LTE-U与WiFi在非授权频段的共存方案研究
Study on coexistence schemes of LTE-U and WiFi on unlicensed bands
摘要
Abstract
The fast growth of mobile data has brought new challenges on the limited spectrum resource.To address this issues,the LTE-U is adopted as one of the promising solutions by global operators.As being one of the key technologies in Fifth-generation(5G) network,LTE-U could provide a higher transmission rate,spectrum efficiency as well as seamless mobile user experience by taking advantage of the Carrier Aggregation(CA) technology.In particular,the most critical issue of LTE-U is in coexistence with WiFi systems,due to the differences in radio access technology between these two systems.In this paper,we introduce the background and the key technologies of LTE-U,including the operating mode of LTE-U,the CA technology and the requirements in the system design.Furthermore,we point out the primary challenges in the coexistence between LTE-U and WiFi systems,and summarize the proposed coexistence schemes in literature.Finally,we discuss the possible research areas in the future.关键词
