Abstract

A method of controlling uplink transmission power in a communications network is provided. The network includes a network node and a mobile station. The mobile station is allowed to autonomously reduce its transmission power on a transmission channel until the network node signals a mobile station power level different from a predetermined power level to the mobile station. The network node controls the transmission power of the mobile station when said mobile station power level is signalled to the mobile station.
