Abstract: A communication method of a terminal and a communication method of a base station for a direct communication link between terminals are disclosed. A base station schedules a reference terminal to transmit a ranging code, and schedules target terminals to receive the ranging code. The reference terminal measures the ranging code received from the target terminals, and transmits a ranging code measurement result to the base station. The base station selects a terminal from among the target terminals to form the direct communication link with the reference terminal among the target terminals based on the ranging code measurement result.

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: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:
The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.-

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.
