摘要:

5G网络提供更大的带宽和更复杂的控制,以增强用户体验,同时与以前的移动网络相比,还需要更准确的通信信道估计。在本文中,我们提出了一种信道质量指示符(CQI)预测方法中的深度学习的方法,长短期记忆(LSTM)算法。针对5G新无线电(NR)系统中的下行链路调度,引入在线训练模块,以减少过时的CQI对通信降级的负面影响,特别是在高速移动性场景中。首先,我们分析了过时CQI在5G NR系统的下行链路调度中的影响。然后,我们设计了一个数据生成和在线训练模块来评估我们的预测方法在ns-3。仿真结果表明,所提出的LSTM方法优于前馈神经网络(FNN)方法,提高下行传输的系统性能。我们的研究可以为设计新的深度学习算法以提高5G NR系统的网络性能提供见解。

英文摘要:

5G networks provide more bandwidth and more complex control to enhance user's experiences, while also requiring a more accurate estimation of the communication channels compared with previous mobile networks. In this paper, we propose a channel quality indicator (CQI) prediction method in a deep learning approach in that a Long Short-Term Memory (LSTM) algorithm. An online training module is introduced for the downlink scheduling in the 5G New Radio (NR) system, to reduce the negative impact of outdated CQI for communication degradation, especially in high-speed mobility scenarios. First, we analyze the impact of outdated CQI in the downlink scheduling of the 5G NR system. Then, we design a data generation and online training module to evaluate our prediction method in ns-3. The simulation results show that the proposed LSTM method outperforms the Feedforward Neural Networks (FNN) method on improving the system performance of the downlink transmission. Our study may provide insights into designing new deep learning algorithms to enhance the network performance of the 5G NR system.
