New 5G AI framework predicts retransmissions to boost efficiency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed NOSTRAdAMUS, a predictive framework designed to enhance link adaptation in 5G NR networks. This system forecasts retransmissions based on HARQ history, allowing for proactive adjustments to Modulation and Coding Scheme (MCS) selections. Utilizing a Gradient Boosting model trained on over-the-air data from the X5G testbed, NOSTRAdAMUS achieved 82.9% accuracy and demonstrated significant improvements in goodput and retransmission reduction across various channel conditions. AI

IMPACT This research could lead to more efficient and reliable 5G networks by enabling proactive rather than reactive link adaptation.

    Improving 5G AI-RAN MCS Selection by Predicting Retransmissions

    arXiv:2609.09324v1 Announce Type: cross Abstract: Link Adaptation (LA) in 5G NR is inherently reactive, relying on channel measurements and HARQ feedback that may become quickly obsolete when the channel changes quickly. This data is also noisy, making it hard to track accurately…
