Abstract [en]

Energy efficiency is becoming increasingly importantfor mobile devices because battery technology has notkept up with the growing demand of ubiquitous multimediacommunications. Since multi-user multiple-input multiple-output(MU-MIMO) is a key technology in next-generation wirelesscommunications, this paper addresses optimal energy-efficientdesign for MU-MIMO. The energy efficiency is measured by aclassic metric, “throughput per Joule”, while both RF transmitpower and device electronic circuit power are considered. Wedefine the energy efficiency (EE) capacity for MU-MIMO andstudy the power allocation that achieves this capacity. We showthat user antennas should be used only when the correspondingsubchannels are sufficiently good and using them improves theoverall network EE. Based on theoretical analysis, we further developlow-complexity yet globally optimal energy-efficient powerallocation algorithms that converge to the optimum exponentially.Finally comprehensive simulation results are provided todemonstrate the significant gain in network energy efficiency.
