Abstract

For controlling energy-consumption associated with data transmission between a terminal device ( 200 ) and a mobile network a node of the mobile network which is responsible for scheduling the data transmission, e.g., a base station ( 100 ) or a control node ( 300 ) obtains an energy consumption profile of the terminal device ( 200 ). The energy consumption profile specifies characteristics of multiple energy sinks in the terminal device ( 200 ). On the basis of the energy consumption profile, the node performs scheduling of the data transmission.
