    • Systems and techniques for determining the location of user equipment (UE) in a wireless network are disclosed. These techniques leverage geometric calculations for an overlaid bin grid framework mapping the wireless network area to store differential values for each frame of the bin grid framework for each pair of relevant NodeBs. A timing offset can be determined, such that when a time value from a target UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the target UE time value can be search for in the pre-computed differential value data set indexed by a relevant NodeB site pair to return a set of frames (forming a hyperbola between the site pair) that can be intersected with a second set of frames for a second NodeB site pair for the same UE. The intersecting frames can represent the location of the UE in the wireless network. Further, the data can be leveraged to correct timing in the network.
    • 公开了用于确定无线网络中的用户设备(UE)的位置的系统和技术。 这些技术利用覆盖的网格框架的几何计算,绘制无线网络区域以存储每对相关节点B的每个框架框架的差分值。 可以确定定时偏移,使得当来自目标UE的时间值被访问时,可以以最小的实时计算快速确定位置。 在一个方面,可以在由相关的NodeB站点对索引的预先计算的差分值数据集中搜索目标UE时间值,以返回一组帧(形成站点对之间的双曲线),该组可以与 用于同一UE的第二节点B站点对的第二组帧。 相交帧可以表示UE在无线网络中的位置。 此外,可以利用数据来校正网络中的定时。
