摘要： A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.
摘要翻译：基站通过将PRS编码为第一组传输资源，将其它信息编码为第二组传输资源，将无线通信设备中的定位参考信号（PRS）传送到无线通信系统中的下行链路，的资源转换成子帧，使得第一资源集合基于与基站相关联的标识符被多路复用到第一组正交频分复用（OFDM）符号的至少一部分中，并且第二组资源被多路复用为第二组OFDM符号。在接收到子帧时，无线通信设备基于与发送子帧的基站相关联的标识符来确定哪个传输资源集合包含PRS，并处理包含PRS的资源集合以估计定时（例如，到达时间）信息。

摘要： First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.
