摘要： A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a NACK as opposed to an ACK determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

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： A wireless communication system and method for controlling transmission power to maintain a received signal-to-interference ratio (SIR) as close as possible to a target SIR. A received quality is maintained as close as possible to a target quality based on block error rate (BLER). When a target BLER is converted to an initial target SIR, an error may occur due to a channel condition mismatch, since the target SIR required for the target BLER varies with channel conditions. An outer loop power control process is used to set a target SIR for each coded composite transport channel (CCTrCH) based on the required target BLER. The process adjusts a SIR step size parameter to maximize the convergence speed of the process.

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 wireless communication system. 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.

摘要： A transmission power level for a user equipment in a wireless time division duplex communication system using code division multiple access is determined. An interference level is measured. A pathloss estimate is determined. A long term average of pathloss estimates is determined. A first weighting factor, α, is determined by the determined pathloss estimate, producing a weighted pathloss estimate. (1−α) is multiplied to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate. A transmission power level of the user equipment is determined 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： A spread spectrum time division duplex user equipment uses frames with time slots for communication. It receives power commands and receives a first communication having a transmission power level in a first time slot. It measures a power level of the first communication as received and determines a pathloss estimate based on in part the measured received first communication power level and the first communication transmission power level. The user equipment sets a transmission power level for a second communication in a second time slot from the user equipment based on in part the pathloss estimate weighted by a quality factor and adjusted by the power commands.
