Methods and apparatuses for triggering adaptation for wireless communication system
Apparatuses and methods for triggering cell-specific or UE-group-specific adaptation. A method of a user equipment (UE) in a wireless communication system includes receiving, from a base station (BS), a set of higher layer parameters and determining a set of adaptation aspects based on the set of higher layer parameters. The method further includes determining a set of configurations for receiving a physical downlink control channel (PDCCH) and receiving the PDCCH based on the set of configurations. The PDCCH carries adaptation indicators including a set of code-points that corresponds values for the set of adaptation aspects, respectively. The method further includes applying the values for the set of adaptation aspects based on the set of code-points included in the adaptation indicators.

receiving, from a base station, configuration information for a cell operation including a cell discontinuous reception (DRX) operation;
receiving, from the base station, downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a specific radio network temporary identifier (RNTI) associated with the cell operation, the DCI including one or more indicators indicating whether to activate the cell operation for one or more serving cells; and
identifying that the cell operation is activated or deactivated based on the one or more indicators indicating activation or deactivation of the cell operation.
8 . The method of claim 7 , further comprising monitoring a physical downlink control channel (PDCCH) for detection of the DCI including the one or more indicators indicating whether to activate the cell operation for the one or more serving cells on a common search space.

the cell operation further comprises an operation of which the base station does not transmit data in the one or more serving cells during a non-active duration, and
the UE does not monitor a PDCCH during the non-active duration in case that the UE is configured with the cell operation and the cell operation is activated for the one or more serving cells.
11 . The method of claim 7 , wherein the cell operation is configured with a UE group.
12 . The method of claim 7 , wherein identifying that the cell operation is activated or deactivated comprises identifying that the cell operation is activated or deactivated based on each bit value of the one or more indicators.
13 . A base station in a wireless communication system supporting network energy saving, the base station comprising:
a transceiver; and
a processor configured to:
