摘要: The present invention relates to 5G or pre-5G communication system for supporting a higher data transmission rate after 4G communication system such as LTE. The present invention provides a method and a device for executing a hybrid automatic repeat request (HARQ) through a channel in an unlicensed frequency band. More particularly, a method for executing a HARQ through a channel in an unlicensed frequency band in a terminal of a communication system comprises the procedures of: requesting uplink scheduling; if a first uplink (UL) grant with respect to the scheduling request is received, sensing whether or not a channel is clear; transmitting first uplink data on the basis of whether or not the channel is clear; if negative acknowledge (NACK) with respect to the first uplink grant and a second uplink grant are received, sensing whether or not the channel is clear; and transmitting second uplink data and an indicator, which indicates whether or not the second uplink data transmission is a retransmission, on the basis of whether or not the channel is clear, wherein the indicator, which indicates for retransmission, is determined on the basis of a reference signal (RS) detection failure indicator, of a base station, which is transmitted from the base station together with the second uplink grant.

摘要: The present invention provides a method for providing a service to a device having an interest in a specific service in a device-to-device (D2D) condition. The method includes: searching for a device which enters into an area managed by a device which provides the specific service; and identifying an interest of the searched device in the specific service and inviting the searched device to participate in the specific service. In the method, by selectively connecting a session based on a service interest, an efficient management in view of an entire network capacity is possible and an advantage of reducing a time for session connection is achieved.

摘要: The present invention relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate than that of a 4G system and subsequent systems, and a system thereof. The present invention can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety related services and the like). The present invention provides a method and a device for transmitting a synchronization signal for device-to-device (D2D) communication. According to the present invention, a first terminal receives a D2D synchronization signal (D2DSS) and a physical D2D synchronization channel (PD2DSCH) corresponding to the D2DSS from a second terminal, and transmits the D2DSS to the second terminal according to a method preassigned with the second terminal so as to indicate that the first terminal has successfully received the D2DSS or the PD2DSCH.
