摘要： In MU-MIMO scenarios, a target mobile terminal can be exposed to data streams intended for other mobile terminals. If the target mobile terminal is capable of interference cancellation, then a serving base station can provide the target mobile terminal with interference information so that the target mobile terminal can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal or are allocated for common listening. The serving base station exchanges configuration information with neighboring base stations over inter-BS links. The inter-BS links use resources that are different from the radio resources used between the base stations and the mobile terminals.

摘要： Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

The method comprises receiving a voice call initiation request at a caller agent, wherein the voice call initiation request is triggered by a caller initiating a voice call via a caller equipment, wherein the voice call is destined to a callee equipment communicatively coupled with the network to reach a caller, and wherein the caller agent and a callee agent interact with the caller equipment and the callee equipment respectively. The method further comprise sending a call connection message to the caller equipment, receiving an acknowledgment message from the caller equipment, and opening a voice channel between the caller and the caller agent without waiting for a callee agent response.

摘要： Conventional mode adaptation does not account for the gain imbalance between channels for measurement and for data reception. Therefore, the precoder, which is selected based on the measurement channel, may not be the optimal precoder for the data reception channel. By maintaining relative SINR ordering between transmission modes, a receiver may select the transmission mode for a transmitter that maximizes the actual throughput even in the presence of inter-antenna gain increase or decrease.

摘要： The present invention relates to a method and arrangement to enhance the communication performance in wireless communication systems. The method of the invention provides better adjustment of reported SINR in MIMO, and PARC-MIMO based communication systems. According to the method information relating to signal-to-interference-plus-noise ratio is determined by the user equipment and reported to the base station. The base station adjust reported SINRs using a model of the SINR dependences of power and code allocation. The dependences is modeled by a function comprising a first parameter relating only to power allocation and a second parameter relating only to code allocation. The first parameter has a power allocation exponent and the second parameter has a code allocation exponent. Both the power allocation exponent and the code allocation exponent are data stream dependent.

摘要： A system and method to more efficiently compute updated Frequency Domain (FD) Minimum Mean Squared Error (MMSE) equalization weights in a multi-stage Parallel Interference Cancellation (PIC) receiver after initial interference cancellation. The updated equalization weights (which are to be used during re-equalization) can be obtained using the old equalization weights already computed for initial interference cancellation. There is no need to invert an nR by nR matrix (where nR is the number of receive antennas) at each stage of the PIC receiver during each iteration of equalization and decoding operations. Rather, the matrix to be inverted to obtain updated equalization weights may be of the dimension n×n (where “n” equals the total number of transmission layers in a transmission scheme used in the wireless network). This significantly reduces complexity of determining updated equalization weights during FD MMSE equalization, thereby saving computational resources in a digital receiver performing such equalization.

摘要： In a blind spreading factor detecting receiver, the amplitude of a desired signal term is decoupled from the spreading factor hypothesis for that signal. Furthermore, the amplitude of the desired signal and the variance of an associated impairment term are estimated, and the estimates used to form a spreading factor hypothesis. Additionally, in one or more embodiments, a suboptimal detector does not rely on estimates of the amplitude of the desired signal or variance of the impairment term. Rather, the detector relies on scaled values that are partially despread using an initial spreading factor not greater than the smallest possible spreading factor used by the signal of interest, and combined using combining weights from a Rake or G-Rake processor, wherein the scaling factor is chosen to yield a unity ratio between the signal amplitude and noise variance after scaling.

摘要： In one aspect, the present invention greatly simplifies soft modulation calculations, in part by exploiting certain properties of Gray-mapped QAM constellations used in modulating symbols of interest. In at least one embodiment, the simplified processing includes performing the soft modulation separately for the real and imaginary parts of each symbol of interest, by using the Gray mapping to decompose each of the real and imaginary parts into binary soft modulations for each bit, and then using a computationally-efficient table lookup to calculate the binary soft modulation. Here, the look-up table comprises pre-computed bit contributions to the complex soft symbol value to be formed for the symbol of interest.

摘要： Signal impairment correlations for multiple signals in a received multipath signal are constructed by fitting parametric models associated with each high-data-rate signal in the multipath against measured impairment correlations. The estimated model fitting parameters are applied to form impairment correlation estimates for all signals. The models comprise a separate impairment covariance matrix scaled by a model fitting parameter for each high-data-rate signal and a noise covariance matrix scaled by a noise element model fitting parameter. The model fitting parameters may be estimated by a least-squares formulation and applied to form impairment correlation estimates for all signals of interest. The resulting impairment correlation estimates may be provided to G-RAKE receivers or joint scaling demodulators to demodulate the signals while suppressing interference from the high-data-rate signals.
