    摘要： The present invention provides embodiments for producing a user equipment identification scrambling sequence (UEIDSS). The produced sequences for different user identification codes have a high separation. A base station uses the UEIDSS to scramble a high speed shared control channel (HS-SSCH) and a user equipment (UE) uses the UEIDSS to descramble the HS-SSCH. The embodiments utilize various blocks for producing the codes. These blocks include Reed-Muller encoding, concatenation, rate matching, segmentation, convolutional encoding, tail bit discarding, zero padding, repeating, CRC calculation, quadratic residue coding, parity-check bit, shortening, puncturing and BCH encoding blocks.

    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. At the second communication station, the first communication and the power commands are received. A power level of the first communication as received is measured. A pathloss estimate is determined based on in part the measured received first communication power level and the first communication transmission power level. A transmission power level is set for a second communication in a second time slot from the second station to the first station based on in part the pathloss estimate weighted by a quality factor and the power commands.

    摘要： A wireless communication method and apparatus for coordinating Node-Bs during handover for enhanced uplink (EU) transmission. In one embodiment, a radio network controller (RNC) initiates an inter-Node-B soft handover. A wireless transmit/receive unit (WTRU) establishes communication connections with a plurality of Node-Bs. A particular one of the Node-Bs is designated as being a primary Node-B, and each of other Node-Bs are designated as being a non-primary Node-B. The RNC informs all of the Node-Bs that the particular Node-B is a primary Node-B. The primary Node-B schedules EU transmission and performs ACK/NACK during soft handover. In another embodiment, the RNC initiates a hard handover for a WTRU connected to a source Node-B. The RNC sends an activation timer to the source Node-B to set the time for handover. As many previously negatively acknowledged (NACKed) data packets as possible are prioritized for retransmission in the source Node-B before the activation timer expires.

    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 target signal to interference ratio is provided. The target signal to interference ratio is updated using outer loop power commands. 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 the updated target signal to interference ratio to a constant value.

    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： An apparatus and method is provided for dynamic range power control of a wireless downlink communication signal, such that target signal quality adjustments are held temporarily when it is apparent that transmit power control commands will not produce the desired response at the transmitting station. Comparisons of measured received signals to thresholds are performed to determine whether the transmitting station has either reached the maximum or minimum transmit power, in which case the target signal quality adjustment is controlled accordingly. When normal transmit power is detected, the target signal quality adjustments are allowed to resume as usual.

    摘要： A method for outer loop power control in a wireless communication system begins by determining if a cyclic redundancy check (CRC) is available. If the CRC is available, the method uses the CRC to calculate an adjustment for a target signal to interference ratio (SIR) for a coded composite transport channel (CCTrCH). If the CRC is not available, then quality measurements of the CCTrCH are taken. The quality measurements are used to calculate an adjustment for the target SIR, which is then updated.
