Abstract
Future cellular networks will be more dense and heterogeneous. A typical deployment will be based on micro, pico and femto cells. Under this scenario, novel interference management techniques such as network MIMO will be mandatory. However, it is usual to combine them with power allocation strategies to maximize the sum of the rates or minimize the power consumption. Those strategies are unfair at user level in heterogeneous networks and do not provide a "green" measure. In this work we propose some more equitable alternatives to the classical power allocation schemes and a strategy based on a green metric. Finally we compare the performance, in user spectral efficiency and power consumption terms, of these strategies in micro and femto cell deployments.
