1. A processor of a base station configured to perform operations comprising:
generating, for transmission to a user equipment (UE), a CSI-ReportConfig information element (IE), wherein the CSI-ReportConfig IE comprises an indication of group based beam reporting;
generating, for transmission to the UE, a CSI-ResourceConfig IE, wherein the CSI-ResourceConfig IE comprises a plurality of resource sets for a plurality of transmission and reception points (TRPs), each resource set comprising a plurality of beamformed reference signals (RSS), and wherein the UE is configured to select a first resource set and a second resource set from the plurality of resource sets based on the indication of group based beam reporting in the CSI-ReportConfig IE; and
receiving a CSI measurement report from the UE, wherein the CSI measurement report is based on the first and the second resource set.
