Abstract
The Licensed-Assisted Access (LAA) is a novel technology to extend the usable spectrum for Long Term Evolution (LTE). In recent years, there has been dramatic increase in researches on LAA. However, the issue of performance analyses on the heterogeneous network which includes asynchronized multiple LAA networks and Wi-Fi networks remains open. Hence, this paper mainly focuses on the throughput performance of such heterogeneous networks in a saturated scenario.We first model the random backoff procedures of LAA networks and Wi-Fi network into two-dimensional Markov chains. Based on these models, we analyze the throughput performance in the heterogeneous superframe framework which is abstracted from the channel access behaviors of the LAA networks and Wi-Fi networks. The correctness of the analytical results have been verified by sufficient Monte Carlo simulations.
