Abstract: Signal processing delays are selected from a candidate set in a wireless receiver based on both present and past channel behavior. According to one embodiment, a subset of signal processing delays are selected for received signal processing by accumulating a history of periodic delay selection computations for a candidate set of signal processing delays during a time interval. The delay selection calculations are based on cross-correlations between different ones of the signal processing delays. At the end of the time interval, a subset of the signal processing delays are selected from the candidate set of delays for received signal processing based on the history of delay selection computations.

Abstract: A method and apparatus adapted to adjust threshold values for initiating HO measurements based on terminal or user equipment (UE) performance. The threshold values for initiating the HO measurements and for executing the HO may be determined by the network. Prior to determining whether to proceed with these procedures, the thresholds are adjusted, based on the actual UE performance. This adjustment is achieved by applying an offset in dB that captures the effective SIR improvement of the advanced receiver compared to the standard receiver used to set the thresholds. The offset depends on, among other things, the receiver type used, the number of receiver antennas, the multi-path channel profile, the number of active radio links, and the services/connection modes that are currently active in the UE.

Abstract: An arrangement, control unit, and method in a cellular telecommunication system for allocating packets in a packet data stream to different base stations for transmission to a mobile terminal. The control unit receives the packet data stream in a main queue and identifies a plurality of base stations having sufficient signal strength to communicate with the mobile terminal. A data splitter splits the data stream into a number of sub-streams containing different data packets from the packet data stream. The sub-streams are buffered in a number of sub-queues, each of which is connected to a different base station. Packets are allocated to the sub-queues to maintain equal numbers of packets in each sub-queue, or to maintain a specified quality of service level for each sub-stream. The base stations independently transmit their sub-streams to the mobile terminal. Error-control coding may be applied to the packets to enhance macro diversity benefits.

Abstract: Disclosed is a chip-level or a symbol-level equalizer structure for a multiple transmit and receiver antenna architecture system that is suitable for use on the WCDMA downlink. The equalizer structure takes into account the difference in the natures of inter-antenna interference and multiple access interference and suppresses both inter-antenna interference and multiple access interference (MAI). Enhanced receiver performance is achieved with a reasonable implementation complexity. The use of the CDMA receiver architecture, in accordance with this invention, enables the realization of increased data rates for the end user. The CDMA receiver architecture can also be applied in conjunction with space-time transmit diversity (STTD) system architectures.

Abstract: This invention is generally concerned with reduced power consumption signal processing methods and apparatus, and in particular with techniques for jointly controlling power supply voltage and clock frequency in a receiver to reduce power consumption. A method of reducing the power consumption of a data receiver is described. The receiver is configured to process a received signal using repeated implementations of substantially the same first data processing element, a rate of said repetitions being determined by a clock frequency of said first data processing element. The method comprises determining a number of repetitions of said repeated implementations of said first data processing element; processing said receiving signal according to said determined number of repetitions; adjusting said number of repetitions in response to a power saving control signal; and jointly reducing said clock frequency and a power supply voltage to said first data processing element in response to said control signal to reduce said receiver power consumption.

Abstract: Coded digital data symbols sent through a transmission channel of a communications network are received in a receiver. Estimates (y) represented by a first number (a+b) of bits are calculated, and modified estimates (y′) represented by a second number (c) of bits provided therefrom, the second number being lower than the first number. An amplitude value is calculated for each estimate (y), and an averaged amplitude value calculated for a number of amplitude values. A scaling factor (s) is calculated form the averaged amplitude value, and scaled estimates generated in dependence of die scaling factor. The scaling factor is used for a number of scaled estimates corresponding to the number of amplitude values for which the averaged amplitude value was calculated. Thus a better scaling factor is provided for most channel cases, which can still be calculated with the limited computational resources of a terminal for such networks.

Abstract: An exemplary receiver demodulates an amplitude modulated data signal received in association with a reference signal, wherein a transmit power of the data signal is unknown to the receiver circuit, by determining a scaling factor based on the reference and data signals. Thus, an exemplary receiver estimates scaling factors indicative of the received amplitude of a data channel signal that is transmitted at a power different from that of the reference channel being used to estimate the radio channel properties. The scaling factor may be used to correct the amplitude of information symbols recovered from a received data signal such that they are moved closer in amplitude to intended points within an amplitude modulation constellation and/or to scale nominal points in a reference constellation used in demodulating the received symbols.
