SINOPSIS

Macro evolved Node B (eNB) is an inevitable element to provide ubiquitous coverage for mobility in the urban area and the long reach in the rural area. But, it consumes more than 70% of total power consumption of access network. Enabling multiple power efficient techniques increases the power efficiency of the eNB with the cost of adding non-linearity. Tradeoff between power efficiency and linearity while selecting the combination of various power efficient techniques including peak to average power reduction, N-way Doherty power amplifier (DPA), efficient system integration and turning on and off eNB based on data traffic are discussed in this paper. Simulation results reveals that the integrating of multiple power efficient techniques simultaneously can lead up to 46.9% saving in the power consumption with respect to conventional macro eNB along with 2-way DPA. This reduction will be benefitted in terms of operational expenditure (OPEX) of the access networks and CO2 emissions from cellular network.
