Abstract
Methods and apparatuses for group-based beam reporting with L1-RSRP measurement for multi-TRP DL transmission are disclosed. In one embodiment, a method comprises receiving a CSI reporting setting linked to two Resource Settings for channel measurement for group based beam reporting, and transmitting a CSI report corresponding to the CSI reporting setting, wherein the CSI report includes two or more CRIs or SSBRIs and their corresponding received powers.
Claims18
A method performed by a base station, the method comprising:
- receiving a channel state information (CSI) report corresponding to a CSI reporting setting for a group based beam report, wherein the CSI report includes N pairs of two CSI-RS resource indicators (CRIs) or synchronization signal block (SSB) resource indicators (SSBRIs) and their corresponding received powers, N is configured by radio resource control (RRC) signaling and is a positive integer, and the CSI-RS or SSB resources indicated by CRIs or SSBRIs in each pair are received concurrently by a user equipment (UE));
- wherein:
- the received power with the largest value among received powers based on the CSI-RS or SSBRI resources in both a first Resource Setting and a second Resource Setting is included in the CSI report as RSRP, and the CSI report includes an extra one-bit indication indicating the RSRP is based on a CSI-RS or SSBRI resource in the first Resource Setting or in the second Resource Setting, and
- other received power(s) are included in the CSI report as differential RSRP(s).

A base station, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- receive a channel state information (CSI) report corresponding to a CSI reporting setting for a group based beam report, wherein the CSI report includes N pairs of two CSI-RS resource indicators (CRIs) or synchronization signal block (SSB) resource indicators (SSBRIs) and their corresponding received powers, N is configured by radio resource control (RRC) signaling and is a positive integer, and the CSI-RS or SSB resources indicated by CRIs or SSBRIs in each pair are received concurrently by a user equipment (UE));
- wherein:
- the received power with the largest value among received powers based on the CSI-RS or SSBRI resources in both a first Resource Setting and a second Resource Setting is included in the CSI report as RSRP, and the CSI report includes an extra one-bit indication indicating the RSRP is based on a CSI-RS or SSBRI resource in the first Resource Setting or in the second Resource Setting, and
- other received power(s) are included in the CSI report as differential RSRP(s).
