Predicting HARQ Retransmissions to Improve MCS Selection in 5G AI-RAN
Researchers tackle a weakness in 5G link adaptation, where modulation and coding scheme choices depend on channel measurements and HARQ feedback that quickly become outdated in fast-changing conditions. Their data-driven approach predicts the likelihood of retransmissions, allowing the network to select more robust transmission parameters proactively. The work targets AI-enhanced radio access networks, where such predictions could improve throughput and reliability.
