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.
