Abstract

Given the massive increase in network infrastructure required to provide the high capacities expected in current wireless systems due to the exponential growth in mobile data consumption, substantial improvement in energy efficiency of the current 4G systems is necessary. High energy efficiency results in low operational cost and sustainable network deployment. In this paper, we propose a new receiver puncturing technique and a novel energy efficient dynamic resource allocation scheme. Improvements in BER performance and 20%~25% transmit-energy expenditure reduction, as compared to conventional proportional fair resource allocation schemes, are shown by both link level and system level simulations of a multi-cell downlink orthogonal frequency-division multiple access (OFDMA) system. Finally, the complexity issues inherent to the proposed technique are also evaluated.
