    摘要： A method for downlink power control for use in a spread spectrum time division communication system having time slots for communication, implemented in a user equipment, includes receiving data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots. An interference power for each time slot of the plurality of time slots is measured and a single power command for the entire CCTrCH is transmitted in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot. A subsequent data is received in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.

    摘要： A method of using a mobile unit in a multi-cell communication system to determine whether to commence handover of the mobile unit from a serving base station located in a first cell of the communication system to a target base station located in a second cell of the communication system. The mobile unit determines the serving base station received signal code power (RSCPser), the first cell interference signal code power (ISCPser), the target base station received signal code power (RSCPtar) and the second cell interference signal code power (ISCPtar). If the ratio RSCPser/ISCPser is less than the ratio RSCPtar/ISCPtar, the mobile unit commences handover to the target base station. The multi-cell communication system may be a time division duplex (TDD) system. The mobile unit may send a message to a radio network controller (RNC) in communication with the serving and target base stations to initiate the handover.

    摘要： The invention includes various approaches to assigning codes in wireless code division multiple access communication systems. The invention estimates the cross code correlation between codes to base the code assignment. One approach assigns codes having a high cross correlation to users having a low transmission power level. Another approach assigns code groups having a high cross correlation to a same coded composite transport channel. Another approach assigns codes using a cross correlation factor of each code to minimize a system noise rise. Another approach uses transmission or reception diversity to assign bad code groups to users having a different diversity relationship. Another approach uses a diversity factor and a cross code correlation factor to assign codes.

    摘要： A user equipment (UE) for a wireless time division duplex communication system which uses code division multiple access. The system communicates using communication bunts that have unique channelization codes and corresponding midamble codes where each midamble code is uniquely related to one or more channelization codes. The UE has a midamble detector which detects each midamble code in a received communication burst. A logic block determines the channelization codes related to each detected midamble and a channelization code detector detects channelization codes from among channelization codes determined by the logic block. A multiuser detection device recovers data from the received communication burst based on the detected channelization codes. Where all midamble codes are uniquely related to one channelization code, the channelization code detector is not needed.

    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.
