摘要： The present invention relates to a method of adjusting transmission power on a downlink radio channel in a communication system comprising a user equipment and a base station. In the method uplink power headroom is determined by dividing a maximum transmission power of the user equipment by a transmission power of a control channel of the user equipment and the determined uplink power headroom value is sent to the base station. Then uplink path loss estimate is determined between the user equipment and the base station based on the uplink power headroom. Then an estimate for the downlink path loss is derived and finally the transmission power of the downlink radio channel is adjusted taking into account the downlink path loss estimate.
