摘要： Adaptive path selection for interference cancellation is provided for wireless communication devices. Signal strength metrics are obtained for each of multiple signal paths. One or more of the signal paths are selected as cancellation candidates in response to determining that the signal paths are associated with a strong interfering path based at least in part on the signal strength metrics for the signal paths and threshold criteria. Cancellation is enabled for an estimated signal generated using the signal paths in response to the signal paths being selected as cancellation candidates.

摘要： A technique for receiving paging information helps a mobile communication device with multiple SIMs to better determine that a call is incoming. Despite the paging indicators for both SIMs arriving in a manner that prevents both the paging indicators from being received, the technique is able to ascertain whether a SIM is being paged, even when the other SIM is currently on the radio interface. As a result, the mobile communication device exhibits an increased ability to detect and alert the user to incoming calls.

摘要： 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.

摘要： Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A timing conflict may exist when a scheduled high priority communication of a first SIM overlaps with a scheduled paging monitoring activity for a second SIM. The multiple SIM device may preempt transitioning communication resources to the second SIM when the first SIM executes high priority communications. Or, the multiple SIM device may execute a rescheduling action to resolve the timing conflict. The high priority communication of the first SIM may be rescheduled. Alternatively, normal priority paging monitoring actions may be rescheduled to resolve the timing conflict.

摘要： 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.

摘要： A frequency control system enhances user equipment performance. The user equipment may include multiple SIMs, and the frequency control system may facilitate successful background page monitoring for a SIM that is not currently active. In particular, the frequency control system may track environmental factors that influence time base accuracy in the user equipment. When the background page monitoring activity happens for the inactive SIM, the frequency control system may apply a correction to the time base that facilitates successful reception of the paging indicators for the inactive SIM.

摘要： A technique for tuning the receiver (RX) synthesizer independently from the transmitter (TX) synthesizer helps a mobile communication device with multiple SIMs to concurrently monitor the paging channel of a first network associated with one SIM while transmitting on a second network associated with a second SIM. By independently tuning the RX and the TX synthesizers, each SIM card can maintain synchronization with the network without disruption of service in either network. As a result, the mobile communication device exhibits an increased ability to maintain communication sessions for two different networks, without the need for a second set of TX/RX synthesizer hardware.
