    摘要： A stopping rule for Turbo decoding that is applied for both good and bad code blocks is disclosed. If the iteration either converges or diverges, decoding is terminated. In an alternative embodiment, the result of the stopping rule testing may be used for H-ARQ acknowledgement generation: if the iteration converges, an ACK is generated and if the iteration diverges, a NACK is generated. Optionally, the maximum number of decoding iterations may be dynamically selected based on MCS levels.

    摘要： A user equipment (UE) with circuitry configured to determine a pathloss associated with a received signal. The circuitry is configured to receive an adjustment and adjust a value in response to the received adjustment. The circuitry is configured to determine a transmit power level based on multiplying the determined pathloss by a parameter and adding the adjusted value to a result of the multiplying, wherein the parameter is value in the range of 0 to 1. The circuitry is configured to transmit a signal at the determined transmit power level.

    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 method of signal processing in a wireless transmit receive unit (WTRU) including multiple input/multiple output (MIMO) functionality. The method includes the WTRU receiving a plurality of simultaneous signals, performing a first process on at least one of the plurality of simultaneous signals, transmitting a feedback signal based on the first process, and performing a second process on at least one of the plurality of simultaneous signals. The first process is a subset of the second process.

    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： 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.
