Default beam selection based on a subset of coresets

An apparatus for wireless communication at a User Equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a base station, an indication corresponding to a Channel Occupancy Time (COT), wherein the indication is for at least one of a set of Control Resource Sets (CORESETs), a set of Quasi co-location (QCL) assumptions, a set of uplink resources, or a set of spatial relations for determining a default beam;
• determine the default beam from the base station for use during the COT based on the indication;
• and
• transmit or receive a transmission using the default beam.
