Classification: CPC H | IPC H

Claim 0:
1. A user equipment (UE) comprising:
a transceiver configured to:
receive configuration information including a set of transmission configuration indicator (TCI) states, and
receive a medium access control-control element (MAC-CE) indicating activation of M TCI states from the set of TCI states, where M is a positive integer; and

a processor operably coupled to the transceiver, the processor configured to:
identify a medium for receiving an indication indicating a TCI state update, wherein the medium is the MAC-CE or a downlink control information (DCI), and the TCI state update is from the M activated TCI states,
determine a beam based on the TCI state update, and
apply the beam for a reception of both downlink (DL) control and data channels,

wherein:
the identification of the medium is based on a value of M,
a TCI state refers to at least one source reference signal (RS) with a corresponding quasi co-location (QCL) type,
the QCL type is a type of a QCL property associated with the at least one source RS, and
the beam refers to the QCL type being set to a spatial property used to receive or transmit the at least one source RS included in the TCI state update.
