摘要： Systems and methods according to these exemplary embodiments provide for methods and systems for improving the signal-to-interference-plus-noise ratio (SIR) estimation between a mobile communications device and a base station (BS) for improving power control. A first SIR estimate is generated (802) based on signals received on at least a first channel and a second SIR estimate is generated (804) based on signals received on a second channel. A correction factor for the second SIR estimate is generated (806) based on at least the first SIR estimate, and the second SIR estimate is adjusted (808) with the correction factor. The first SIR estimate can, optionally, be generated using channel coefficients generated from signals received on both the first channel and the second channel.

摘要： Channel estimation accuracy is improved by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel allocated to the same receiver. The physical control channel may be a DPCCH, E-DPCCH or other type of physical control channel allocated to a receiver for facilitating uplink or downlink communication. Regardless, the control channel power level is optimized for channel estimation as a function of data transmission rate and/or transport format. In one embodiment, control channel symbols are transmitted for use in channel estimation by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a physical data channel allocated to the receiver (200). Control channel symbols are transmitted to the receiver over the physical control channel at the adjusted power level (202). The receiver uses the control channel symbols to perform channel estimation (204).

摘要： The present application describes a new path search and verification method and apparatus for identifying and selecting one or more delays for a receiver. A front-end receiver receives a signal having one or more signal images, where each signal image has a corresponding signal delay. A tree generator builds a hierarchical delay tree from a plurality of delay nodes, each corresponding to one of the signal delays. A tree searcher searches through the delay tree to identify one or more surviving delay nodes, where each surviving delay node corresponds to a candidate delay for the receiver. The receiver may also include a state machine comprising a plurality of ordered states for providing candidate delays for the receiver. The state machine stores the candidate delays and shifts the candidate delays between states within the state machine based on the latest results from the tree searcher.

摘要： A wireless communication receiver, such as the receiver included in a wireless communication transceiver implemented in a base station or in a mobile station of a wireless communication network, includes a parametric G-RAKE receiver circuit and a method that compute parametric scaling parameters on a per transmission interval basis. In one embodiment, measured impairment correlations are obtained for an individual transmission slot and used to estimate instantaneous values of the scaling parameters. One or both of those instantaneous values are then constrained according to one or more defined limits. In other embodiments, multiple transmission slots are used to increase the number of measurements available to estimate the scaling parameters, with parameter constraining optionally applied. Further embodiments use iterative methods and/or solve for one parameter, and use the results to obtain the other parameter(s). One or more of these embodiments can be improved through the use of error correction/detection information.

摘要： A receiver based on a RAKE receiver architecture includes a logic circuit configured to assign one or more RAKE fingers to a finger placement grid that is independent from a searcher delay grid used by the receiver's searcher in generating multipath delay profiles for received signals. The logic circuit may use the multipath delay profile to "tune" the finger placement grid relative to the searcher delay grid but the delay resolution of the finger placement grid is independent of the searcher delay grid. This independence permits, for example, setting the finger placement grid to a delay resolution based on a Nyquist criterion independently from the delay resolution used by the searcher. The receiver may use two or more finger placement grids, may operate in a mixed mode where fingers are assigned on- and off-grid, and may operate selectively in grid or non-grid modes.

摘要： A parallel interference cancellation (PIC) receiver incrementally removes interference from signals in parallel modules in successive stages. For each desired signal, as interfering signals are removed, corresponding updates to a data covariance matrix are modeled as computationally tractable rank-one updates to a root matrix of the covariance matrix. Processing of signals and/or covariance information may be initiated, continued, and/or halted at various stages, e.g., in response to signal or data quality. The PIC receiver using root matrix updates is applicable to a variety of demodulation techniques.

摘要： Methods and apparatus for processing a composite communication signal comprising two or more received signals of interest are disclosed. An interference-suppressing receiver (10), which may comprise a G-Rake receiver or a linear chip equalizer, utilizes a square-root covariance matrix in processing received signals, where the square-root covariance matrix represents impairment covariance or data covariance for the composite communication signal. In an exemplary method, a receiver (10) detects symbols, corresponding to a signal of interest, from the composite communication signal, using processing weights calculated from a square-root covariance matrix and a net channel response for the signal of interest. The method further comprises calculating a reconstructed version of the signal of interest from the detected first symbols, generating an updated communication signal by subtracting the reconstructed version of the first signal of interest from the composite communication signal, and updating the square-root covariance matrix to obtain an updated square-root covariance matrix.

摘要： The present invention relates to broadcasting in a cellular communications system. An object of the present invention is to broadcast user data according to a hierarchical data layer model, whereby a basic data layer has superior coverage in the cell and provides for a basic QoS. Enhanced data layers are available in addition to the basic data layer, albeit with less wide coverage in the cell, and provide for a higher QoS than if the basic layer only was detected. According to the invention the hierarchical model is provided by channel coding the different data layers at different coding rates. The coded data layers are multiplexed on a physical channel separately from the modulation and broadcasted in the cell. An advantage with the solution is that robust modulation methods may be used, and flexibility in the allocation of resources to the different layers.
