Coordinated Link Adaptation and Higher Layer Error Correction for 5G Broadcast / Multicast

3GPP RAN plenary meeting #84 in Newport Beach, US, in June 2019, discussed the content of 5G New Radio (5G-NR) Release 17 standardization. One of the defined key areas for 5G enhancements for 5G enhancements is NR Broadcast / Multicast (BC/MC). Important use cases for this technology are NR Vehicle-to-Everything (V2X), NR Public Safety and NR Non-Terrestrial Networks (NTN). This white paper proposes a mechanism of link adaptation in coordination with higher layer Error Correction. A detailed description and system-level simulation-based evaluation of the proposed scheme is provided in this White Paper.
