As the emergence of new wireless applications, data traffic in cellular networks has dramatically increased in recent years, which imposes an immediate requirement for large network capacity. Device-to-device (D2D) communication is recently proposed as a novel and promising solution for increasing network capacity. This talk first tackles the D2D communication from a perspective on economic issues. In particular, we propose a truthful double auction for D2D communications in multi-cell cellular networks for trading resources in frequency-time domain, where cellular users with D2D communication capability act as sellers, and other users waiting to access the network act as buyers. With a sophisticated seller-buyer matching, winner determination and pricing, our design guarantees individual rationality, budget balance, and truthfulness. In the talk we also propose a promising concept of cooperative D2D communication to improve resource utilization in cellular networks. Based on a novel fine-grained resource allocation scheme, we jointly study relay assignment, transmission scheduling, and channel allocation. Finally, some future direction will be discussed.
