摘要： A transmitting station performs closed loop power control prior to a transmission pause. A closed loop transmission power level prior to the pause is determined. A reference signal is received and a received power level of the reference signal prior to and during the transmission pause is determined. The measured reference signal received power levels are compared to a transmit power level of the reference signals to produce a pathloss estimate of the reference signal prior to and during the transmission pause. A new transmit power level is determined by adjusting the closed loop transmission power level by a change between the prior to and during pathloss estimates. A transmission power level of the transmitting station is set to the determined new transmit power level. A communication is transmitted at the set transmission power level.

摘要： 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.

摘要： A transmitting station receives a transmit power command and a reference signal. The transmit power command indicates an increase or decrease in transmission power for the transmitting station. A received power level of the reference signal is measured and the measured reference signal received power level is compared to a transmit power level of the reference signal to produce a pathloss estimate of the reference signal. A size of a change in transmit power level is determined using the pathloss estimate. A transmission power level of the transmitting station is adjusted in response to the transmit power command in an amount of the determined change in size. A communication is transmitted at the adjusted transmission power level.

摘要： Outer loop/weighted open loop power control apparatus controls transmission power levels in a spread spectrum time division duplex communication user equipment (UE). The user equipment receives a communication including an transmitted power level and measures its received power level. Based in part on the measured power level and the transmitted 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 user equipment is based on in part weighting the path loss estimate in response to the estimate's quality.

摘要： A signal-to-interference ratio (SIR) estimator for estimating a SIR of baseband signals which are received and processed by a data demodulator to provide demodulated signals to the SIR estimator. The SIR estimator receives the demodulated symbols from the data demodulator and estimates the average signal power of the demodulated symbols as a function of a median based average power value md and a mean based average power value me of the demodulated symbols for each quadrant of a quadrature phase shift keying (QPSK) constellation. The function is used to determine a minimum value m between md and me. The SIR estimator estimates the average effective interference power of the demodulated symbols and calculates the SIR by dividing the estimated average signal power of the demodulated symbols by the estimated average effective interference power of the demodulated symbols. The SIR estimator reduces bias effects on SIR estimation.

摘要： 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.

摘要： The present invention is a system and method which controls outer loop transmit power for transmission power of an uplink/downlink communication in a spread spectrum time division communication. The system receives a communication from a base station and determines an error rate on the received communication. The system then distinguishes between static and dynamic channels, produces a static adjustment value, and characterizes the dynamic channels to generate a dynamic adjustment value. The target power level is then adjusted by the static and dynamic adjustment values, setting the transmission power level.
