Type of Dual Connectivity
Home LTE NB-IoT 5G(NR-NSA) Today, we will learn about different type of Dual Connectivity between NR and LTE. If you are interested in learning more about 5G please click here . What is MR-DC? MR-DC stands for Multi-Radio Dual Connectivity. UEs which support multiple Tx/Rx can be configured to utilize resources from two different nodes. One of these nodes could provide NR access and the other one could provide either E-UTRA or NR access. One node will act as the Master Node (MN) and the other as the Secondary Node (SN). MR-DC with the EPC (legacy LTE Core): Legacy LTE (E-UTRAN) supports MR-DC through EN-DC (E-UTRA-NR Dual Connectivity). 1) EN-DC DUT (device) shall connect to one eNB that is acting as a master-node (MN) and one en-gNB acting as a secondary-node (SN). The master-nod...
