摘要： Combined closed loop/open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. The first station transmits power commands based on in part a reception quality of the received communications. The first station transmits a first communication having transmission power commands based on in part a reception quality of the received communications. The first station transmits a first communication having a transmission power level in a first time slot. The second station received the first communication and the power commands. A power level of the first communication as received is measured. A path loss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. The second station transmits a first communication to the first station in a first time slot. The second communication transmission power level is set based on in part the path loss estimate weighted by a factor and power commands. The factor is a function of a time separation of the first and second time slots.
