Abstract
A terrestrial transceiver beamforms an uplink signal from an airborne transceiver. In the terrestrial transceiver, a radio wirelessly receives an airborne transceiver Identifier (ID) and reference signals from the airborne transceiver. A Baseband Unit (BBU) determines a beamforming instruction based on the airborne transceiver ID and the reference signals. The radio wirelessly transfers the beamforming instruction to the airborne transceiver. The airborne transceiver beamforms the uplink signal based on the beamforming instruction. The radio wirelessly receives the beamformed uplink signal from the airborne transceiver. The BBU receives the beamformed uplink signal from the radio.
