Abstract

Long Term Evolution (LTE) in unlicensed bands (U-LTE) has emerged as a promising solution to address the growth of mobile data traffic. U-LTE extends the benefits of LTE with unused portions of the unlicensed 5 GHz spectrum, which is primarily used by Wi-Fi users. However, uncertainty about the availability of bandwidth makes the adoption of U-LTE a challenging new task for operators. In this work, we propose a stochastic programming approach for the allocation of U-LTE resources to expand bandwidth and coverage while controlling the risk of conflict with Wi-Fi demand. Three models from the literature for this demand are used in our computational experiments. The results show the importance of prior knowledge about the distribution of Wi-Fi demand.
