摘　　要：随着通信技术的发展,无线通信业务量呈现爆发式增长,如何进一步提升传输速率和网络容量成为亟待解决的问题。当前利用物理层技术提高频率效率,对未来的需求来说微不足道,如何有效利用授权频带以外的带宽资源成了通信研究的重要方向[1-3]。本文将对非授权频带频谱共享技术的原理和发展进行介绍,并针对MulteFire技术的专利申请进行分析。With the development of communication technology,the amount of wireless communication traffic has exploded,and how to further increase the transmission rate and network capacity has become an urgent problem to be solved. At present,the use of physical layer technology to improve frequency efficiency is insignificant for future needs. How to effectively utilize bandwidth resources outside the licensed band has become an important direction of communication research[1-3]. This article will introduce the principle and development of unlicensed band spectrum sharing technology and analyze the patent application of MulteFire technology.
