Methods and apparatuses pertaining to device-driven power scaling in advanced wireless modem architectures are described. A processor of a communication apparatus with time-varying peak processing capability during active operations negotiates with a wireless network, to which the communication apparatus is communicatively connected, to select one of a plurality of temporary capability states ranging between zero and peak performance of the communication apparatus. The processor initiates a capability state change such that the communication apparatus enters the selected temporary capability state from a current temporary capability state of the plurality of temporary capability states. The lifetime of the selected temporary capability state exceeds a control information period used by the wireless network to dynamically schedule data transmissions with the communication apparatus. The data transmissions between the communication apparatus and the wireless network are constrained according to the selected temporary capability state.

Techniques are provided that can extend the efficiency of a switching regulator further into the low current region by making use of the available knowledge on predictable load variations and voltage ripple tolerance across different states, providing improved efficiency and reducing total current consumption. The load current requirement in low power states is provided using switch mode rather than linear regulation, the switch mode operation being controlled by a mode dependent control circuit so as to minimize the energy cost of the switching operation in each mode and thus obtain improved efficiency from the power source.
