Abstract
A method of generating a device-to-device (D2D) signal by a user equipment (UE) in a wireless communication system, the method includes mapping a sequence for an automatic gain control (AGC) preamble to a resource element; and generating the AGC preamble by performing an inverse fast Fourier transform (IFFT) on the sequence for the AGC preamble mapped to the resource element, further the sequence for the AGC preamble is repeated N times when mapped to the resource element, and also N is determined based on at least one of a system frequency bandwidth or a transmission frequency bandwidth.
