Abstract

Certain aspects of the present disclosure provide techniques for signaling quasi-coloration (QCL) information for demodulation reference signals (DM-RS) associated with multiple transmission-reception points (multi-TRP). An example method generally includes generating quasi-colocation (QCL) information indicating a first QCL assumption for a first group of demodulation reference signal (DM-RS) ports and a second QCL assumption for a second group of DM-RS ports; and transmitting the QCL information to at least one user equipment (UE) for use in processing one or more transmission associated with at least one of the first group of DM-RS ports and the second group of DM-RS ports.
