1. A small-node device for offloading data traffic in a cellular telecommunications system, comprising:
- a base-station-to-the-small-node-device (BS2D) communication section configured to receive a first control-plane message from the base station over a BS2D link;
a small-node-device-to-user-equipment (D2UE) communication section configured to transmit downlink (DL) user-plane data in a first set of time slots over a first frequency resource to a user equipment using a wireless D2UE link established responsive to the first control-plane message, wherein the D2UE communication section is further configured to receive uplink (UL) user-plane data from the user equipment over the D2UE link in a second set of time slots over a second frequency resource group, and wherein the time slots in the second set alternate with the time slots in the first set such that the UL and DL transmissions over the D2UE link do not occur simultaneously; and
a backhaul communication section configured to receive the user-plane traffic data from a server over a backhaul link.

Abstract
A hybrid user equipment and small-node device data offloading architecture is provided. In this hybrid architecture, the small-node device includes a backhaul link to a telecommunication network and/or the Internet. The user equipment can send and receive data through the small-node device using the backhaul link according to a half-duplex FDD radio resource assignment in a wireless link between the user equipment and the small-node device.
