Abstract: Disclosed is a method for transmitting a discovery signal in device-to-device communication. In phase 1, for devices at a long range, a discovery signal is transmitted by dividing a band like in OFDMA, and in phase 2, for devices at a short range, the discovery signal is transmitted by using a full band.

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 technology enabling a base station to transmit acknowledgement (ACK)/negative ACK (NACK) information about data received from a terminal is provided. A cyclic shift value difference of each terminal may be maximized and a radio resource for transmitting the ACK/NACK information may be assigned without collision.

Abstract: A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.

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.
