ABSTRACT:
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, α, is determined by the determined pathloss estimate, producing a weighted pathloss estimate. (1−α) is multiplied to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate. 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 a target signal to interference ratio to a constant value.
