    Abstract: A method and apparatus for radio link synchronization and power control in CELL_FACH state and idle mode are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble and receives an acquisition indicator acknowledging the RACH preamble via an acquisition indicator channel (AICH) and an index to an enhanced dedicated channel (E-DCH) resource. The WTRU determines a start of an E-DCH frame. An F-DPCH timing offset is defined with respect to one of the RACH access slot and an AICH access slot carrying the acquisition indicator. A relative F-DPCH timing offset may be signaled to the WTRU and the WTRU may determine a start of an E-DCH frame based on the relative F-DPCH timing offset and timing of an AICH access slot including the acquisition indicator. The WTRU may transmit a dedicated physical control channel (DPCCH) power control preamble before starting an E-DCH transmission.

    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.
