报告摘要：

The exponential increase of wireless devices and the demand for higher communication rates has put forward the issue of sustainable growth of modern wireless communication systems. Future wireless networks will be required to provide much higher data-rates, but at a similar power consumption as present networks. This makes energy efficiency optimization a natural need and a crucial challenge in present and future wireless networks.

The talk will formally define the concept of bit-per-Joule energy efficiency, describing the fundamental tools to formulate and solve energy efficiency problems in wireless networks. In particular, the theory of fractional programming will be introduced, as the natural tool for energy efficiency maximization.

A general framework will be provided to perform energy efficiency maximization in practical, interference-limited wireless networks. It will be shown how this general framework applies to several instances of wireless networks, including multi-carrier LTE systems, multiple-antenna systems, as well as many 5G candidate technologies. Both centralized and distributed schemes will be discussed and compared in terms of performance, feedback requirements, and computational complexity.
