摘要： Method and apparatus are provided for processing a received signal for making a symbol estimate of a symbol included in a signal transmitted in a Multiple-Input-Multiple-Output (MIMO) system. In an example mode, the method comprises (1) providing at least a subset of precoding matrices which are candidates for use in transmission of an interfering signal in a MIMO system; (2) using the received signal and plural candidates of the subset to determine corresponding plural covariance matrices, each of the plural covariance matrices being formed using a corresponding candidate precoding matrix; (3) determining which of the candidates is a trace minimizing candidate which is associated with one of the plural covariance matrices that has a minimum trace value; (4) forming a weighting matrix using the trace minimizing candidate; and (5) using the weighting matrix to make the symbol estimation.

摘要： The present invention relates to a method and arrangement for achieving transformations of received positioning information according to a first reporting format to positioning information according to a second format such as to allow a seamless transformation and handling of the positioning confidence values, i.e. the probability that the terminal is actually located in the region determined by the applied positioning method. The method derives an approximation of the shape-defining parameters for the second reporting format such as to minimize a criterion function including the predefined target confidence value and determining the deviation of the confidence value for the approximated shape from the target confidence value.

摘要： A downlink Channel Quality Indicator (CQI) is estimated in two steps. Initially, one or more subsets of received reference symbols are selected. If the transmitter may transmit signals in one or more of two or more frequency bands, optimal frequency bands are selected based on a first subset of reference symbols. If the transmitter may transmit using one of two or more VACs, an optimal VAC is selected based on the first or a second subset of reference symbols. An SINR is subsequently calculated for the selected frequency band and VAC combination, based on more than the subset(s) of reference symbols.

摘要： The invention relates to satellite-based positioning of mobile terminals. Positioning with correction for errors in parameters measured at the mobile terminal is provided. The terminal location is first calculated (S2; S4′) without error correction or with partial error correction. Hereby, a set of nonlinear equations with the UE location and the UE clock bias and possibly the transmission time offset as unknowns are defined, linearized and solved for the mobile terminal location. The quality of the result is determined and compared to a predetermined criterion (S3; S5). If the quality criterion is not fulfilled, the location of the mobile terminal is recalculated with additional error correction (S4, S4′; S6). The proposed method can involve correction for errors in a parameter for time of signal reception, or in a pseudorange parameter, or both. The error correction can be stepwise.
