摘要： Techniques are provided which may be implemented in various methods and apparatuses to allow an electronic device to determine when it transitions between certain environments which may be perceived, for example, from observations associated with wireless signals transmitted by a wireless communication network. In response to an environment transition determination, the techniques further allow for one or more positioning functions to be operatively affected in some manner.

摘要： Techniques are provided for frequency and/or timing synchronization of a small base station with a network. In one example, small base station may be configured to detect a macro signal of a macro base station, and set a frequency reference based at least in part on the macro signal, in response to the macro signal being available in a different band than that for the small base station. The small base station may be configured to set the frequency reference based at least in part on a Global Positioning System (GPS) signal, in response to detecting that the different band macro signal is not available.

摘要： Methods and apparatus are provided for use in peer-to-peer positioning operations in wireless networks. A method includes receiving a peer-to-peer trilateration (PPT) request message from another device over a wireless communication link, transmitting at least a first PPT beacon signal during at least a first portion of a first assigned time slot, in response to the PPT request message, and selectively transmitting at least a second PPT beacon signal during at least a second portion of the first assigned time slot or at least a portion of a second assigned time slot. A peer device may measure a time of arrival (TOA) for the beacon signal. When three or more TOAs are obtained from three or more peer devices, it may be possible to determine the location of the target mobile station. In accordance with further aspects, a PPT scheme may be enabled to discover, alert, and/or otherwise determine which peer devices may be geographically nearby a target mobile station and possibly available to support certain PPT operations.
摘要翻译：提供了用于无线网络中的对等定位操作的方法和装置。一种方法包括：通过无线通信链路从另一设备接收对等三边测量（PPT）请求消息，响应于所述第一分配时隙的至少第一部分，在至少第一PPT信标信号发送第一PPT信标信号 PPT请求消息，并且在第一分配时隙的至少第二部分或第二分配时隙的至少一部分期间选择性地发送至少第二PPT信标信号。对等设备可以测量信标信号的到达时间（TOA）。当从三个或更多个对等设备获得三个或更多个TOA时，可以确定目标移动站的位置。根据另外的方面，PPT方案可能能够发现，警告和/或以其他方式确定哪些对等设备可能在地理上在目标移动站附近，并且可能可用于支持某些PPT操作。
