To initiate Device to Device (D2D) communication, proximal device discovery is the most important problem in the contemporary cellular networks. By using reference signal (RS), devices can be discovered for a D2D companion through the proximal discovery process. We propose an RS model for proximal device discovery and discovery resources multiplexing using Zadoff–Chu (ZC) sequence for RS transmission and detection. The proposed proximal device discovery model is robust for collision avoidance, and provides rapid and accurate discovery in a dense area. The performance of proposed discovery procedure is verified numerically and by simulation. Random search and the smart random search algorithms are applied for evaluation of proposed model in terms of discovery time and discovered devices.
