5G and its Configured Grant (CG) scheduling feature are transforming industrial connectivity by reducing latency and enhancing efficiency. Unlike traditional dynamic scheduling, CG pre-allocates radio resources, eliminating the need for repeated resource requests and significantly lowering transmission delays.
Dynamic scheduling in 5G NR can lead to high signaling costs, making low-latency communication difficult. CG addresses this by ensuring seamless, delay-free transmission, crucial for digital twins, motion control, and industrial automation.
To assess CG’s performance, researchers from Universidad Miguel Hernández de Elche (UMH), a Zero-SWARM partner, implemented CG scheduling in 5G-LENA, an open-source 5G NR simulator built on the ns-3 framework. This development enables accurate evaluation of 5G NR’s ability to support time-critical services.
The study also refines OFDMA modeling in 5G-LENA to align with 5G NR specifications, improving resource allocation and minimizing latency.
Tests in an Industry 4.0 scenario confirm that CG scheduling in 5G-LENA delivers latency values consistent with theoretical models, highlighting the importance of efficient radio resource utilization in meeting industrial needs.
