To my knowledge it depends on architecture scenario.
In 3x scenario as it is expected to be deployed by early 5G adopters, MeNB can triger both . Maybe some vendors will allow in first drops just one option but standard allows both.

While digging into 5G NR dual connectivity, ( and as you are aware that it is based on LTE dual connectivity). I want to learn a bit about how LTE put the foundation for this feature to come towards 5g.

I want to read the LTE architecture specs related to dual connectivity.
I donot have much RAN background in LTE. Could somebody from this background give me some quick hints, to look into which 3gpp TS or TR to understand some basics.

Btw there is 3GPP TS 36.401 doesnot have much info it looks like.
