Abstract:
The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An apparatus and method for measuring a distance between wireless devices using a first signal transmitted/received between the wireless devices in a wireless communication system are provided. The method includes: receiving the first signal for distance measurement transmitted from a first of the wireless devices; receiving a signal reflected by a reflector after being transmitted from the first of the wireless devices; and based on the received first signal and the received reflected signal, estimating a distance between the second of the wireless devices and the reflector.
