Licensed-Assisted Access (LAA) is a promising technology to address the issues of ever-increasing traffic demands in cellular systems. However, the efficient coexistence of Wi-Fi and LAA in the same unlicensed spectrum raises many challenges. Most of the studies addressing this coexistence issue focus on a coexistent LAA and Wi-Fi network sharing a single carrier. In this paper, we investigate a coexistent network with multiple available carriers, which is the case for practical deployments. Specifically, we develop an efficient adaptive energy detection algorithm to avoid frequent collisions in coexistent Wi-Fi and LAA networks. moreover, a carrier selection algorithm, based on the LAA energy detection threshold, is proposed to further improve the coexistence performance. Simulation results validate the effectiveness of the proposed adaptive energy detection and carrier selection schemes.
