MR-DC – Multi-RAT Dual Connectivity
MR-DC is the general term given to a range of different Dual Connectivity configuration options, largely associated with 5G. With MR-DC, the Master RAN Node functions as the controlling entity, utilizing a Secondary RAN for additional data capacity. Example MR-DC configurations include EN-DC (E-UTRA – NR Dual Connectivity), NR-DC (New Radio Dual Connectivity), NGEN-DC (NG-RAN – E-UTRA Dual Connectivity) and NE-DC (NR – E-UTRA Dual Connectivity).
