1. A method, comprising:
receiving a configuration with first resources for physical downlink control channel (PDCCH) monitoring and configuration of an associated control resource set (CORESET), wherein the first resources occupy a subset of a plurality of OFDM symbols within a slot;
receiving a message scheduling a physical downlink shared channel (PDSCH) demodulation reference signal (DM-RS) in the slot, wherein a first front-loaded DMRS symbol of the PDSCH DM-RS is to collide with the first resources according to a schedule; and
determining to receive the first front-loaded DMRS symbol of the PDSCH DM-RS starting at a shifted symbol location based on the schedule, wherein the shifted symbol location is immediately after the associated CORESET.
