Methods and Arrangements in a Wireless Communications System

摘要

The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL_FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.

主权项

1. A user equipment of a wireless communication network capable of entering a transmission procedure, wherein the type of transmission procedure is a random access procedure, the user equipment comprising:
a receiver operative to receive at least a first set of transmission control parameters associated with a timing for entering an enhanced uplink procedure when the user equipment is in CELL_FACH state, the first set of transmission control parameters chosen to reduce a delay of access in comparison to an access time for access by the user equipment to ordinary uplink resources using a standard random access channel (RACH) procedure when the user equipment is not in CELL_FACH state; and a microprocessor configured to:
derive the timing for entering the transmission procedure using the first set of transmission control parameters, when initiating an enhanced uplink procedure when the user equipment is in CELL_FACH state, andenter the enhanced uplink transmission procedure according to the derived timing.
