In 5G Millimeter-Wave (mmWave) networks, Base Station(BS) uses lots of narrow beams for coverage. Due to the limited ability of hardware, BS is only able to select a few beams for scheduling per slot. In outfield scenarios, the moving User Equipments (UEs) and different kinds of traffic lead to dynamic and uneven traffic distribution in beams. Traditional beam scheduling scheme selects beam with the UE scheduling priority and lacks consideration of the traffic distribution. Therefore, a smart beam scheduling scheme is required in mmWave networks to address the dynamicity and imbalance of network traffic. In this paper, a Real-Time Traffic Distribution (RTTD) scheme is proposed for beam scheduling in 5G mmWave networks. RTTD scheme takes the real-time UE and traffic distribution into account, selects the beams with the highest sum efficiency to maximize the throughput. In addition, to improve the fairness of scheduling for each UE, the proposed scheme considers the average throughput of all schedulable UEs. Compared with the traditional scheme that selects beams with the maximum UE scheduling priority, system level simulation results show that RTTD scheme achieves about 8% to 22% throughput gain and better UE fairness.
