Abstract:
In a multi-BPL scenario, some form of beam-related indication is desirable to provide assistance to the UE in setting its Rx spatial filtering configuration to receive PDSCH. The assistance to the UE is in the form of a certain indicator indicating a spatial QCL assumption between PDSCH DMRS antenna port(s) and DL RS (e.g., CSI-RS) antenna port(s), such as a preferred CSI-RS resource that was measured and reported previously.
