摘要： Method and apparatus for computing a noise power estimate in a wideband CDMA (WCDMA) network are disclosed and may include calculating a noise power estimate for a downlink channel based on an orthogonal sequence generated for a transmitted signal. The orthogonal sequence may be generated based on a slot number of the transmitted signal and/or a transmit diversity mode used for the transmitted signal. A portion of a plurality of dedicated physical channel (DPCH) pilot bits for the downlink channel may be summed to generate an in-phase (I) component and a quadrature (Q) component. The generated I component and the generated Q component may be multiplied by the orthogonal sequence to generate at least one noise I component and at least one noise Q component.

摘要： A maximum signal energy level among a plurality of individual distinct path signals in a wirelessly received signal cluster is detected. An early aggregate power level associated with at least a portion of the plurality of individual distinct path signals received at time instants preceding a first moment time, and a late aggregate power level associated with at least a portion of the plurality of individual distinct path signals received at time instants subsequent to the first moment time are computed. The first moment time, which corresponds to the detected maximum signal energy level, is adjusted based on the early aggregate power level and the late aggregate power level. At least a portion of the plurality of individual distinct path signals is received at a corresponding plurality of time instants within a duration comprising a delay spread of the wirelessly received signal cluster based on the adjusted first moment time.

摘要： Method and system for data-rate control by randomized bit-puncturing in communication systems. An encoder encodes at least one information bit thereby generating a group of encoded bits or an encoded frame. The encoder may be any type of encoder including a turbo encoder, an LDPC (Low Density Parity Check) encoder, a RS (Reed-Solomon) encoder, or other type of encoder. Any sub-portion of an encoded frame generated by such an encoder can be viewed as being a group of encoded bits. If the encoded frame is sub-divided into multiple groups of bits, each group can under processing in accordance with the means presented herein to effectuate rate matching. Based on a number of bits to be punctured from the group or frame generated by the encoder, a set of pointers and random-generated displacements is used to generate addresses for bits in the group or frame to be transmitted or punctured.

摘要： A mobile device estimates channel state information (CSI) comprising, for example, CQI and/or SNR, for a downlink channel. The estimated CSI is non-uniformly quantized and transmitted to the base station over a finite-rate feedback channel. Different portions of the estimated CSI are quantized using different quantization step sizes, which are determined according to a performance metric function such as a channel capacity function of the estimated CSI. A quantization step size for a portion of the estimated CSI is increased if a low distribution probability is indicated by the portion of the estimated CSI. A quantization step size for a portion of the estimated CSI is decreased if a high distribution probability is indicated. The mobile device quantizes the estimated CSI using the determined quantization step sizes to transmit to the base station over the finite-rate feedback channel. Downlink data transmission is received according to the transmitted CSI.
