Method and apparatus at the physical and link layer for mobile communications
First Claim
1. In a cellular telecommunications network, a radio base station to control a user equipment (UE) and a plurality of small-node devices, the radio base station comprising:
- a macro-base-station-to-the-UE (BS2UE) communication transmitter/receiver exchanges user-plane and first control-plane data with the UE using a wireless BS2UE communication link;
a macro-base-station-to-the-small-node-device (BS2D) communication transmitter/receiver exchanges second control-plane data with at least one of the plurality of small-node devices using a BS2D communication link; and
a small-node-device-to-the-UE (D2UE) control processor controls an establishment and also a release/reconfiguration/handover of a D2UE communication link through a first control-plane data and/or a second control-plane data transmitted to at least one of the UE and the plurality of small-node devices using one of the BS2UE and BS2D communication links,wherein data in the D2UE communication link is scrambled by a sequence specific to a mobile station.

Abstract
In a cellular telecommunications network, a mobile communication system to offload data traffic from base stations to small-node devices, includes a radio base station, a plurality of small-node devices, a macro-base-station-to-the-small-node-device (BS2D) communication section configured to receive a first control-plane message from the radio base station over a BS2D communication link, a small-node-device-to-user-equipment (D2UE) communication section configured to transmit user-plane data to a user equipment over a wireless D2UE communication link established responsive to the first control-plane message, and a center small-node device. The center small-node device includes a buffer section, a backhaul communication section configured to receive the user-plane traffic data from a server over a backhaul link, and is configured to manage D2UE connections between the plurality of small-node devices and the mobile station, buffer data to be transmitted in downlink and uplink for the plurality of small-node devices, and conduct a link adaptation for the D2UE connections.
