    Abstract: A user equipment (UE) performs wireless communication by starting a scan of an absolute radio frequency channel number (ARFCN) configured for performing a narrowband communication. The UE determines, based on a spectral characteristic of a phase of a signal in the ARFCN, whether a cellular communication is deployed in the ARFCN. The UE may then terminate the scan of the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is deployed in the ARFCN. Alternatively, the UE may proceed with a synchronization signal search on the ARFCN in response to the spectral characteristic of the phase of the signal in the ARFCN indicating that the cellular communication is not deployed in the ARFCN.

    Abstract: Methods and devices are disclosed for enabling improved scheduling of non-time bounded tasks across multiple subscriptions of a multi-subscription wireless communication device. A processor of the wireless communication device may determine whether the frequency utilized by a radio access technology (RAT) of a first subscription interferes with one or more frequencies utilized by RATs of other subscriptions. In response to determining that two or more of the subscriptions are non-interfering (i.e., RAT frequencies do not interfere) the processor may co-mingle non-time bounded tasks with time bounded tasks of the same subscription to produce consolidated task blocks. The task blocks may be temporal chunks of an execution queue in which tasks are scheduled continuously without interim idle periods. The processor may execute the first task block of each execution queue concurrently across subscriptions to reduce the amount of time that only a portion of the subscriptions are active or dormant.

    Abstract: Various embodiments enable cell broadcast reception on a multi-SIM mobile communication device with first and second subscriptions for respective technologies. A multi-SIM device may measure channel conditions for the first and second radio access technologies, determine whether the channel conditions of the first radio access technology are greater than or equal to a threshold for receiving cell broadcasts, determine whether the channel conditions of the second radio access technology are greater than or equal to the threshold when the channel conditions of the first radio access technology are less than the threshold, and designate the second radio access technology to receive cell broadcasts when the channel conditions of the second radio access technology are greater than the threshold and disabling cell broadcast reception on the first radio access technology. A Voice or Data call mode on one technology may require another technology to be designated to receive cell broadcasts.

    Abstract: Methods, systems and devices are provided for selecting one or more target devices for device-to-device (D2D) communication with a device. A device processor may determine whether a battery power level of the device is below a threshold battery power level. The device processor may establish a received power level threshold in response to determining that the battery power level of the device is below a threshold power battery level. The device processor may determine whether a received power level of a signal from target devices for D2D communication is above the received power level threshold. In response to determining that the received power level from a target device is above the received power level threshold, the device processor may permit D2D communication with that target device.

    Abstract: Aspects of the present disclosure are directed to an apparatus and methods capable of pre-correcting reacquisition slew of pilot signal timing when a mobile device operates in a slotted mode or discontinuous reception (DRX) mode. In one aspect, a mobile device is operated in slotted mode. The mobile device wakes up to perform a pilot reacquisition corresponding to a slotted mode and detects a slew of a pilot timing relative to a pilot reference timing. The mobile device adjusts a subsequent pilot reference timing by an amount corresponding to the detected slew, to be utilized during a subsequent wake-up cycle. The mobile device returns to a sleep state to wait for the subsequent wake-up cycle. Other aspects, embodiments, and features are also claimed and described.

    Abstract: Embodiments include systems and methods for managing inter-radio access technology (IRAT) procedure concurrency between subscriptions on a multi-subscription multi-active communication device. A device processor may identify a higher-priority subscription and a lower-priority subscription on the multi-subscription multi-active communication device. The device processor may determine whether an IRAT procedure on the lower-priority subscription will overlap in time with an IRAT procedure on the higher-priority subscription. The device processor may calculate a deferral time period for the lower-priority subscription in response to determining that the IRAT procedure on the lower-priority subscription will overlap in time with the IRAT procedure on the higher-priority subscription. The device processor may defer performance of the lower-priority subscription IRAT procedure using the deferral time period in order to perform the IRAT procedure on the higher-priority subscription, and may perform the IRAT procedure on the lower-priority subscription after the deferral time period.
