摘要翻译:
我们提出了新的资源分配算法,其目标是在无线网络资源重用和干扰避免之间找到一个良好的折衷。为此,我们首先研究了网络单元可用资源预算与最优效用以及通过求解最大最小效用优化问题得到的最优资源效率之间的函数性质。根据这些函数的渐近性态,我们得到了一个过渡点,它指示在给定的资源预算下,网络是运行在有效的噪声限制区域还是运行在无效的干扰限制区域。针对运行在低效率状态下的网络,提出了一种新的部分资源静音方案,以提高网络的资源利用效率。框架很笼统。它不仅可以应用于4G网络的下行链路,还可以应用于配备灵活双工机制的5G网络。数值结果表明,与全频率复用的最大最小效用优化问题相比,该方案的性能有显著提高。

英文摘要:
We propose novel resource allocation algorithms that have the objective of finding a good tradeoff between resource reuse and interference avoidance in wireless networks. To this end, we first study properties of functions that relate the resource budget available to network elements to the optimal utility and to the optimal resource efficiency obtained by solving max-min utility optimization problems. From the asymptotic behavior of these functions, we obtain a transition point that indicates whether a network is operating in an efficient noise-limited regime or in an inefficient interference-limited regime for a given resource budget. For networks operating in the inefficient regime, we propose a novel partial resource muting scheme to improve the efficiency of the resource utilization. The framework is very general. It can be applied not only to the downlink of 4G networks, but also to 5G networks equipped with flexible duplex mechanisms. Numerical results show significant performance gains of the proposed scheme compared to the solution to the max-min utility optimization problem with full frequency reuse.
