Abstract

In a direct communication between terminals, a terminal transmits a synchronization channel preamble part after transmitting a synchronization channel message part including synchronization information. The terminal receives a dedicated channel including a direct communication packet after transmitting the synchronization channel preamble part. A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.
