    Abstract: A first terminal within a first cell of a first base station receives a synchronization signal and a synchronization channel that are broadcasted through a downlink by the first base station. The first terminal acquires synchronization for D2D communication using the synchronization signal and the synchronization channel. When the first terminal is connected to the first base station, in order to request allocation of a first resource for D2D communication, the first terminal transmits first information for D2D communication to the first base station through a first data channel for cellular communication. The first terminal receives D2D control information including information about the first resource that is allocated to the first terminal from the first base station. The first terminal broadcasts a second data channel for D2D communication using the D2D control information.

    Abstract: There are provided a method of a device-to-device (D2D) discovery and an apparatus thereof. The method of the device-to-device discovery performed in a terminal may includes registering a discovery service of the terminal using service information on a service provided from an user; transmitting a discovery transmission activation request to a network in which the terminal is located; receiving a response in response to the discovery transmission activation request from the network; and transmitting a discovery message when the response is an approval message.

    Abstract: A technology enabling a terminal to receive acknowledgement (ACK)/negative ACK (NACK) information about data transmitted from the terminal is provided. The method includes receiving cyclic shift information for a reference signal from the base station; transmitting, to the base station, the data and a reference signal which is cyclic-shifted using a cyclic shift value, the cyclic shift value being determined based on a dynamic cyclic shift value mapped one-to-one to the cyclic shift information for the reference signal; and receiving, from the base station, the ACK/NACK information about the transmitted data through a radio resource of a downlink channel, the radio resource of the downlink channel being identified based on a modifier mapped one-to-one to the cyclic shift information for the reference signal.

    Abstract: A dynamic channel assignment method includes receiving, at a ground control station (GCS), assignment of a first communication channel set from a spectrum authority before takeoff of the unmanned aircraft; receiving, at the GCS, assignment of a second communication channel set when the unmanned aircraft is to move from a first area using the first communication channel set to a second area using the second communication channel set due to a flight plan of the unmanned aircraft after takeoff of the unmanned aircraft; and after the unmanned aircraft enters the second area, maintaining, at the GCS, the first communication channel set when the unmanned aircraft reenters the first area due to the flight plan, and returning, at the GCS, the first communication channel set to the spectrum authority when the unmanned aircraft does not reenter the first area due to the flight plan.
