使用蜂窝网络下的设备到设备（D2D）通信是提高小区容量和资源利用率的有效方式。当D2D链路被允许与传统蜂窝链路共享相同的物理资源时，有效的准入控制（AC）和无线电资源分配（RRA）策略在控制同信道干扰和提供QoS支持方面起着关键作用。在本文中，我们提出了一种新的联合AC和RRA策略，提供长期的蜂窝和D2D通信的QoS支持。AC算法导出蜂窝和D2D链路的最佳集合，以便在QoS和资源约束下最大化总收益。然后，给定的一组接纳的链路，低复杂度的短期RRA最大化的平均加权和速率QoS约束下。数值结果表明，该策略增加了满意的通信链路的数量高达50%，相比其他国家的最先进的框架。
The use of Device-to-Device (D2D) communications underlaying a cellular network is an efficient way to improve cell capacity and resource utilization. When the D2D links are allowed to share the same physical resources with traditional cellular links, efficient admission control (AC) and radio resource allocation (RRA) strategies play a key-role to control the co-channel interference and to provide QoS support. In this paper, we propose a novel joint AC and RRA strategy that provides QoS support in the long-term to cellular and D2D communications. The AC algorithm derives the best set of cellular and D2D links in order to maximize the total revenue under QoS and resource constraints. Then, given the set of admitted links, the low-complexity short-term RRA maximizes the average weighted sum-rate under QoS constraints. Numerical results show that the proposed strategy increases the number of satisfied communication links up to 50 %, compared to other state-of-the- art frameworks.
