Abstract
The UE includes higher layer circuitry configured to receive information including more than one transmission configuration indication (TCI) states. The UE also includes medium access control (MAC) circuitry configured to receive a first MAC control element (CE) and a second MAC CE. The UE further includes reception circuitry configured to receive first downlink control information (DCI) on a physical downlink control channel (PDCCH), and second DCI on a PDCCH. The first MAC CE selects one of more TCI states from the more than one TCI states and maps the selected one or more TCI states to the codepoints of a TCI field in the second DCI. The second MAC CE selects one of more TCI states from the more than one TCI states and maps the selected one or more TCI states to the codepoints of the TCI field in the second DCI.
