Abstract:
Aspects presented herein may enable a base station to map one or more DMRSs to one or more REs of a slot based on the locations of one or more CRSs in the slot and/or based on whether at least one DMRS overlaps with at least one CRS. In one aspect, the base station maps PDCCH DMRS of a first RAT to a CORESET based on whether CRS of a second RAT overlaps at least partially with the CORESET. The base station transmits the PDCCH DMRS mapped to the CORESET.
