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.

摘要： A method for noise rise estimation in a wireless communication system comprises measuring (210) of received total wideband power of an antenna a plurality of times. An estimate of a noise floor measure is computed (212) based on at least a number of the measured received total wideband powers of the antenna. Interference whitening of a received signal is performed (214) per user for a multitude of users. A useful signal power per user after the interference whitening, preferably Frequency Domain Equalization, is determined (216). A noise rise measure per user is calculated (220), based at least on the useful signal power per user and the noise floor measure. The calculation in turn comprises compensation of the noise rise measure per user for the effects of the interference whitening. An arrangement for noise rise estimation is adapted for such a method. A radio base station comprises such an arrangement.

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： A method for uplink channel estimation comprises providing (210) of a channel state model in a channel estimator. An up-link radio signal of a present time slot is obtained (220) in the channel estimator as well as a series of transmit power control commands (230) 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 (232) based on measurements of the particular received uplink radio signal. Channel states are adapted (234) based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated (240) 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： The position of a mobile device served in a cell of a serving node of a wireless communication network is estimated by estimating an angle-of-arrival (AoA) between the mobile device and the serving node based on a precoding matrix indicator (PMI) determined for the serving node in a downlink direction or for the mobile device in an uplink direction. Also estimated is the AoA between the mobile device and a non-serving neighbor node of the wireless communication network based on a PMI determined for the neighbor node in the downlink direction or for the mobile device in the uplink direction. The downlink and/or uplink AoA estimation can be further enhanced by employing interference cancellation in the mobile device and in the radio node, respectively. The position of the mobile device is estimated based on the estimated AoAs.

摘要： A wireless device (24) receives a reference signal over a radio channel (21). The reference signal may be Positioning Reference Signals (PRS) and/or Common Referencing Signals (CRS), and may be transmitted from a transmitter (22). The wireless device (24) comprises a correlator (100); a reference signal detector (102); a threshold selector (106); and a reference signal analyzer (108). The correlator (100) use a signal received from the radio channel (21) and a replica of the reference signal to provide a correlator output value. The reference signal detector (102) compares the correlator output value with a threshold value to detect presence of a reference signal, and to estimate an arrival time of the reference signal. The threshold selector (106) adapts the threshold value to at least an estimate of a relative amount of noise and interference power in the received signal.
