    • Methods and apparatus enabling a wireless network to generate data that can be used by a receiver (e.g., UE) to resolve the contributions of individual transmitters, such as to determine its location without resort to external devices such as GPS satellites. In one embodiment, the wireless network comprises a single frequency network (SFN), and a unique base station identifier is embedded within the data, and encoded in a manner which allows the UE to calculate path characteristics (such as path latency, and Direction of Arrival) to triangulate its position. In one variant, the data encoding comprises weighting frames of data from different base stations using an orthogonal matrix. Advantageously, the encoding and embedded identifier are also transparent to legacy UE, thereby allowing for implementation with no infrastructure or UE modifications other than software. Network and user apparatus implementing these methodologies, and methods of doing business, are also disclosed.
    • 使得无线网络能够生成可被接收器(例如,UE)用来解析各个发射器的贡献的数据的方法和装置,诸如以确定其位置而不借助于外部装置等 作为GPS卫星。 在一个实施例中,无线网络包括单频网络(SFN),并且唯一基站标识符嵌入在数据内,并且以允许UE计算路径特性(诸如路径延迟和方向 抵达)三角形的位置。 在一个变体中,数据编码包括使用正交矩阵对来自不同基站的数据帧进行加权。 有利地,编码和嵌入的标识符对于传统UE也是透明的,由此允许在除了软件之外没有基础设施或UE修改的情况下实现。 还公开了实施这些方法的网络和用户设备以及开展业务的方法。
