    Abstract: A method for a first terminal communicating with a base station to perform direct communication with a second terminal is provided. The first terminal determines first timing for transmitting or receiving a first signal to or from the base station. Next, the first terminal determines second timing for transmitting a second signal for terminal discovery to the second terminal. When the first timing and the second timing overlap, the first terminal then changes either the first timing or the second timing.

    Abstract: A communication method of a terminal and a communication method of a base station for a direct communication link between terminals are disclosed. A base station schedules a reference terminal to transmit a ranging code, and schedules target terminals to receive the ranging code. The reference terminal measures the ranging code received from the target terminals, and transmits a ranging code measurement result to the base station. The base station selects a terminal from among the target terminals to form the direct communication link with the reference terminal among the target terminals based on the ranging code measurement result.

    Abstract: Disclosed is a method of identifying location information of a signal source, the method including: identifying, at a first position, first position information and first posture information of an UAV equipped with a linear array antenna; identifying, after identifying a first measured azimuth between the signal source and the antenna at the first position, a first corrected azimuth; identifying, at at least one second position, at least one piece of second position information and at least one of second posture information of the UAV; identifying, after identifying at least one second measured azimuth between the signal source and the antenna at the at least one second position, at least one second corrected azimuth; and estimating the location information of the signal source by using the first position information, the first posture information, the first corrected azimuth, the second position information, the second posture information, and the second corrected azimuth.
