摘要： In a transmitter or transceiver, codewords from HARQ processes can be mapped or assigned to various layers for transmission and/or retransmission of information on a radio channel. Exemplary embodiments provide for various mappings which facilitate, for example, HARQ processes. For example, a codeword can be mapped onto a plurality of layers which are equal in number to a channel rank of a radio channel to be used for the transmission.

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 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.
摘要翻译：本发明涉及移动终端的卫星定位。提供了对在移动终端测量的参数中的错误进行校正的定位。首先计算终端位置（S2; S4'），无误差校正或部分纠错。因此，定义了一组具有UE位置和UE时钟偏差以及可能的传输时间偏移作为未知数的非线性方程，对于移动终端位置进行线性化和求解。确定结果的质量并将其与预定标准进行比较（S3; S5）。如果不符合质量标准，则通过附加的纠错重新计算移动终端的位置（S4，S4'; S6）。所提出的方法可以涉及对信号接收时间的参数中的错误或伪距参数或两者中的错误进行校正。误差校正可以是逐步的。

摘要： A mobile communication station in a wireless communication network is used to measure the respective times of arrival of radio signals respectively transmitted by a plurality of radio transmitters in the network. The mobile communication station is provided with real time difference information indicative of differences between a time base used by a radio transmitter serving the mobile communication station and respective time bases used by the other radio transmitters. The mobile communication station determines, in response to the real time difference information and relative to the time base used by the radio transmitter serving the mobile communication station, a plurality of points in time at which the respective radio signals are expected to arrive the mobile communication station. For each radio signal, the mobile communication station monitors for arrival of the radio signal during a period of time after the point in time at which the radio signal is expected to arrive.

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.
