Abstract
Methods and apparatus related to determining location of one or more mobile devices based on signals received by mobile device and signals received by fixed devices such as access points (APs) in a communications system are described. In accordance with various embodiments, mobile devices, e.g., peer devices, measure one or more signal characteristics, e.g., received signal power level, of signals received from peer devices and report this information along with information identifying the peer devices to which individual signal measurements correspond. The time of the signal measurements is also reported allowing a location determination server to time align signal measurements made by multiple different devices, e.g., mobile devices and access points, and use signals measurements from the multiple devices to determine the location of one or mobile devices, e.g., at one or more points in time, with more accuracy than if AP signal measurement alone were used.
