Claim 0:
1. A method of wireless communication by a base station (BS), comprising:
determining channel state information reference signal (CSI-RS) port groups associated with one or more non-zero power (NZP) CSI-RS resources for channel measurement (CM) or interference measurement (IM);
transmitting an indication of the CSI-RS port groups to at least one UE;
generating quasi-colocation (QCL) information indicating QCL assumptions for the CSI-RS port groups; and
transmitting the QCL information to the at least one UE comprising transmitting a plurality of transmission configuration indicator (TCI) states for the CSI-RS port groups of the one or more NZP CSI-RS resources, each of the plurality of TCI states comprises a different QCL configuration associated with one of the CSI-RS port groups such that a first TCI state of the plurality of TCI states comprises a first QCL configuration for a first CSI-RS port group and a second TCI state of the plurality of TCI states comprises a second QCL configuration for a second CSI-RS port group, wherein the first QCL configuration is different from the second QCL configuration.
