New Transmission Technique which can Save Energy in Uplink Thanks to Supportive Transmission in Downlink

New transmission technique is presented, which can save energy in uplink thanks to supportive transmission in downlink. It could be applied in future IoT particularly for WSN applications in certain scenarios in which a central node with enough energy is collecting information from sensor nodes with limited energy resources. The central node must be able to predict the expected message in such a way that there is some correlation between its supportive message and the expected message from the selected sensor node.
