The structure of Multi-user Feature Mode Transmission (MET) is analyzed and a scheduling algorithm with low complexity is studied, and an adaptive proportional fair scheduling algorithm is also studied.The multi-user feature mode transmission is adopted at the base station to eliminate inter-user interference , Increase the throughput of the system, and at the same time, use the proportional fair scheduling and the adaptive proportional fair scheduling algorithm to improve the fairness of the system while ensuring the user transmission rate, and select the optimal user set for transmission at the same time. Simulation and analysis show that: The combination of channel characteristic mode transmission and adaptive proportional fairness not only guarantees the system speed but also improves the fairness of the system.
