摘要： The present invention relates to a method of adjusting transmission power on a downlink radio channel in a communication system comprising a user equipment and a base station. In the method uplink power headroom is determined by dividing a maximum transmission power of the user equipment by a transmission power of a control channel of the user equipment and the determined uplink power headroom value is sent to the base station. Then uplink path loss estimate is determined between the user equipment and the base station based on the uplink power headroom. Then an estimate for the downlink path loss is derived and finally the transmission power of the downlink radio channel is adjusted taking into account the downlink path loss estimate.

摘要： A spread spectrum modulator converts input sequences composed of digital symbols into n≧2 spread-spectrum sequences. The spread spectrum modulator can generate spreading code and can combine the spreading code with the input sequences to produce the n spread spectrum sequences for transmission from n respective antennas of a radio transmitter. Each spread spectrum sequence corresponds to a sum of at least two contributions mutually shifted by a time substantially less than the duration of a symbol, each contribution being the product of a version of one of the n input sequences times the spreading code.

摘要： A signal received by a base station is fed to a set of filters matched to spreading codes allocated to pilot channels originating from radio terminals. The outputs from the matched filters are processed so as to estimate parameters comprising, for each channel, eigenvectors representing propagation paths associated with respective amplitudes of reception along these paths. The processing of the output signals from the matched filters comprises an estimation of parameters for a first channel received with a fairly high power by the base station, a correction of the output from the matched filter of a second channel having less energy, taking account of at least one of the eigenvectors of the first channel, and an estimation of parameters for this second channel on the basis of the modified output from said matched filter.

摘要： The received radio signal includes contributions from a plurality of channels multiplexed by respective spreading codes. A matched filter receiver is allocated to each multiplexed channel to estimate an impulse response of the channel and to provide first soft estimates of symbols transmitted on the channel. The first soft estimates provided by the matched filter receivers are processed to obtain a corrected soft estimate of at least one symbol transmitted on a channel. That processing includes subtracting from the first soft estimate of the symbol at least one term equal to the product of a decision value assigned to another symbol transmitted on another channel, determined from a soft estimate obtained previously for said other transmitted symbol, and a correlation between two generalized codes associated respectively with said symbol and with said other symbol. The generalized code associated with a symbol transmitted on a channel is a convolution of the estimated impulse response of said channel and Q samples of the spreading code of the channel which correspond to said symbol.
