Dual connectivity related specs in LTE?

Question

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.

Answer 1

I did not get the chance to work on dual connectivity but have some theoretical knowledge on it. You can refer 3GPP 36.842 to get some initial heads up.

Thanks a lot Harshita

Harshita,
Do you know the architecture (Alternative 3C or alternative 3D) in 36.842 in table Table 8.1.1.10-1 v12.0.0 . Does this map to   3GPP TS 36.401 Non standalone architectures.

thanks,
