Power efficient transceivers to enable energy-efficient mobile radio systems

The expected development of energy-efficient mobile radio communication systems will be based on appropriate power-efficient base station transceivers. For this purpose, we propose a transceiver with a minimized power consumption obtained by advanced power amplification units, since they are a major cause of power dissipation in mobile systems. Appropriate semiconductor technologies, amplifier concepts, and suitable signal conditioning techniques assure the energy savings. Measures to adapt the power dissipation to the signal power level lead to significant efficiency improvement in low traffic situations. Solutions driven by the transceiver architecture will allow the implementation of features requested by energy-efficient systems and ensure access to higher layer control mechanisms, enabling power management at the system level. The individual power saving contributions of solutions acting at the transceiver level are indicated, but the benefit expected from co-acting solutions in a holistically optimized energy-efficient system can only be analyzed at the mobile radio system level by considering additional measures taken in the radio infrastructure network.
