In this paper, we propose a new Radio Resource Allocation scheme for Downlink OFDMA-based 5G New Radio, where the scheduler inside a Next Generation Node B jointly allocates Resource Block Groups to users requiring Guaranteed Bit Rate (GBR) or non-GBR services. We propose two different strategies which exploit the complete view of the channel conditions perceived by User Equipements. The goal is to achieve a good trade-off between maximizing the system throughput and improving the fairness among users, while guaranteeing minimum bit rate requirements. We benchmark our approach against other existing resource allocation algorithms via several system-level simulations, under different traffic and channel conditions. The comparative analysis shows that our control scheme outperforms the reference schemes in terms of throughput and fairness, while guaranteeing a larger number of GBR services.

Abstract

In this paper, we propose a new Radio Resource Allocation scheme for Downlink OFDMA-based 5G New Radio, where the scheduler inside a Next Generation Node B jointly allocates Resource Block Groups to users requiring Guaranteed Bit Rate (GBR) or non-GBR services. We propose two different strategies which exploit the complete view of the channel conditions perceived by User Equipements. The goal is to achieve a good trade-off between maximizing the system throughput and improving the fairness among users, while guaranteeing minimum bit rate requirements. We benchmark our approach against other existing resource allocation algorithms via several system-level simulations, under different traffic and channel conditions. The comparative analysis shows that our control scheme outperforms the reference schemes in terms of throughput and fairness, while guaranteeing a larger number of GBR services.
