Partial/full overlapping of multiple PDSCHs for non-ideal backhaul and associated rate matching of DMRS ports

Abstract:

Certain aspects of the present disclosure provide techniques for rate matching PDSCH transmissions in multi-TRP scenarios. In some cases, if first and second TRPs have little or no coordination, each TRP may take care to avoid transmitting on DMRS resources of the other TRP. In some cases, each TRP may be assigned a different subset of DMRS ports of a port group.
