Abstract: A link scheduling method in a system for performing Device-to-Device (D2D) communication includes periodically collecting information indicating whether to perform a medium access from at least one neighboring link determining at least one link expected to perform a medium access in a corresponding traffic slot among links with a higher priority than the terminal based on the collected information, and determining whether to perform the medium access of the terminal by considering only the at least one link expected to perform the medium access.

Abstract: A Synchronization Channel (SCH) transmission method includes generating a Primary SCH (P-SCH) sequence according to supplementary information. The supplementary information includes at least one of Base Station (BS) type information, Fast Fourier Transform (FFT) size information, BandWidth (BW) information, group information, sector information, and carrier type information. The method also includes modulating the P-SCH sequence and mapping the modulated P-SCH sequence to subcarriers within a predefined subcarrier set. The subcarriers are included in the subcarrier set being spaced one subcarrier interval apart. The method further includes generating a P-SCH symbol by Orthogonal Frequency Division Multiplexing (OFDM)-modulating the P-SCH sequence mapped to the subcarriers, and transmitting the P-SCH symbol.
