Minimizing Base Station Power Consumption [PDF]
IEEE Journal on Selected Areas in Communications, 2014 We propose a new radio resource management algorithm which aims at minimizing the base station supply power consumption for multi-user MIMO-OFDM. Given a base station power model that establishes a relation between the RF transmit power and the supply power consumption, the algorithm optimizes the trade-off between three basic power-saving mechanisms ...
