1. Introduction Link adaptation is a core feature in 5G NR that enables dynamic adjustment of transmission parameters — mainly the Modulation and Coding Scheme (MCS) — based on real-time wireless channel conditions. This process ensures optimal throughput and reliability for each User Equipment (UE) by adapting to mobility, interference, fading, and changing network scenarios. Modern 5G networks advance beyond 4G LTE by employing smarter, faster, and more flexible link adapta
