Coexistence of Wi-Fi and Cellular With Listen-Before-Talk in Unlicensed Spectrum
Abstract—In this letter, we analyze the coexistence performance of Wi-Fi and cellular networks with different ListenBefore-Talk (LBT) procedures in the unlicensed spectrum. For this analysis, the behavior of a cellular base station is modeled as a Markov chain that is combined with Bianchi’s Markov model depicting the behavior of a Wi-Fi access point. The proposed mathematical framework finds the optimal contention window size of cellular base stations, which maximizes the total throughput of both networks while satisfying the required throughput of each network. Numerical results show the validity of adjustment in the parameter of LBT.
