本文重点介绍构成未来 5G 网络的关键支持技术之一，即蜂窝基础设施底层的 Direct-LTE 通信，通常也称为设备到设备 (D2D)。针对D2D用户和蜂窝用户(CU)之间的通信提出了能量效率算法，并根据拉格朗日对偶理论，给出了D2D用户的最优功率和速率控制解决方案，同时满足与CU相关的干扰限制。最后，使用新算法实现D2D用户和CU之间的比例公平，并通过数值结果表明对CU的干扰可以限制在预定义的阈值之下。
This paper focuses on one of the key enabling technology that will compose future 5G network, the Direct-LTE communication underlying a cellular infrastructure, also commonly known as Device-to-Device (D2D). Energy efficiency algorithms are proposed for the communication between D2D users and cellular users (CUs) and, following the Lagrangian duality theory, an optimal power and rate control solution is given for D2D users, while satisfying the interference limits related to CUs. Finally, the new algorithm is used to achieve proportional fairness between D2D users and CUs and to show with numerical results that the interference to CUs can be limited to always be under a predefined threshold.
