Terminal and distance estimation method thereof
First Claim
1. A terminal operating in a wireless communication system supporting device-to-device (D2D) communication, the terminal comprising:
- a transceiver; and
at least one processor configured to;
synchronize the terminal with other terminals,control the transceiver to transmit a first time information registration request including identity information of the terminal and a transmission time of a discovery message to a server and receive a first time information registration response including time-related information from the server,control the transceiver to transmit the discovery message including the time-related information to the other terminals, andcontrol the transceiver to receive distance information from at least one of the other terminals, the distance information being calculated based on the time-related information and a reception time of the discovery message.

Abstract
A terminal and a distance estimation method thereof for use in a wireless communication system supporting device-to-device (D2D) communication are provided. The terminal includes a transceiver configured to communicate with other terminals and at least one processor configured to control the transceiver to transmit a discovery message including time information to the other terminals and receive distance information calculated by the other terminals, the distance information being calculated based on the time information. The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system, such as Long Term Evolution (LTE).
