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： There is provided a method in a cellular telecommunications network, the cellular telecommunications network comprising at least a first cell and a second cell. The method comprises the steps of transmitting (302) first periodic physical signals, usable by a device to determine its location, to the first cell; and transmitting (304) second periodic physical signals, usable by a device to determine its location, to the second cell. The second periodic physical signals are synchronized with the first periodic physical signals and have a timing offset, such that the first periodic physical signals and the second periodic physical signals are not transmitted simultaneously. The method is characterized in that transmission of data or control signals to the first cell is inhibited when the second periodic physical signals are transmitted to the second cell.

摘要： A method in a signalling device for assisting in positioning of user equipment based on time measurements is provided. The signalling device is associated with an s-cell, which is recognized by the first network node as having limited functionality and is, therefore, not considerable for the user equipment as a candidate cell for serving the user equipment (for data transmission. The signalling device associated s-cell is part of a positioning neighbor list of neighbor cells. The neighbor cells in the list are configured to have time measurements performed thereon by the user equipment for enabling positioning. The signalling device is configured to transmit predefined reference signals in predefined subframes and according to a predefined pattern relating to preselected subcarriers and preselected time slots within a subframe. The signalling device obtains synchronization information and transmits reference signals according to the configuration and synchronized according to the obtained synchronization information. This enables the user equipment to receive and perform time measurements on the transmitted reference signals for positioning when the signalling device associated s-cell is in the positioning neighbor list.
