Abstract:
A method for determining uplink power level in a wireless digital communication system comprising a base station and at least one user equipment (UE), comprising the steps of:(a) said base station transmitting a signal over a physical reference channel to the UE; (b) said UE calculating a path loss, responsive to the transmission over the physical reference channel, a power setting of which is known to the UE; (c) said base station, responsive to an uplink transmission from the UE, measuring uplink interference level for time slots in which the UE transmits; (d) said base station, allocating a specific uplink control channel indicating uplink interference level in the channel, said allocation and indication being transmitted to the UE; (e) said UE determining an uplink power level based on current path loss calculated by the UE and said indication; and (f) initiating an uplink control channel transmission to the base station having the power level determined at step (e).
