An energy-efficient resource allocation method is provided for the downlink massive Multiple-Input Multiple-Output(MIMO) Frequency Division Duplexing(FDD) system, which jointly evaluates the channel estimation stage and data transmission stage. The optimization problem is established based on the Energy Efficiency(EE) maximization by adjusting the pilot duration, pilot power and data power under the constraint of total transmit energy and spectral efficiency requirement. Since the analytical expression of t...
