    Abstract: A scheduling technique is described for discontinuous transmission and reception. The scheduling technique may be implemented in a mobile communication device with multiple SIMs. The scheduling technique facilitates enhanced communication capability for the mobile communication device. In one implementation, the scheduling technique helps avoid substantial overlap between discontinuous receive cycles of the SIMs, for example by renegotiating a discontinuous transmit/receive offset if too much overlap exists. The renegotiation process may be incorporated into a future industry standard communication protocol (e.g., 3GPP release 11 or later), or may be implemented as an extension to an existing communication protocol.

    Abstract: A technique to provide hybrid compensation to correct for drifts in a reference frequency output from a digitally-controlled crystal oscillator (DCXO). A first compensation is provided to the DCXO to adjust for overlap or discontinuity of the reference frequency caused by switching capacitors in the capacitor array that controls drift of the reference frequency output. The second compensation is obtained at a phase-locked loop (PLL) that receives the reference frequency signal from the DCXO. The second compensation adjusts the PLL to adjust for variations of the reference frequency that remain after performing compensation in the DCXO.

    Abstract: Idle mode power consumption reduction in wireless communications. Within a wireless communication device that is operative to communicate with any one of a number of servicing cells, paging broadcasts from more than one of these servicing cells are received and undergo only a limited amount of processing before being stored for use in subsequent processing that may be performed later. This partitioned processing allows the turning off of certain components that are not needed and/or no longer needed for determining the system frame numbers associated with various servicing cells to effectuate timing synchronization. Certain modules within such a wireless communication device may perform processing using the full capabilities of the wireless communication device to generate initially processed signal, and then after such signals are stored, then only partial processing capability of the wireless communication device may be employed, even though perhaps being slower, to complete the processing.
