  • Patent number: 9426685
    Abstract: A UE, in an idle mode, receives pilot signals and synchronization signals from a serving cell and neighbor cells comprising neighbor cells listed and/or unlisted in a neighboring cell list. The UE validates each of the serving cell, the listed neighbor cells and the unlisted neighbor cells from the received signals. The UE performs cell measurement on the listed cells as well as the unlisted cells for multipath profiles and associated power levels. In instances where number of attempts of the cell measurements on the unlisted cells exceeds a threshold value, the UE may validate presence of the unlisted cells. The best available cell is selected from the listed cells and the unlisted for the UE to camp on. I/Q samples of the received signals are stored while measuring or monitoring the cells. The stored I/Q samples may be utilized to carry out baseband procedures through offline processing.

  • Patent number: 9277499
    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.
