The proliferation of smart devices has boosted the improvement of wireless network technologies. Herein, networking functions should be properly guaranteed even in highly dense environments in terms of service quality and data rate. In this paper, we present an efficient power allocation algorithm using non-orthogonal multiple access and smart array antennas to increase the capacity in highly overlapped multi-cell environments. We evaluate the proposed algorithm and compare with the conventional orthogonal multiple access scheme with smart antennas. Through intensive simulations and experiments at the system level for performance evaluations, it is confirmed that the proposed scheme obtains a drastic throughput gain up to 50% in the overlapped region of highly dense networks.

多小区波束成形网络中使用非正交多址接入的联合调度和功率分配

智能设备的普及推动了无线网络技术的进步。在此，就服务质量和数据速率而言，即使在高度密集的环境中也应适当地保证网络功能。在本文中，我们提出了一种有效的功率分配算法，该算法使用非正交多址访问和智能阵列天线来增加高度重叠的多小区环境中的容量。我们评估提出的算法，并与传统的智能天线正交多址方案进行比较。通过在系统级别进行密集的仿真和实验以评估性能，可以确认所提出的方案在高密度网络的重叠区域中获得了高达50％的大幅吞吐增益。
