Resumo
LTE (Long Term Evolution) in unlicensed band (LTE-U) has emerged as a promising solution to the
problem of the huge growth in mobile data traffic. It expands the benefits of LTE with bands of the
unlicensed 5 GHz spectrum, mainly used in IEEE 802.11. But uncertainties as to the availability of these
bands make the adoption of LTE-U a great challenge. In this dissertation, we propose a mixed linear
programming approach for allocating resources in order to expand service by LTE-U. Subsequently, we
propose a stochastic programming approach, taking into account the randomness of the unlicensed band,
allocating resources under a certain control in the risk of conflict with IEEE-802.11. We used three models
of the literature for the demand for IEEE 802.11 in our tests. The results highlight the importance of prior
knowledge about the distribution of this demand.
