第四代无线通信系统已经或即将在许多国家部署。然而，随着无线移动设备和服务的爆炸性增长，仍然存在一些即使是4G也无法应对的挑战，如频谱危机和高能耗。无线系统设计者一直面临着新的无线应用对高数据速率和移动性的不断增长的需求，因此已经开始研究预计将在2020年后部署的第五代无线系统。在本文中，我们提出了一种分离室内和室外场景的潜在蜂窝架构，并讨论了5G无线通信系统的各种有前途的技术，如大规模MIMO、节能通信、认知无线电网络和可见光通信。文中还讨论了这些潜在技术面临的未来挑战。
The fourth generation wireless communication systems have been deployed or are soon to be deployed in many countries. However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Wireless system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In this article, we propose a potential cellular architecture that separates indoor and outdoor scenarios, and discuss various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communications, cognitive radio networks, and visible light communications. Future challenges facing these potential technologies are also discussed.
