Timed fingerprint locating at user equipment
Abstract:
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 local bin grid framework mapping an area of a wireless network to stored differential values for each frame of the local bin grid framework for pairs of relevant NodeB radios. A timing offset can be determined, such that when a time value from the UE is accessed, the location can be quickly determined with minimal real time computation. In an aspect, the UE time value can be searched for in the pre-computed differential value data set indexed by a relevant NodeB radio pair to return a set of frames that can be intersected with a second set of frames for a second NodeB radio pair for the UE. The intersecting frames can represent the location of the UE in the wireless network.
