ABSTRACT:
The transmission power is adjusted of a Forward Access Channel (FACH) from a base station to a mobile user terminal in a network for mobile telecommunications. The method comprises steps as follows. The base station sends a signal at a first transmission power level to the mobile user terminal. The mobile user terminal then sends a report of one or more parameter values dependent upon measured signal quality provided a predetermined reporting criterion is met. The base station then adjusts its transmission power to the mobile user terminal in consequence so as to maintain the measured signal quality within acceptable limits.
