The invention relates to a system for power control in a cellular communication system. The power control may be operated ( 201 ) in a first mode of operation wherein power control data are determined in response to a quality parameter, such as a desired signal to noise ratio. The method further comprises entering ( 205 ) a reduced power mode of operation by communicating power down power control data between a base station and a communication unit. The base station and/or communication unit then proceeds to operate ( 207 ) in the reduced power mode by communicating power control data corresponding to a reduced transmit power level. The reduced transmit power level may specifically be zero. After a given duration, the base station and/or communication unit proceeds to exit ( 211 ) the reduced power mode by communicating power up power control data between the base station and the communication unit. |
