Apparatus, system, and method for parallelizing UE wakeup process

摘要

An apparatus, system, and method for parallelizing user equipment (UE) wakeup process are described. In one embodiment, power may be provided to a crystal oscillator to exit a first sleep state. One or more clocking signals may be provided to RF circuitry based on output from the crystal oscillator. Calibration and state restoration of the RF circuitry may be performed independent of baseband circuitry. State restoration of the baseband circuitry may be performed. Data may be received from a wireless communication network using the RF circuitry. The data may be processed using the baseband circuitry. State retention for the RF circuitry and the baseband circuitry may be performed. Finally, the crystal oscillator may be powered down to enter a second sleep state.
