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 1):
A method implemented by a positioning cell for supporting positioning determination of a communication device in a wireless communication network, the method comprising:\n receiving by the positioning cell from a master positioning cell a tight synchronization signal, wherein the positioning cell is in direct line-of-sight to the master positioning cell; determining by the positioning cell a time difference between time of arrival of the tight synchronization signal and theoretical time of arrival of the tight synchronization signal, where the theoretical time of arrival is corrected by theoretical time of flight along a direct line-of-sight path from the master positioning cell to the positioning cell; synchronizing the positioning cell based on the received tight synchronization signal adjusted by the time difference, wherein the synchronizing comprises synchronizing a clock in the positioning cell; emitting by the positioning cell to the communication device in the wireless communication network a positioning signal at a time determined by the synchronized clock; wherein the positioning signal comprises data indicative of an identifier of the positioning cell.
