Proportional fair scheduling method with QoS for the coexistence system of GFDM and OFDM

摘要

Future 5th generation (5G) mobile system is required to accommodate a huge amount of mobile data traffic with different quality of services (QoS) in a large number of devices. To realize 5G system, a new waveform such as generalized frequency division multiplexing (GFDM) has been researched. In this paper, we propose a proportional fair (PF) scheduling method considering the delay budget of users for the coexistence system of GFDM and orthogonal frequency division multiplexing (OFDM). From computer simulation, we show that the proposed method can improve the average delay time for users of small delay budget without large degradation of system throughput.
