Abstract
This paper mainly studies the coexistence mechanism of running LTE and Wi-Fi system simultaneously in the unlicensed frequency bands and achieves the system-level simulation. The simulation results show that LAA can be in harmony with Wi-Fi in the unlicensed bands. To design a reasonable retreat mechanism on LAA system
can simultaneously improve the throughput of LAA and Wi-Fi system
and also improve resource allocation fairness and efficiency.
