    Mar, 2019 by Pankaj in MR-DC, MR-DC with the 5G There are three possible MR-DC with the 5GC architectures as follow:  1. E-UTRA-NR Dual Connectivity: NG-RAN supports NG-RAN E-UTRA-NR Dual Connectivity (NGEN-DC), in which a UE is connected to one ng-eNB that acts as a MN and one gNB that acts as a SN.
    DC between LTE/5G MN and LTE/5G SN is known as Multi-RAT Dual Connectivity (MR-DC) . The control signaling procedures in these different modes are not uniform and differ in many aspects. For instance, in LTE DC, control information for a UE can be transferred via MN only while in MR-DC, it can be transferred via MN or MN and SN both.
    The Core Network ( CN) is either LTE EPC or 5G Core. This was later expanded so that both cells can belong to 5G NR, in which case the CN is exclusively 5G Core. These various options come under the general term Multi-Radio Dual Connectivity (MR-DC). MR - DC is a generalization of Intra- E-UTRA Dual Connectivity.
    According to the 3GPP NR Release 16 standard , Multi-Radio Dual Connectivity (MR-DC) is the term that is generally being used for MC. Dual connectivity (DC) refers to the lower bound of MC where the UE is connected to only two APs.

    WEBOct 14, 2022 · MR - DC is a generalization of Intra- E-UTRA Dual Connectivity. MR - DC can offer a UE more resources for higher throughput. More commonly, it helps operators improve mobility robustness and handovers in macro/micro-cell deployments. It aids in migrating their …

  3. WEBNov 30, 2020 · The newest MR-DC configuration supported by 5G NR is the NR-NR Dual Connectivity (or simply NR-DC) shown in Figure 1(c). Unlike the other DC architectures, the UE in NR-DC is connected to two …

      WEBThese three bearer types are depicted in Figure 4.2.2-1 for MR-DC with EPC (EN-DC) and in Figure 4.2.2-2 for MR-DC with 5GC (NGEN-DC, NE-DC). In this page, I will explain only on a specfic type of bearer mentioned above called 'Split Bearer' since it may be a kind of confusing concept. …
