Patent ID: 10396883

Abstract:
Disclosed are techniques for positioning a user equipment (UE). In an aspect, a location server receives a first propagation time measurement and a first plurality of OTDOA RSTD measurements from a first UE at a first time, receives a second propagation time measurement and a second plurality of OTDOA RSTD measurements from a second UE at a second time, determines at least one real-time difference between a pair of base stations based on the first and second propagation time measurements and the first and second pluralities of OTDOA RSTD measurements, wherein the pair of base stations is associated with the first and second pluralities of OTDOA RSTD measurements, receives a third plurality of OTDOA RSTD measurements from a third UE at a third time, and determines a position of the third UE based at least in part on the at least one real-time difference between the pair of base stations.
