Abstract  Abstract

A method and apparatus for radio link synchronization and power control in CELL_FACH state / idle mode is disclosed. The WTRU sends a RACH preamble and receives an acknowledgment indication that acknowledges the RACH preamble via the index of the AICH and E-DCH resources. The WTRU determines the start of the E-DCH frame. The F-DPCH timing offset is defined for one of the RACH access slot and the AICH access slot that carries an acknowledgment indication. The relative F-DPCH timing offset can be notified to the WTRU, and the WTRU may determine the start of the E-DCH frame based on the relative F-DPCH timing offset and the timing of the AICH access slot including the acknowledgment indication. it can. The WTRU may transmit a DPCCH power control preamble before starting E-DCH transmission.
