Dual Connectivity - Types

There are couple options how the Dual Connectivity could be configured in 4G and 5G. First of all Dual Connectivity in 4G shall be mentioned. Two eNodeB connected with X2 interface. Both of those connected to EPC. Figure 1 LTE DC As for the migration towards 5G several more options are available: EN-DC The first option is the eNodeB connected to gNodeB with X2 and both of nodes are connected to EPC via S1 interfaces. However the gNodeB in this option is only using S1-U towards SGW. The eNodeB has the MN role and the gNodeB has the SN role. This option is called EN-DC (E-UTRA-NR Dual Connectivity). This and three other options described below are grouped in MR-DC (Multi-Radio Dual Connectivity). Figure 2 EN-DC Overview NE-DC In this option called NE-DC (NR-E-UTRA Dual Connectivity) the gNodeB is MN and the eNodeB is SN. Nodes are connected with Xn. Figure 3 NE-DC Overview NGEN-DC Yet another option one is called NGEN-DC (NG-RAN E-UTRA-NR Dual Connectivity). It is the

Dual Connectivity - Terminology

There is a lot of new terms used in a connection to Dual Connectivity The signaling connection for the UE is anchored at the Master Node. The cell UE is using in the MN node is called PCell Primary Cell. The UE also use the cell from the Secondary Node and this cell is called PSCell Primary Secondary Cell. All radio resources used within MN are refered as MCG Master Cell Group, the resources from the SN are referred as SCG Secondary Cell Group. Figure 1 illustrates all those terms. Figure 1 PCell, PSCell, MCG and SCG While using PCell and PSCell, or rather Dual Connectivity, it is also possible to use Carrier Aggregation within both Master Node and Secondary Node. One or more SCells Secondary Cells might be configured. This is shown in Figure 2. Figure 2 PCell, PSCell and SCells
