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 disclosure relates to a pre-5th-Generation (5G) or 5G communication system rt to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An apparatus and method for acquiring synchronization information through the transmission and reception of signals between devices for device to device (D2D) communication is provided. A method for a user equipment (UE) in a wireless communication system includes detecting a synchronization signal of another UE in a predetermined measurement gap. The method also includes transmitting a detected result of the synchronization signal to an evolved Node B (eNB). A start time point of the measurement gap in a first measurement gap period and a star(time point of the measurement gap in a second measurement gap period are different from each other.

Abstract: A synchronization method and an apparatus for Device-to-Device (D2D) communication in a User Equipment (UE) are provided. The method includes comparing a reception power of a signal received from an evolved Node B (eNB) with a first reference power, if the reception power is less than the first reference power, generating and transmitting a synchronization signal for D2D communication by operating as a synchronization reference UE, comparing the reception power of a signal received from the eNB with a second reference power, and if the reception power is greater than or equal to the first reference power and less than the second reference power, relaying a synchronization signal received from the eNB by operating as a synchronization relaying UE.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data rates than a 4th generation (4G) communication system such as long term evolution (LTE). A method for positioning a user equipment (UE) in a wireless communication system includes receiving a reference signal (RS) in a first bandwidth from each of a plurality of anchor nodes scheduled for RS transmission by a network server, determining whether a path overlap has occurred between the UE and the anchor nodes based on symmetry of channel impulse responses of the received RSs, transmitting a bandwidth extension request message to the network server, upon occurrence of a path overlap, receiving an RS in a second bandwidth larger than the first bandwidth from each of the plurality of anchor nodes in response to the transmission of the bandwidth extension request message, and generating information required to position the UE, using the RSs received in the second bandwidth.

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting a device to device (D2D) discovery signal by a user equipment (UE) in a communication system supporting a D2D scheme is provided. The method includes determining transmission power for D2D discovery signal transmission, and transmitting a D2D discovery signal using the transmission power, wherein the transmission power is determined by considering a cell at which the D2D discovery signal is transmitted.
