Abstract: A synchronization method by a device is provided in a device-to-device direct communication. The device receives synchronization signals from a plurality of other devices at a current frame, and estimates a synchronization time at a next frame based on the synchronization signals received from the other devices.

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: Disclosed herein are a cooperation MIMO transmitting/receiving method and a terminal for supporting the same. A master terminal forms a slave terminal and a cluster performing cooperation communication. The master terminal transmits some data of data to be transmitted to a slave terminal and shares the some data with the slave terminal, and the slave terminal transparently transmits data transmitted from the master terminal to a target node.

Abstract: A D2D direct communication method is provided. The device sets at least one frame among a plurality of frames included in a superframe to a frame type 0 which is sectionized into a synchronization region for performing a synchronization procedure, a discovery region for discovering devices, a peering region for a connection, and a data region for scheduling of resources and data transmission. The device sets remaining frames among the plurality of frames to a frame type 1 which is sectionized into the synchronization region and the data region.
