Real-Time Algorithms for Combined eMBB and URLLC Scheduling.
International ITG Workshop on Smart Antennas(2024)
摘要
In modern communication networks, particularly in private 5G networks, the coexistence of devices with different quality of service requirements, such as ultra-reliable low-latency communications (URLLC) and enhanced mobile broadband (eMBB), needs to be ensured. This necessitates efficient and real-time scheduling algorithms, despite the NP-hardness of such resource allocation problems. In this paper, we investigate scheduling algorithms that address this challenge. For this, we assume a punctured scheduling framework that initially allocates all resources among eMBB user equipments (UEs), while, subsequently, some of the allocated resources are punctured by incoming URLLC traffic. We propose a low-complexity algorithm that outperforms state-of-the-art algorithms and exhibits only a marginal performance gap compared to a computationally highly expensive commercial solver for the underlying optimization problem. Moreover, we investigate the influence of different scheduling algorithms under varying load conditions.
