Claim 12:
13. A method for operating a user equipment (UE), the method comprising:
receiving configuration information including a set of transmission configuration indicator (TCI) states;
receiving 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;
identifying 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;
determining a beam based on the TCI state update; and
applying the beam for a reception of both downlink (DL) control and data channels,
wherein:
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.
