ABSTRACT:
A base station transmits a reference signal. The base station receives a communication. The received communication has a transmission power level set by measuring an interference level; determining the pathloss estimate using the reference signal; determining a long term average of pathloss estimates; multiplying a first weighting factor, α, by the determined pathloss estimate, producing a weighted pathloss estimate; multiplying (1−α) to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate; and determining the transmission power level 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.
