Abstract
A method of a user equipment (UE) for beam management in a wireless communication system is provided. The method comprises receiving, from a base station (BS), a radio resource control (RRC) signaling and a medium access control channel element (MAC CE) signaling including a beam indicator over a downlink channel for the beam management, identifying the beam indicator based on the RRC signaling and the MAC CE signaling, and determining the beam indicator for a physical downlink control channel (PDCCH), a common physical downlink shared channel (PDSCH), and a fallback unicast PDSCH.

A user equipment (UE) for beam management in a wireless communication system, the UE comprising:
- a transceiver configured to receive, from a base station (BS), a radio resource control (RRC) signaling and a medium access control channel element (MAC CE) signaling including a beam indicator over a downlink channel for the beam management;
- and
- a processor configured to:
- identify the beam indicator based on the RRC signaling and the MAC CE signaling;
- and
- determine the beam indicator for a physical downlink control channel (PDCCH), a common physical downlink shared channel (PDSCH), and a fallback unicast PDSCH.
A base station (BS) for beam management in a wireless communication system, the BS comprising:
- a processor configured to:
- determine a beam indicator for a physical downlink control channel (PDCCH), a common physical downlink shared channel (PDSCH), and a fallback unicast PDSCH;
- and
- configure the beam indicator based on a radio resource control (RRC) signaling and a medium access control channel element (MAC CE) signaling;
- and
- a transceiver configured to transmit, to a user equipment (UE), the RRC signaling and the MAC CE signaling including the beam indicator over a downlink channel for the beam management.
