Abstract:
Positioning determination of a communication device in a wireless communication network is supported by a positioning device receiving [ 230 ] tight synchronization signals from a master positioning cell; determining [ 232 ] therefrom a plurality of time differences between their actual and theoretical times of arrival; synchronizing [ 234 ] a positioning cell clock based on the received tight synchronization signals adjusted by the time differences; and emitting [ 236 ] to the communication device a positioning signal at a time determined by the synchronization. The positioning signal includes an identifier of the positioning cell, and it is transmitted so as not to interfere with positioning pilot signals transmitted by the wireless communication network. The positioning device may alternatively receive synchronization signals from another positioning cell instead of a master positioning cell.

Claim (Index 2):
The method of  claim 1  further comprising:\n receiving by the positioning cell positioning signals transmitted from two adjacent positioning cells in direct line-of-sight with the positioning cell; \n measuring by the positioning cell a drift error between the positioning signals of the two adjacent positioning cells, wherein the drift error is determined from a difference between estimated times of arrival of the positioning signals and theoretical times of flight of the positioning signals; and \n transmitting by the positioning cell the drift error to the adjacent positioning cells, whereby the adjacent positioning cells can use the drift error for calibration.
