Abstract: An operation method of a terminal includes receiving configuration information from a serving base station; measuring channel states of the serving base station and a target base station; when a difference between received signal strengths of the serving base station and the target base station is not less than a handover preparation offset, determining that a handover preparation event has occurred and transmitting a measurement report message to the serving base station; and when the difference is equal to or greater than a handover execution offset, determining that a handover execution event has occurred and transmitting a handover indication message informing of execution of a handover to the target base station. The channel state is normal state, abnormal state, or RLF state, and the configuration information indicates a different handover preparation offset and a different handover execution event according to the channel state.

Abstract: A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.

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.

Abstract: Disclosed are a method and a device for low latency communication in a communication system. An operation method of a base station comprises the steps of: transmitting first scheduling information of data units, transmitted through A sections in subframe #n, to a terminal through a first control channel in subframe #n; transmitting the data units to the terminal through the A sections; and transmitting second scheduling information of data unit(s), transmitted through B section(s) in subframe #(n+k) following subframe #n, to the terminal through a second control channel in subframe #(n+k). Therefore, the performance of the communication system can be improved.
