Abstract:
In the present invention, an uplink synchronization signal for measuring a location of a user device is assigned to a predetermined uplink sub-frame and a predetermined sub-band and is transmitted to one or adjacent cells as well as a serving cell in a predetermined period. Since the synchronization signal for measuring the location is transmitted to a plurality of cells through the same wireless resource, other date are not transmitted to the same wireless resource and a near-far effect can be reduced in each cell.
