1. A equipment (UE) for beam management, the UE comprising:
at least one processor; and
at least one non-transitory computer-readable medium storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:
receive a downlink control information (DCI) format in a first band width part (BWP) based on a first quasi co-located (QCL) assumption specific to the first BWP, the DCI format scheduling a reception of a physical downlink shared channel (PDSCH) in a second BWP;
receive a radio resource control (RRC) configuration that includes a plurality of candidate transmission configuration indication (TCI) states associated with a serving cell in which the reception of the PDSCH is scheduled;
receive a medium access control (MAC) control element (CE) that indicates a subset of the plurality of candidate TCI states for activation in the second BWP;
determine a second QCL assumption specific to the second BWP based on one candidate TCI state in the subset of the plurality of candidate TCI states;
initiate a random access procedure and transmit an acknowledgement in the second BWP; and
receive, after the random access procedure is initiated, the PDSCH in the second BWP based on the second QCL assumption.
