam and a second beam, and the beam-based report comprises a differential RSRP between the first beam and the second beam.
5. A method comprising:
receiving a configuration message, wherein the configuration message indicates a group associated with group-based reporting that uses a short cycle, and wherein the group-based reporting is associated with a reduced level of reporting compared to a level of reporting associated with beam-based reporting that uses a long cycle;
sending a group-based report in accordance with the short cycle, wherein the group-based report is based on measurement information associated with a representative beam and reference signal received power (RSRP) information, and wherein the representative beam is one of a plurality of beams in the indicated group; and
sending a beam-based report in accordance with the long cycle, wherein the beam-based report is based on measurement information for individual beams.
6. The method of claim 5, wherein the group-based report comprises a lesser amount of measurement information than the beam-based report.
7. The method of claim 5, wherein the representative beam is a beam that has a maximum measurement value compared to other beams in the indicated group.
8. The method of claim 5, further comprising taking measurements of the individual beams, wherein the individual beams comprise a first beam and a second beam, and the beam-based report comprises a differential RSRP between the first beam and the second beam.
9. A wireless transmit/receive unit (WTRU), comprising:
a memory; and
a processor configured to:
receive configuration information;
determine at least one beam for beam measurement and beam reporting based on the configuration information, wherein, on a condition that the configuration information indicates a beam for the beam reporting, the processor is configured to report the beam measurement for the beam a first number of times over a duration in accordance with the configuration information, and on a condition that the configuration information indicates a plurality of beams for the beam reporting, the processor is configured to report the beam measurement for the plurality of beams a second number of times over the duration in accordance with the configuration information, wherein the first number of times is different from the second number of times; and
send an uplink transmission to report the beam measurement for the at least one beam.
