Shared channel rate matching with wideband demodulation reference signal for a control channel

An apparatus for wireless communications, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive downlink control information (DCI) within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and comprising a plurality of disjoint segments of resource blocks (RBs), wherein the DCI is located at least partially within a first segment of the plurality of disjoint segments and a second segment of the plurality of disjoint segments is exclusive of the DCI, and wherein the DCI comprises a grant of a set of resources for a downlink shared channel that overlaps with the CORESET;
• determine a rate matching operation for the wideband DMRS for the downlink shared channel for portions of the set of resources that overlap with the second segment of the plurality of disjoint segments;
• and
• receive the downlink shared channel on the set of resources according to the determined rate matching operation.
