Abstract: A method implemented to provide voice calls in a network. 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.

Abstract: The method an apparatus described herein manages uplink resources to increase spectral efficiency and system capacity. According to one embodiment of the present invention, a base station may be assigned two or more downlink carriers for downlink transmission and two or more corresponding uplink carriers.

The uplink carriers can be operated at different interference levels and the uplink traffic can be divided between the available uplink carriers based on the type of traffic and/or data transmission parameters. The mobile terminals may also be allowed to switch between the uplink carriers to improve overall efficiency.

Abstract: The quality of a received signal in a non-linear receiver is estimated using a coupling matrix G or Q that describes the interaction of symbols in the received signal with other symbols and/or how the impairment (noise and interference) interacts in the received signal. The coupling matrix is also useful for joint detection. The signal quality estimate may include, e.g., the minimum eigenvalue, and other functions, such as the determinant and trace of the coupling matrix. When G or Q varies with each block, as in CDMA systems employing longcode scrambling, a representative matrix can be used, such as a matrix of RMS values or average magnitudes of real and imaginary components. The signal quality estimate can be expressed as a bit error rate (BER).

Abstract translation: 使用描述接收信号中的符号与其他符号的相互作用和/或接收信号中的损害（噪声和干扰）如何相互作用的耦合矩阵G或Q来估计非线性接收机中的接收信号的质量 。 耦合矩阵对于联合检测也是有用的。 信号质量估计可以包括例如最小特征值和其他函数，诸如耦合矩阵的行列式和轨迹。 当G或Q随每个块变化时，如在使用长码扰码的CDMA系统中，可以使用代表性矩阵，例如RMS值矩阵或实部和虚部分量的平均幅度。 信号质量估计可以表示为误码率（BER）。

Abstract: A receiver comprises plural receive antennas and electronic circuitry. The plural receive antennas are configured to receive, on plural subcarriers transmitted over a radio interface, a frequency domain signal that comprises contribution from a block of time domain symbols. The electronic circuitry is configured or operable to perform symbol detection of time domain symbols comprising the block by performing a multi-stage joint detection procedure comprising plural stages, and thus serves as a detector (40). For a first stage the block is divided into a first number of sub-blocks each having a sub-block first size. For a second stage the block is divided into a second number of sub-blocks each having a sub-block second size, the sub-block second size being greater than the sub-block first size. For each stage a detector (40) formulates frequency domain combining weights and uses the frequency domain combining weights for combining multiple receive versions of each subcarrier to provide candidate symbol combination values for symbols in each sub-block of the respective stage. For the second stage the detector (40) is further configured to use the candidate symbol combination values of the first stage to formulate joint hypotheses to serve as candidates for the joint detection operation of the second stage.

Abstract: Methods and apparatus are disclosed for improving a precoder selection process in a wireless communications system. In a normal precoder selection process, a precoder is selected from a codebook based on channel state information estimated from received reference signals. In between two received reference signals, a subset of precoders is cycled through and each precoder in the subset is iteratively selected for use by a transmitter to precode transmit signals. The subset of precoders may be adaptively modified based on predefined criteria.

Abstract: A CDMA multi-code joint demodulation solution in which impairment suppression and channel matching operations are performed prior to despreading. Embodiments include a linear front end that performs chip-level suppression of signal components that are not included in a subsequent joint demodulation process. The pre-processing stage also carries out metric preparation and provides a vector decision statistic that is processed by a joint demodulation stage to extract per-code soft values for the symbols of interest in the received signal. Both code-specific and code-averaged versions of the linear processing are disclosed, as are several front-end configurations with equivalent performance, but different complexity trade-offs. These new approaches use a block formulation, requiring a set of input chip samples as an input, and perform all operations as matrix-vector multiplications, which is an approach amenable to efficient DSP or hardware implementation.

Abstract: In one aspect, the present invention improves Turbo equalization and/or soft interference cancellation processing in communication receivers by providing an efficient and accurate technique to compute the second moment of a received symbol, e.g., an interfering symbol, as a function of the expected bit values of only those bits in the symbol that are magnitude-controlling bits according to a defined modulation constellation. Advantageously, the expected bit values in at least one embodiment are computed using a LUT that maps bit LLRs to corresponding hyperbolic tangent function values. Further, the expected symbol value is computed as a linear function of terms comprising the expected bit values and the soft symbol variance is efficiently computed from the second moment and the expected symbol value squared. This simplified processing reduces receiver complexity, particularly in the context of modulation constellations having non-constant magnitudes, and thus saves power and/or improves design economics.
