Given the massive increase in network infrastructure requiredto provide the high capacities expected in current wirelesssystems due to the exponential growth in mobile data consumption,substantial improvement in energy efficiency of the current 4G systemsis necessary. High energy efficiency results in low operationalcost and sustainable network deployment. In this paper, we proposea new receiver puncturing technique and a novel energy efficientdynamic resource allocation scheme. Improvements in BERperformance and 20% 25% transmit-energy expenditure reduction,as compared to conventional proportional fair resourceallocation schemes, are shown by both link level and system levelsimulations of a multi-cell downlink orthogonal frequency-divisionmultiple access (OFDMA) system. Finally, the complexity issuesinherent to the proposed technique are also evaluated.
