Abstract :
In the dual connectivity architecture in 3GPP LTE-Advanced systems, a user equipment (UE) with multiple transceivers can be simultaneously connected to two eNBs that operate independently at the radio layer. One of them is designated as a master eNB (MeNB) which can choose to forward a portion of the UE traffic to the secondary eNB (SeNB) over a non-ideal backhaul link, and serve the remaining UE data by itself. In this work we examine how to optimally bifurcate the traffic flow when the MeNB has only statistical information of the SeNB channel state information. A fluid model approximation is used to derive individual and global myopic policies for flow splitting.
