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.

摘要： GPS and A-GPS based positioning methods can be used to determine UE locations to enable location based services to be provided. However, if a UE does not have such receivers or the wireless network is not able to provide assistance, these methods will not be applicable. An alternative is to use OTDOA measurements using positioning reference signals transmitted by cells of the network. By optimizing the set of cells transmitting their positioning reference signals on different positioning occasions and properly configuring the muting patterns, interference can be minimized and the UE location can be readily determined.
摘要翻译：可以使用基于GPS和A-GPS的定位方法来确定UE的位置，以便提供基于位置的服务。然而，如果UE没有这样的接收机或者无线网络不能提供帮助，则这些方法将不适用。另一种方法是使用OTDOA测量，使用由网络单元传输的定位参考信号。通过在不同的定位场合优化传输其定位参考信号的小区集合并且适当地配置静音模式，可以最小化干扰并且可以容易地确定UE的位置。

摘要： Techniques are disclosed for determining measurement uncertainty of and/or multipath effects on positioning measurements, based on the residual deviations between timing measurements and high-accuracy location results. An example method begins with collecting (510) a plurality of timing measurements or ranging measurements, or both, each measurement corresponding to at least one anchor node antenna having a known location. A measurement deviation is determined (520) for each measurement by comparing the measurement to a corresponding reference location. The measurement deviations are used (530) to estimate measurement quality for one or more subsequent positioning measurements, and/or uncertainty associated with one or more subsequent positioning estimates, and/or an effect of multipath on subsequent positioning measurements or estimates. In some embodiments, a covariance matrix is calculated from the measurement deviations and is used to determine statistical information or multipath effects for measurements corresponding to a particular one of the anchor node antennas.
