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, a physical layer message for activating a supplementary carrier; activating the supplementary carrier when the physical layer message for activating the supplementary carrier is received via the anchor carrier; receiving, via the anchor carrier or the 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, wherein the activation of DRX is common to both the anchor carrier and the supplementary carrier.
