Abstract: Methods to provide power control during a soft handover are provided, traditionally, power control is done by setting a target Signal to Interference (and noise) Ratio, SIR/SINR, target or a power target. Herein, and as in 3GPP contribution R1-131608, a rate adaptation method is used instead. The problem occurring during soft handover is that the non-serving cell may decode the UE transmissions better than the serving cell, but the serving cell, without this knowledge, may instead reduce the rate, hence reducing the gain of soft handover. It is therefore proposed to, at the RNC (which knows the HARQ retransmission performance from all cells in the active set) generate an uplink data rate offset value responsive to a retransmission indication, transmitting the uplink data rate offset value to the serving base station for transmission to the wireless terminal. Alternatively to the explicit uplink data rate offset, the RNC does not need to be aware that the UE is operating in rate adaptation mode, thus setting a target SIR or power as conventionally. It is the NodeB that interprets the SIR target changes as rate change commands.

Abstract: Mobile station positioning methods are calibrated using an error bias estimation for refining the determination of the mobile station location which does not require any added hardware to the telecommunications system. The position of the mobile station is calculated assuming no bias errors and a first order approximation of the mobile station position is derived as a function of the bias error. The bias error is then estimated and used to refine the previously calculated mobile station position.

Abstract: 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 (700 or 720) can be mapped onto a plurality of layers (702, 704 or 722, 724, 726) which are equal in number to a channel rank of a radio channel to be used for the transmission.

Abstract: 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 corection 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.

Abstract: 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.
