Adaptive Cost-Reward Scheduling for Optimizing Radio Utilization and NR Numerology Efficiency in B5G New Radio Networking

The importance of having fast and reliable communication that can move with you is clear in critical areas like emergency response, ASD, eV2X communication, and LEO connectivity. The emergence of B5G/5G technology represents a transformational leap within the 3GPP standard, providing a flexible NR SCS mode tailored to the diverse 5QI requirements, which include latency, data rate, jitter, loss, and reliability. Efficient flow scheduling in B5G radio networks can be a challenging task, especially in SDN paradigms. Existing research has proposed scheduling methods. However, they often prioritize traditional QoS requirements and overlook critical factors such as bearer costs and associated rewards. In this paper, we present a novel Cost-Based Flow Scheduling (eSCFS) framework that utilizes an extended Sigmoid function to dynamically prioritize flows, taking into account all relevant factors. Our main goal is to reduce latency while maximizing the use of radio RB and bringing maximization net benefits to B5G NR networks. The eSCFS method has been validated through numerical simulations, demonstrating superior performance across key metrics such as network latency, resource utilization, and overall profitability. This Paper therefore aims to achieve and contribute to several objectives: 1) analyze the QoS requirements of various services within limited radio resources, 2) proposing a vRB state-dependent dynamic flow scheduling scheme to maximize network performance, 3) proposing an adaptive scheduling approach based on cost-reward considerations.
