receive, from a Base Station (BS), a Radio Resource Control (RRC) message comprising an NES configuration; and
determine whether to apply a cell Discontinuous Transmission (DTX) operation, a cell Discontinuous Reception (DRX) operation, or both the cell DTX operation and the cell DRX operation based on the NES configuration.
9 . The UE of claim 8 , wherein:
the NES configuration is included in a cell configuration carried by the RRC message, and
the cell DTX operation, the cell DRX operation, or both the cell DTX operation and the cell DRX operation is/are applied to a cell associated with the cell configuration.
10 . The UE of claim 8 , wherein:
the UE is served by a plurality of cells, and
the cell DTX operation, the cell DRX operation, or both the cell DTX operation and the cell DRX operation is/are applied to one of the plurality of cells serving the UE.

the NES configuration comprises a set of common parameters applicable to both the cell DTX operation and the cell DRX operation.
12 . The UE of claim 11 , wherein:
the set of common parameters comprises an on-duration timer, a cycle, a start offset, and a slot offset.
13 . The UE of claim 11 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:
determine a first on-duration period for the cell DTX operation and a second on-duration period for the cell DRX operation based on the set of common parameters.
14 . The UE of claim 8 , wherein:
the NES configuration comprises a parameter for indicating whether to apply the cell DTX operation, the cell DRX operation, or both the cell DTX operation and the cell DRX operation.
