Dual connectivity (DC) allows user equipments (UEs) to receive data simultaneously from different eNodeBs (eNBs) in order to boost the performance in a heterogeneous network with dedicated carrier deployment. Yet, how to efficiently operate with DC opens a number of research questions. In this paper we focus on the case where a macro and a small cell eNBs are inter-connected with traditional backhaul links characterized by certain latency,

In Release14/15 for to support Dual Connectivity Xn user plane interface was introduced.
which is similar to S5(PGW <=> SGW)/S1(eNB <=> SGW) interface means GTP-u over UDP.

In 36.425 Xn has status report which lost packet range with start and last packet. What is the significance of having those in status report?

Does MeNB Xn has to re-transmit lost packets over Xu?
Or Also in Xn status report we have "Highest successful delivered PDCP seqence number", how SeNB Xn will get the PDCP sequence number while sending the status report?

If SeNB Xn has to send feedback report at interval it has to send?

Could anyone please clarify the above queries.
