Default beam selection based on a subset of coresets

Abstract

In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

What is claimed is: 
     
         1 . A method of wireless communication at a User Equipment (UE), comprising:
 receiving, 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;   determining the default beam from the base station for use during the COT based on the indication; and   transmitting or receiving a transmission using the default beam.
