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.
