Abstract:
An apparatus, system, and method for performing PDCCH preparation in RF circuitry 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. A plurality of algorithms to prepare for receiving data form a wireless communication network may be performed independent of the baseband circuitry. After initiating the plurality of algorithms, 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.
