Abstract:
1. A method, comprising: receiving, by a first mobile device comprising a processor, timing offset information for a base station device pair of devices comprising a first base station device and a second base station device, wherein the timing offset information is relative to a second mobile device based on a difference between first measured timing difference information and computed timing difference information, the first measured timing difference information is based on a measured propagation time between the devices of the base station device pair and the second mobile device, and the computed timing difference information is based on a geometrically determined time between a determined location of the second mobile device, a determined location of the first base station device, and determined location of the second base station device; receiving, by the first mobile device, second measured timing difference information based on a measured propagation time between the devices of the base station device pair and the first mobile device; and determining, by the first mobile device, a location of the first mobile device based on the timing offset information for the base station device pair and the second measured timing difference information.
