Fig. 12From: Energy efficiency analysis of hybrid-ARQ relay-assisted schemes in LTE-based systemsEnergy efficiency versus spectral efficiency. HARQ-CC and IR protocols are used. Cooperative transmissions are considered, and the adopted modulations are : 4, 16, and 64QAM. PDYN,BB+PST,BB+PST,RF are taken into account in the energy efficiency computationBack to article page
