ABSTRACT:
At a first communication station, communications from a second communication station are received. The first station transmits power commands based on in part a reception quality of the received communications. From the first communication station, a first communication having a transmission power level in a first time slot is transmitted. At the second communication station, the first communication and the power commands are received. A power level of the first communication as received is measured. A pathloss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. A transmission power level is set for a second communication in a second time slot from the second station to the first station based on in part the pathloss estimate weighted by a quality factor and the power commands.
