摘要： An autonomous system with no Customer Network Investment is described, wherein the system is configurable to operate on in a band in addition to the LTE band. Such system allows the definition of hybrid operations to accommodate the positioning reference signals (PRS) of LTE and already existing reference signals. The system can operate with PRS, with other reference signals such as cell-specific reference signals (CRS), or with both signal types. As such, the system provides the advantage of allowing network operator(s) to dynamically choose between modes of operation depending on circumstances, such as network throughput and compatibility.

摘要： Systems and methods for determining a location of user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit (LMU) having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of the UE. Some systems may include multichannel synchronization with a standard deviation of less than or equal 10 ns. Some systems may include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.

摘要： Methods for determining a LOB of one or more user equipment (UE) in a wireless system employing Time Difference of Arrival (TDOA) is described. TDOA techniques are based on estimating the difference in the arrival times of reference signals from multiple receivers or from multiple emitters to a receiver. A particular value of the time difference estimate defines a hyperbola between the two receivers on which the handset may exist. When the distance between the receiving antennas is small relative to the distance of the emitter source (the handset) being located, then the TDOA is equivalent to the angle between the baseline of the sensors (receivers antennas) and the incident RF energy from the emitter. If the angle between the baseline and true North is known, then the line of bearing (LOB) and/or angle of arrival (AoA), can be utilized to determine the location of the UE.

摘要翻译：描述了在使用“到达时差”（TDOA）的无线系统中确定一个或多个用户设备（UE）的LOB的方法。 TDOA技术基于估计来自多个接收机或从多个发射机到接收机的参考信号的到达时间的差异。时间差估计的特定值定义手机可能存在的两个接收机之间的双曲线。当接收天线之间的距离相对于位于发射源（手机）的距离较小时，则TDOA等效于传感器（接收机天线）的基线和来自发射器的入射RF能量之间的角度。如果基线与真北之间的角度是已知的，则可以使用轴承线（LOB）和/或到达角度（AoA）来确定UE的位置。
