Title: Method for transmitting uplink signal for location-based service and user device, and method for measuring location of user device using uplink signal and base station

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.
