Abstract:
1. A method of synchronizing a target base station with a mobile station in a wireless communications system, comprising: calculating, by an element on the network side, a propagation delay between the target base station and the mobile station at least partially based on a first measured chip offset between a downlink channel of a serving base station and a pilot signal of the target base station, the downlink channel being between the serving base station and the mobile station, wherein the calculating step calculates the calculated propagation delay based on (i) the first chip offset between the downlink channel and the pilot channel of the target base station and (ii) a second chip offset between an uplink channel of the mobile station and the pilot channel of the target base station; and sending, by the element on the network side, the calculated propagation delay to the target base station.
