    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 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 start time point of the measurement gap in a second measurement gap period are different from each other.

    Abstract: The present invention is to provide a method and device for controlling transmission power by taking comprehensive consideration not only of the effect received onto itself in each device-to-device (D2D) link of a D2D communication network but also of the effect exerted onto the neighboring links. According to an embodiment of the present invention, a processing method in a transmission terminal of a first link for controlling the transmission power of the transmission terminals of links in a D2D communication network, which includes terminals of at least the first link and terminals of a second link adjacent to the first link includes: measuring the strengths of first detection signals transmitted from reception terminals of the first link and the second link; and determining a first transmission power adjustment ratio for the transmission terminal of the first link so that a signal-to-interference ratio of the second link is greater than or equal to a predetermined threshold value on the basis of the measured strengths of the first detection signals.

    Abstract: In order to generate multiple-access signals, each transmitter transmits information by using all or a part of channel resources. The signal of each transmitter is mapped to an OFDM time-frequency resource space as a trellis modulation path. A mobile communication system maps trellis modulation paths of a plurality of transmitters to the same resource space. In order to effectively detect and distinguish signals of a plurality of transmitters transmitted through the same channel resource space, a receiver uses a message passing method between symbols and a path connection method. The receiver uses a state space expansion method, a backward pre-decoding method, and a successive interference cancellation method to more efficiently reconstruct a discovery signal.
