Introduction This contribution presents typical basic transport architecture as defined by the NGMN Alliance white paper [1]. Main purpose is to aid with the definitions of terminology and target requirements for small-cells backhaul, noting that white paper does not cover the more advanced features of IMT-Advanced such as Carrier aggregation, CoMP, high order MIMO etc. This contribution only cover higher level description of network architecture, and link topologies without touching on the capacity or QoS requriments. These could be covered by another contributions.

Overview of Backhaul Architecture The purpose of the transport links shown in green in the figure above is to provide connectivity between the small cells and the core network nodes with desired QoS level.
