Abstract: 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.

Abstract: 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.

Abstract: 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 for transmitting data on the basis of a measurement of a channel of an unlicensed band in a mobile communication system, the method comprising the procedures of: selecting a random number for backoff counting; determining whether to decrement the random number by 1; decrementing the random number by 1 on the basis of the determining; determining whether the channel is idle by measuring the channel; completing the backoff counting if the random number becomes 0; and transmitting data by means of the channel if the backoff counting is completed.

Abstract: A method for acquiring a service category table required for finding a service includes acquiring information on a latest service category table by identifying version information of a service category table from a broadcasting signal received from adjacent devices during a process of searching for a device supporting a service desired among devices, and acquiring a service category table of a latest version by establishing a session connection with a device supporting the service category table of the latest version based on the information. By acquiring the information on the latest service category table, a session connection with only the device providing the desired service is established so that an optimized session connection establishing process can be performed and a total network capacity can be efficiently managed. Also, the latest service category table can be acquired from the session-connected device, and thus a new service can be easily identified.

Abstract: Disclosed is a method for supporting synchronization of a user equipment (UE) for D2D communication. The method includes: first scanning for checking a synchronization signal transmitted from a nearby UE; establishing the UE as a synchronization-transmitting UE, based on a result of the first scanning; transmitting a synchronization channel including timer value information indicating scanning time at which a scanning starts; and second scanning based on the timer value information.

Abstract: A method and apparatus for performing a state transition for Device to Device (D2D) communication are provided. The method includes determining whether D2D initiation is required, while a terminal is operating in a first or a second state defined by EPS (Enhanced Packet System) Mobility Management (EMM)-Deregistered and EPS Connection Management (ECM)-IDLE at a Non-Access Stratum (NAS) layer and Radio Resource Control (RRC)-IDLE. If the D2D initiation is required, the method includes transitioning to a third state defined by EMM-Registered and ECM/RRC-Connected and performing the D2D initiation through a mobile communication network. If a deactivation condition is satisfied or a D2D state update is completed in the third state, the method includes transitioning to a fourth state defined by EMM-Registered and ECM/RRC-IDLE, and if a state update or scheduling for D2D communication is required in the fourth state, the method includes transitioning to the third state.
