METHOD AND APPARATUS FOR PERFORMING DISCONTINUOUS RECEPTION AND/OR DISCONTINUOUS TRANSMISSION FOR A MULTI-CARRIER/MULTI-CELL OPERATION
First Claim
1. A method of performing discontinuous reception (DRX) and/or discontinuous transmission (DTX) for a multi-cell operation, the method comprising:
- a user equipment (UE) configuring at least one state variable for controlling DRX and/or DTX on a plurality of cells; and
the UE performing 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.

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).

6. A method for activating and deactivating secondary cells, the method comprising:
-
receiving a high speed shared control channel (HS-SCCH) order for activating and/or deactivating secondary cells; and activating and/or deactivating the secondary cells in accordance with the HS-SCCH order, wherein the HS-SCCH order is applied to a subset of secondary cells. - View Dependent Claims (7, 8)

9. A method for activating and deactivating secondary cells, the method comprising:
-
activating at least one secondary cell; monitoring activity on the secondary cell or a group of cells including the secondary cell using an inactivity timer; and deactivating the secondary cell or all secondary cells in the group autonomously on a condition that the inactivity timer associated with the secondary cell or the group of cells expires, wherein the inactivity timer is initialized upon activity on the secondary cell or a group of cells including the secondary cell. - View Dependent Claims (10)
