    Abstract: A system which dynamically adjusts the power of signals transmitted from a wireless base station over global channels to minimize spillover to other communication cells monitors the total transmit power of the base station and dynamically adjusts the global channel transmit power as a function of the total transmit power of the base station as measured at the base station.

    Abstract: Outer loop/weighted open loop power control controls transmission power levels 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 the first station on the basis of measured error rates of communications from the 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 communication from the second station to the first station is based on in part weighting the path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted from the first station.

    Abstract: The present invention provides a method for a communication system utilizing spreading code sequences, the system comprising: (a) a first generator which outputs a first repetitious code sequence at a first data rate; and (b) a second generator which outputs a second repetitious code sequence at a second data rate which is higher than the first data rate, wherein the first code sequence is truncated each time the second code sequence is repeated.
