Control resource set precoding indication

A method of wireless communication performed by a base station, comprising:

• determining, for a control resource set (CORESET), a precoder granularity unit over which a same precoding is used for resources of the CORESET,
• wherein the precoder granularity unit is greater than a resource element group (REG) bundle of the CORESET and less than contiguous resource blocks of the CORESET;
• and
• transmitting, to a user equipment (UE), a configuration that indicates the precoder granularity unit, to enable the UE to monitor for one or more physical downlink control channel (PDCCH) candidates according to the configuration.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a configuration for a control resource set (CORESET) that indicates a precoder granularity unit over which a same precoding is used for resources of the CORESET,
• wherein the precoder granularity unit is greater than a resource element group (REG) bundle of the CORESET and less than contiguous resource blocks of the CORESET;
• and
• monitor for one or more physical downlink control channel (PDCCH) candidates according to the configuration.
