摘要

在毫米波(mmWave)通信中,多连接可以增强通信容量,同时以增加功耗为代价。在本文中,我们研究了一种基于深度展开的联合用户关联和功率分配方法,以最大限度地提高具有多连通性的毫米波网络的能量效率。该问题被表述为一个混合整数非线性分式优化问题。首先,我们开发了一个三阶段迭代算法来实现原始问题的上界。然后,我们用基于卷积神经网络(CNN)的加速器和可训练参数展开迭代算法。此外,我们还提出了一种CNN辅助的贪婪算法来获得可行的解。仿真结果表明,该算法具有良好的性能和较强的鲁棒性,但计算复杂度大大降低。

Deep unfolding for energy-efficient resource allocation in mmWave networks with multi-connectivity

In millimeter-wave (mmWave) communications, multi-connectivity can enhance the communication capacity while at the cost of increased power consumption. In this paper, we investigate a deep-unfolding-based approach for joint user association and power allocation to maximize the energy efficiency of mmWave networks with multi-connectivity. The problem is formulated as a mixed integer nonlinear fractional optimization problem. First, we develop a three-stage iterative algorithm to achieve an upper bound of the original problem. Then, we unfold the iterative algorithm with a convolutional neural network (CNN)-based accelerator and trainable parameters. Moreover, we propose a CNN-aided greedy algorithm to obtain a feasible solution. The simulation results show that the proposed algorithm can achieve good performance and strong robustness but with much reduced computational complexity.

期刊介绍: Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
