Abstract
With the widespread deployment of wireless technologies and IoT, 5G wireless networks will support various communication connectivity and services for the huge number of wireless smart/ intelligent devices and machines. The challenge lies in assisting wireless networks to intelligently learn experience, autonomously optimize network configurations and smartly make decisions to support massive wireless smart devices with minimum human intervention, so the diverse and colorful service requirements can be satisfied with the optimum performance. Machine learning, as one of the powerful artificial intelligence tools, is capable of efficiently supporting wireless smart devices by assisting them to smartly observe the environment, analyze data and make decisions with the intelligence. Hence, in this article, we briefly review the major concepts of common machine learning techniques and present their potential applications in intelligent wireless networks, including spectrum sensing, channel estimation, device clustering, behavior prediction, position tracking, data demission reduction, adaptive routing, energy harvesting/efficiency, resource management, and so on. Furthermore, we propose deep reinforcement learning for intelligent resource management in intelligent wireless networks in an exemplary case study. Simulation results demonstrate the effectiveness and advance of machine learning in intelligent wireless networks.
