Abstract: Control of receiver antenna diversity is described in relation to apparatuses, user radio terminals, a method, and a computer program. The apparatus comprises an interface configured to obtain information on a power control procedure of a radio receiver and a processing unit configured to switch on/off a receiver antenna diversity branch of the radio receiver on the basis of a comparison between a predetermined condition and the information on the power control procedure.

Abstract: A common control channel is monitored with a first and a second receiver. A target quality is determined for that channel, which may be signaled from a network. A quality parameter for the channel is determined from the first and second receivers, and compared to the target quality (directly or indirectly). Responsive to the comparing, one of the receivers is then operated in a reduced performance mode which consumes less power, for which several examples are disclosed. The comparison for switching from full to reduced and back to full may use different thresholds, which may be dynamically adjusted autonomous of the network to maintain the target quality. The common control channel may be one with which a broadcast traffic channel is associated. Methods, apparatus and computer programs embodied on a memory are detailed.

Abstract: A method, apparatus and system for improving outer loop power control in a communications system. A quality value for a plurality of data channels is adjusted for the plurality of data channels, while maintaining a target value.

Abstract: A receiver for use in a CDMA telecommunications system is disclosed. The receiver includes at least one antenna for receiving signals from a CDMA channel, where the received signals include a desired user signal. The receiver also includes combining circuitry, for performing chip waveform filtering and maximal ratio combining, to produce mutually correlated chip estimates of the received signals. The receiver further includes an adaptive separator, for adaptively separating the mutually correlated chip estimates, and a correlator, for despreading the output of the adaptive separator to obtain an estimate for data symbols of the desired user signal. In addition, the receiver further includes estimating circuitry, coupled to the combining circuitry, for estimating a response of the channel, where the combining circuitry utilizes the channel response estimate as a reference.

Abstract: A receiver for use in a CDMA telecommunications system is disclosed. The receiver includes at least one antenna for receiving signals from a CDMA channel, an estimator for estimating an impulse response of the channel, and an adaptive equalizer. The estimator provides a reference for the adaptive equalizer, and the adaptive equalizer operates to estimate a transmitted chip sequence of the channel and to restore orthogonality among the received signals. The adaptive equalizer includes circuitry for utilizing a blind adaptive algorithm to estimate the transmitted chip sequence of the channel.
