1. A method of wireless communication at a user equipment (UE), comprising:
transmitting an indication of a capability to determine a default beam for physical downlink shared channel (PDSCH) that is independent of a beam for a control resource set (CORESET) for a physical downlink control channel (PDCCH);
determining the default beam for the PDSCH that is independent of the beam for the CORESET for the PDCCH, based on information received in a medium access control-control element (MAC-CE), a radio resource control (RRC) message, a downlink control information (DCI), or a message activating at least one transmission configuration indication (TCI) state for the PDSCH; and
using the default beam based on the information received in the MAC-CE, the RRC message, the DCI, or the message activating the at least one TCI state to receive the PDSCH from a base station in response to a determination that a scheduling offset between the PDSCH and a scheduling DCI that schedules the PDSCH is less than a threshold.
