LTE和Wi-Fi系统间灵活频谱使用关键技术

摘要

针对授权辅助接入，提出了一种适用于LTE-U与Wi-Fi共同使用免授权频段的方法，该方法无需更改Wi-Fi协议就能实现LTE-U与Wi-Fi比例公平使用免授权频谱，有效聚合授权频谱与免授权频谱，提升频谱效率，为用户提供更好的业务体验。%In this paper, we propose a method for realizing the coexistence of LTE-U and Wi-Fi systems in unlicensed bands. This method is based on the Licensed Assisted Access scheme. With our proposed method, LTE-U and Wi-Fi systems can jointly use the unlicensed spectrum in a proportional and fair way, without changing the Wi-Fi protocol. Therefore, our method can aggregate licensed and unlicensed spectrum resources, improve spectrum efficiency, and provide better user experience.
