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.
