Claim:
1. A method implemented in a wireless transmit/receive unit (WTRU) for supporting dual cell high speed downlink packet access (DC-HSDPA), the method comprising: receiving, via an anchor carrier or a supplementary carrier, a physical layer message indicating activation of discontinuous reception (DRX); applying a same DRX pattern to both the anchor carrier and the supplementary carrier in response to the physical layer message indicating activation of DRX such that DRX cycles of the anchor carrier and the supplementary carrier are aligned in the DRX pattern, and wherein the activation of DRX is common to both the anchor carrier and the supplementary carrier; receiving data on the anchor carrier or the supplementary carrier during the DRX pattern; and upon receiving the data on the anchor carrier or the supplementary carrier, de-activating DRX and monitoring at least one of the anchor carrier or the supplementary carrier for a duration of an Inactivity_Threshold_for_UE_DRX_cycle.
