A Long Term Evolution Advanced (LTE-A) downlink scheduler must guarantee the Quality of Service (QoS) provisioning. Existing schedulers consider the Channel Quality Indicator (CQI) reports to determine their priority rules. Nevertheless, these reports may not be sufficiently accurate. In addition, existing scheduling policies fail to provide a good tradeoff(More)
In a previous proposal, we propose a scheduler that enhances the usage of the radio blocks (RBs). This paper consists of an extension of our previous scheme in order to find a good trade-off between both the delay and the PLR. The proposition consists of a scheduler based on the packet prediction mechanism (PPM). This scheduler provides the exact time at(More)
A good scheduler must respect requirements fixed by the 3GPP. Spectral efficiency may be assured by assigning each RB to the user that is predictable to exploit it at the best. The spectral efficiency guarantee may maximize the cell capacity. Similarly, assuring others requirements, which are fairness, computational complexity, cell-edge coverage, QoS(More)
In this paper, we study the LTE-A (Long Term Evolution Advanced) downlink scheduling. Delay aware schedulers are among the popular schedulers presented in the literature. These schedulers are based on fix and exact delay budget. Nevertheless, wireless channels are quickly modified which make fix delays not effective. Several contributions, based on fuzzy(More)
