To fully utilize its advantage, an efficient algorithm for scheduling multiple subbands while taking into account practical requirements such as probabilistic QoS and aligned transmission constraints is needed. In this paper, we apply a probabilistic method to relax the constraints and decouple the optimal scheduling problem into two sub-problems, namely user assignment and power allocation. We solve each sub-problem by using parametric and iterative algorithms. Simulation results show that the proposed method outperforms the baseline. ? 2020 IEEE.5G mobile communication systems; Scheduling; High spectral efficiency; Iterative algorithm; Multiple access; Optimal scheduling; Power allocations; Practical requirements; Probabilistic methods; Transmission constraint; Iterative methodsconference paper10.1109/ICCWorkshops49005.2020.91452812-s2.0-85090266589
