Abstract:
1. A method for radio link synchronization and power control in CELL_FACH state, the method comprising: receiving a system information block (SIB) including an offset value, wherein the SIB includes an indicator of a subset of access slots for transmitting a random access channel (RACH) preamble associated with an enhanced dedicated channel (E-DCH); transmitting RACH the preamble, wherein the RACH preamble is transmitted in at least one of the subset of indicated access slots; receiving an acquisition indicator in response to the RACH preamble; receiving a fractional dedicated physical channel (F-DPCH) according to a F-DPCH reception starting time, the F-DPCH reception starting time beginning a relative F-DPCH timing offset parameter after a start of an acquisition indicator channel (AICH) access slot including the acquisition indicator, wherein the relative F-DPCH timing offset parameter is 256 chips multiplied by the offset value; and transmitting a dedicated physical control channel (DPCCH) and an enhanced dedicated channel (E-DCH) after reception of the F-DPCH, wherein the DPCCH is transmitted according to a DPCCH transmission starting time, wherein the DPCCH transmission starting time and the F-DPCH reception starting time are offset by a predetermined offset.
