据预测，在今后十年，移动的通信量预计将比我们今天的通信量增加1，000倍。为了满足这种急剧的流量增长，与当前一代无线网络部署相比，下一代移动的网络也有望实现1,000倍的容量增长。在本文中，我们将讨论如何在十年的时间框架内实现这种容量增长。我们讨论的技术，我们希望有最高的机会增加系统容量，并估计其收益的基础上分析和仿真。我们观察到，容量增长的主要驱动力预计将来自网络架构的进步，异构网络和信息和通信技术的融合是两个关键技术。我们还估计，空中接口的演变将不仅集中在提高链路和系统的频谱效率，但也有利于所需的网络效率的提高。本文提供了对通信技术演进的见解，并可用作第五代（5G）技术发展的指导方针。
It has been projected that, in the next decade, a mobile traffic increase on the order of 1,000 times is expected compared to what we experience today. To meet that dramatic traffic growth, next-generation mobile networks are also expected to achieve a 1,000-fold capacity increase compared to the current generation of wireless network deployments. In this article, we discuss how such capacity growth could be achieved in a ten-year time frame. We discuss the techniques that we expect to have the highest opportunity for increasing the system capacity and estimate their gains based on analysis and simulation. We observe that the main driver of capacity growth is expected to come from network architecture advancements, with heterogeneous networks and convergence of information and communication technology being two of the key techniques. We also estimate that the air-interface evolution would focus not only on improving the link and system spectrum efficiency but also on facilitating the required network efficiency improvements. This article provides insights into the communication technology evolution and can be used as a guideline for technology development toward the fifth generation (5G).
