Embodiment 1
[0082] A resource allocation method in an energy harvesting small cell network, characterized in that it comprises:
[0083] Step 1: system scene analysis, problem analysis;
[0084] The present invention considers a classic three-node scenario in an energy-harvesting small-cell network, and aims at a special application scenario, sourced from practical applications, and the scenario setting is meticulous and reasonable, and has practical guiding significance. In the scene, there is an energy harvesting small cell Small Cell (abbreviated as S), an energy harvesting relay station Relay (abbreviated as R) and a target communication cellular user Destination (abbreviated as D). The invention fully considers the environmental protection scheme of renewable energy, combines the cooperative forwarding function of the relay station, adopts the cooperative forwarding data of the energy collection relay station, and maximizes the performance of the user network.
