Hi All,
Please welcome to my channel techlteworld .
ENDC -Dual Connectivity (EN-DC) which enables 5G services and 4G network.
UEs supporting EN-DC can connect simultaneously to LTE Master Node eNB and 5G-NR Secondary Node gNB.
UE first register with 4G EPC through ENDC.
Based on UE supportability it starts reporting measurement on 5G Frequencies and LTE nodeB communicate with g-NB For 5G resource assignment.
The 5G-NR resource assignment is then signaled to the UE via an LTE RRC Connection Reconfiguration message.
After RRC Connection Reconfiguration procedure completion, the UE simultaneously connects to the 4G and 5G networks.
