摘要

云无线接入网（cloud radio access network

C-RAN）被认为是有望解决第五代移动通信（5G）技术服务需求问题的核心技术方案之一，已有研究表明C-RAN具有显著的技术优势，能有效提升网络的谱效率和能效率。总结了C-RAN的研究现状，给出了其系统架构和核心关键技术挑战，并讨论了C-RAN架构相比传统方案具有的优势和性能提升。

Abstract

Cloud radio access network（C-RAN）has been proposed as one of the most promising solutions to meet the service requirements of the fifth generation（5G）wireless communication systems. The published achievements indicate that C-RAN has many advantages

which can improve the spectrum efficiency and energy efficiency simultaneously. The state-of-the-art research achievements

system architecture and key technology challenges in C-RAN were studied. Furthermore

the performance gains over the traditional systems were introduced as well.
