Classification: CPC H | IPC H

Claim 13:
14. A user equipment (UE) for wireless communication, comprising:
memory;
one or more processors coupled to the memory; and
instructions stored in the memory and operable, when executed by the one or more processors, to cause the UE to:
receive a configuration that indicates a density of demodulation reference signal (DMRS) resource elements and a set of locations of the DMRS resource elements in one or more resource element groups associated with a physical downlink control channel (PDCCH);
receive an indication of a selected DMRS density and location option from a plurality of DMRS density and location options, the indication further being of a change to at least one of the density of the DMRS resource elements or the set of locations of the DMRS resource elements, resulting in at least one of a modified density of the DMRS resource elements or a modified set of locations of the DMRS resource elements, wherein the modified density of the DMRS resource elements and the modified set of locations of the DMRS resource elements correspond to the selected DMRS density and location option; and
monitor for downlink control information in a search space associated with the PDCCH based at least in part on the at least one of the modified density of the DMRS resource elements or the modified set of locations of the DMRS resource elements.
