Abstract
A user equipment (UE), a device to device (D2D) UE, a backhaul device and a positioning method thereof are provided. The D2D UE measures an uplink reference signal transmitted from the UE and generates an uplink measurement report message according to the measured uplink reference signal. The backhaul device receives the uplink measurement report message and determines location information on at least one of the UE and D2D UE based on the uplink measurement report message.
