A transmission power level for a user equipment in a wireless time division duplex communication system using code division multiple access is determined. An interference level is measured. A pathloss estimate is determined. A long term average of pathloss estimates is determined. A first weighting factor, alpha, is determined by the determined pathloss estimate, producing a weighted pathloss estimate. (1-alpha) is multiplied to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate. A target signal to interference ratio is provided. The target signal to interference ratio is updated using outer loop power commands. A transmission power level of the user equipment is determined by adding the weighted pathloss estimate to the weighted long term pathloss estimate to the measured interference level to the updated target signal to interference ratio to a constant value.
