摘要： A method for uplink channel estimation comprises providing of a channel state model in a channel estimator. An uplink radio signal of a present time slot is obtained in the channel estimator as well as a series of transmit power control commands issued for controlling a transmit power of the uplink radio signal. A delay between the time a transmit power control command is issued and the time that the transmit power control command is applied is estimated based on measurements of the particular received uplink radio signal. Channel states are adapted based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated in the channel estimator, by tracking the demodulated uplink radio signal with the channel state model. A channel estimator performing such method is also described.

摘要： A method for equalizing a received radio signal in a WCDMA system, comprises receiving (210), in a radio receiver, of a digital radio signal spread by scrambling codes. A channel estimation is performed (230) on the received digital radio signal for a plurality of channels. The received digital radio signal is in an equalizer equalized (240) into an equalized digital radio signal. This equalizing is performed by combining a plurality of part signals, deduced from the digital radio signal, with a respective delay and a respective combining weight. The equalizing (240) comprises provision of the combining weights based on a signal impairment matrix having elements compensated for systematic colouring caused by said scrambling codes.

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： Allocation of cell IDs in a cellular communication system includes determining a candidate allocation pattern of primary and secondary synchronization signal sequences for a candidate set of two or more cells. A performance metric is applied to the candidate allocation pattern to ascertain a performance indicator for the candidate allocation pattern, wherein the performance indicator indicates a quality of positioning performance for the candidate set of two or more cells. Cell-specific positioning performance for each cell in the candidate set of cells can be considered to derive the performance indicator of the candidate allocation pattern. If the performance indicator indicates acceptable positioning performance, primary and secondary synchronization signal sequences are allocated to respective ones of base stations corresponding to the two or more cells in accordance with the candidate allocation pattern. Otherwise, the process is repeated for a different candidate allocation pattern.
