Abstract:
1. A method for radio link synchronization and power control in CELL_FACH state, the method comprising: transmitting a system information block (SIB) including an offset value, value, wherein the SIB includes an indicator of a subset of access slots associated with a random access channel (RACH) preamble; receiving the RACH preamble in at least one of the subset of access slots; transmitting an acquisition indicator in response to the RACH preamble; transmitting a fractional dedicated physical channel (F-DPCH) according to an F-DPCH time, the F-DPCH time being based on a relative F-DPCH timing offset parameter and timing 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 receiving a dedicated physical control channel (DPCCH) according to a DPCCH time, the DPCCH time and the F-DPCH time being offset by a predetermined offset.
