Abstract

Method and apparatus for multi-carrier/multi-cell discontinuous reception (DRX)/discontinuous transmission (DTX) operations, autonomous deactivation of the secondary carrier(s)/cell(s), and explicit activation/deactivation of DRX/DTX and secondary carriers/cells are disclosed. A user equipment (UE) may configure at least one state variable for controlling DRX and/or DTX on a plurality of cells and perform an DRX and/or DTX operation on a subset of cells based on a state variable associated with the subset of cells on a cell group basis. The UE may activate or deactivate DRX and/or DTX based on an order from a network for all cells, a group of cells, or an individual cell. The UE may deactivate the secondary cells autonomously based on activity on the cell(s).
