Abstract  Abstract

A method and an apparatus for synchronizing radio links and power control in CELL_FACH and in Inactive mode are disclosed. A wireless transmission / reception unit (WTRU) transmits a preamble on the random access channel (RACH) and receives a acquisition indicator that confirms the preamble on RACH via an acquisition indicator channel (AICH) and an index to a resource in the enhanced dedicated channel (E-DCH). The WTRU determines a start of a frame in E-DCH. A timing offset in F-DPCH is defined with respect to one of the access intervals in RACH and an access interval in AICH bearing the acquisition indicator. A relative F-DPCH timing offset can be signaled to the WTRU and the WTRU can determine an E-DCH frame start based on the relative F-DPCH timing offset and the timing of an access interval in AICH which includes the acquisition indicator. The WTRU can transmit a power control preamble on the dedicated physical control channel (DPCCH) before starting a transmission on E-DCH.
