Title
Resource optimization for cellular network assisted multichannel D2D communication
Abstract
Cellular network assisted device-to-device (D2D) communication can improve spectrum utilization by jointly coordinating cellular and D2D users. This paper studies D2D communication sharing multiple cellular channels and optimizes the overall system performance by maximizing the weighted sum rate (WSR) of the cellular and D2D users. We first provide an analytical characterization of the optimal resource sharing in the single channel case. Then, based on it, we propose a simple but efficient algorithm to maximize the WSR in the general multichannel case. Furthermore, we also propose two alternative algorithms to achieve better performance at a cost of higher complexity. In addition, a simple condition is provided to verify the global optimality of the obtained solution. Numerical results show that the proposed algorithms outperform the existing single-channel design, and interestingly the optimality condition is satisfied in many cases, thus justifying the merit of the proposed algorithms from both theoretical and practical aspects.
