SENB will be only one but SENB can have multiple CC. at a time only one SENB will be active with multiple CC. CC is carrier component .
As i know single SENB can have mltiple cells but can i have multiple SENB?
What is the possibility of cross carrier scheduling in dual connectivity?
On what basis eNB splits the packet in dual connectivity? will it offload entire load to gNB or 50/50 ?
