Abstract
A method performed by a first base station for positioning in a cellular communication system includes receiving, at the first base station, a signal transmitted by a second base station and estimating a Time of Arrival (TOA) of the received signal at the first base station according to a clock of the first base station. The method further includes determining a delta value that is a function of an amount of time between the TOA of the received signal at the first base station and a time reference at the first base station and performing either, (a) providing the delta value to a positioning estimation entity within the cellular communications system or (b) using the delta value at the first base station to reduce a time synchronization error between the first base station and the second base station, or (c) passing the delta value to a User Equipment (UE).
