Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A base station (BS) comprising:
a processor configured to:
generate configuration information including a set of transmission configuration indicator (TCI) states, and
generate 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 transceiver operably coupled to the processor, the transceiver configured to:
transmit the configuration information,
transmit, via a medium, an indication indicating a TCI state update, the TCI state update indicating a beam from the M activated TCI states, wherein the medium is the MAC-CE or a downlink control information (DCI) identified based on a value of M, and
transmit downlink (DL) control and data channels for reception via the indicated beam,

wherein:
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.
