Abstract

Spectrum sharing is a highly-efficient method to solve the problem of the exponential capacity demand increase in wireless communication. Long Term Evolution(LTE) and Wi-Fi are two of the most remarkable wireless technologies nowadays. And it is of great importance to research on the coexistence of the two technologies. When the interference level goes below a certain threshold, the channel is accessible to communication nodes while operating Wi-Fi network. As a result, it exerts significant influence on Wi-Fi operation with LTE coexisting. The work introduces some schemes in order to realize LTE/Wi-Fi coexistence. As demonstrated in the test results, the spectral efficiency of LTE is higher than that of Wi-Fi in unlicensed band. Therefore, it is reasonable for LTE to compete for using unlicensed band. Simulation results show that there is a significant increase in the cell throughput and the communication rate of users by aggregating licensed band and unlicensed band in LTE network. Meanwhile, it turns out to be a slight lower performance of Wi-Fi. The range of the performance degradation of Wi-Fi is narrower than that of the performance promotion of LTE, thus achieving the performance promotion of overall system.
