Abstract: A method and an apparatus for simultaneously receiving on two carriers and performing discontinuous transmission (DTX) and discontinuous reception (DRX) in dual cell high speed downlink packet access (DC-HSDPA) are disclosed. A wireless transmit/receive unit (WTRU) receives a message for activating DRX for at least one of an anchor carrier and a supplementary carrier and applies the same DRX pattern to the anchor carrier and the supplementary carrier upon reception of the message. The message may be received via a high speed shared control channel (HS-SCCH) order. The WTRU may activate or de-activate the supplementary carrier based on the physical layer signal. Upon activation of the supplementary carrier, the WTRU may apply the same DRX pattern on both the anchor carrier and the supplementary carrier. The WTRU may flush a hybrid automatic repeat request (HARQ) buffer associated with the supplementary carrier upon de-activation of the supplementary carrier.

Abstract: A method for use in a wireless transmit/receive unit (WTRU) for receiving data over physical downlink shared channels from different cells, monitoring physical downlink control channels of a first cell for downlink control information associated with the WTRU, and recovering data from the physical downlink control channel in response to the downlink control information.

Abstract: A synchronization procedure in a wireless network is disclosed. A network device receives, from a wireless transmit/receive unit (WTRU) in a CELL_FACH state, data via an enhanced dedicated channel (E-DCH). The WTRU may transition to a CELL_DCH state from the CELL_FACH state. The WTRU may transition to the CELL_DCH state without subsequently performing a synchronization procedure A.

Abstract: Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.

Abstract: A wireless transmit/receive unit (WTRU) sending a first data signal via an enhanced dedicated channel (E-DCH) is provided. The WTRU may reconfigure physical channel parameters based on a reconfiguration message. The WTRU may subsequently send a second data signal without performing a synchronization procedure.
