OUTER LOOP/WEIGHTED OPEN LOOP POWER CONTROL IN A TIME DIVISION DUPLEX COMMUNICATION SYSTEM

摘要

Outer loop/weighted open loop power control controls transmission power leve ls in a spread spectrum time division duplex communication station. A first communication station (110) transmits a communication to a second communication station including target adjustment information generated at t he first station on the basis of measured error rates of communications from th e second station to the first station. The second station receives the communication and measures its received power level. Based on in part the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communicatio n from the second station to the first station is based on in part weighting t he path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted fro m the first station.
