M-ICT时代下的5G技术及创新

[摘要] 提出5G面临的3种技术发展挑战：增强型移动宽带（eMBB）、高可靠低时延通信（URLLC）、大规模机器通信（mMTC）。围绕5G的发展，中兴通讯创新性地提出统一空口（UAI）和云感知软网络（CAS）的技术理念，并围绕该理念，研发出一系列创新技术用于实现5G新型空中接口，例如滤波器组-正交频分多址(OFDMA FB-OFDMA)、多用户共享接入（MUSA)、大规模多输入多输出（MIMO）、统一帧结构（UFS）、平滑的虚拟小区（SVC）等，并基于软件定义网络（SDN）/网络功能虚拟化（NFV）技术构建出新型5G网络架构。这些技术和方案进一步地促进了5G的发展。

[Abstract] In this paper, three technical development challenges faced by 5G are proposed, including enhanced mobile broadband (eMBB), ultra reliable and low latency communication (URLLC), massive MTC (mMTC). ZTE Corporation proposes the technology concept: unified air interface (UAI) and cloud aware soft-network (CAS), and it also develops a series of innovative technologies for the realization of new 5G air interface, such as filter bank-orthogonal frequency division multiple access (FB-OFDMA), multi-user shared access (MUSA), massive multi input multi output (MIMO), unified frame structure (UFS), smooth virtual cell (SVC), and built a new 5G network architecture based on soft-defined network (SDN)/network function virtualization(NFV) technology. These technologies and schemes further promote the development of 5G.
