In short, UE will be having connection with two different eNodeB/sites in the same coverage area. This is advanced version of Carrier Aggregation in which two different sites serves the UE and provide higher throughput. Data packets will be splitted at PDCP layer and will be transmitted to UE using lower layers such ash RLC, MAC of Master and Secondary eNodeBs.
It's kind of LTE-Wifi AP aggregation concept.

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.
