Control resource set determination for multiple transmission-reception point configurations

A method for wireless communication at a base station, comprising:

• transmitting, to a user equipment (UE) operating in a multi-transmission-reception point operation mode, control information on a first set of control resource sets using a first transmission-reception point and control information on a second set of control resource sets using a second transmission-reception point;
• identifying a subset of the first set of control resource sets on which to transmit control information to the UE using the first transmission-reception point when the UE is in a single-transmission-reception point operation mode, wherein the single-transmission-reception point operation mode is associated with communicating with the UE using the first transmission-reception point, and wherein a number of control resource sets in the first set of control resource sets exceeds a control resource set limit for the single-transmission-reception point operation mode;
• transmitting, to the UE, an indication for the UE to transition from the multi-transmission-reception point operation mode to the single-transmission-reception point operation mode;
• and
• transmitting, to the UE, control information on the subset of the first set of control resource sets after the UE transitions to the single-transmission-reception point operation mode.

An apparatus for wireless communication at a user equipment (UE), 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:
• monitor, in a multi-transmission-reception point operation mode, a first set of control resource sets for control information from a first transmission-reception point and a second set of control resource sets for control information from a second transmission-reception point;
• receive an indication to transition from the multi-transmission-reception point operation mode to a single-transmission-reception point operation mode, wherein the single-transmission-reception point operation mode is associated with communicating with the first transmission-reception point, and wherein a number of control resource sets in the first set of control resource sets exceeds a control resource set limit for the single-transmission-reception point operation mode;
• identify a subset of the first set of control resource sets to monitor for control information from the first transmission-reception point in the single-transmission-reception point operation mode based at least in part on the indication;
• and
• monitor the subset of the first set of control resource sets for control information from the first transmission-reception point in the single-transmission-reception point operation mode.
