LTE使用未授权频段的方法研究
RESEARCH ON LTE USING UNLICENSED FREQUENCY BAND
摘要
Abstract
The introduction of LTE technology into the unlicensed band is one of the methods to solve the spectrum resource constraints of cellular systems.Describe the coexistence challenges that LTE introduces into unlicensed bands.In this paper, an enhanced FBE (E-FBE) structure is proposed for the LTE with FBE structure in LBT strategy to achieve the coexistence of fewer interception channel opportunities and fixed listening position.The structure introduces a random backoff procedure that allows LTE to listen for channels more flexibly based on the channel state.The simulation results show that, when WIFI and LTE coexist, this structure can solve the problem of LTE suppressed throughput and realize harmonious coexistence.关键词
