Abstract: Performing detection of a synchronization beacon. The UE may include a first radio which supports, e.g., simultaneously, a first radio access technology (RAT) and a second RAT. The UE may perform transmission according to the first RAT on the first radio with a base station. The UE may receive a request to perform a tune-away to detect a synchronization beacon on the second RAT. The synchronization beacon may repetitively occur in successive first time periods. The UE may repeatedly perform a search for the synchronization beacon in different sub-portions over successive first time periods. The search may be repeatedly performed until the synchronization beacon is located in a respective sub-portion of one of the successive time periods.

Abstract: Performing data communications by a Dual SIM Dual Active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls. The UE may receive a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE may then determine whether one of the voice calls is currently on hold. The UE may perform the data communications using the radio on which the held call is being conducted. The UE may therefore dynamically select available slots from the first radio and the second radio for performing the data communication, based on which of the first radio and the second radio has a voice call that is currently on hold. In some embodiments, the data communications may be performed using a Long Term Evolution (LTE) protocol stack.

Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry of a wireless communication device. The wireless communication device establishes a connection to a first wireless network using first and second receiving signaling chains. In response to detecting a radio frequency tune-away event, the wireless communication device reconfigures only one of the radio frequency signaling chains to receive signals from a second wireless network when a set of receive signal conditions for the second wireless network is satisfied. The wireless communication device reconfigures both of the radio frequency signaling chains to the second wireless network when the set of receive signal conditions is not satisfied.

Abstract: Operating a user equipment (UE) which comprises a first radio that is configured to operate according to a first radio access technology (RAT) and a second RAT. The UE may receive a request to perform a tune away operation for the second RAT while performing measurement for the first RAT (e.g., intra-cell measurement, inter-cell measurement, and/or inter-RAT measurement). Instead of waiting to complete the measurement of the first RAT, the UE may tune the radio to a frequency of the second RAT to perform the tune away operation (e.g., page decoding) for the second RAT. After completing the tune away operation of the second RAT, the UE may tune the radio back to a frequency corresponding to the first RAT in order to continue the measurement operations of the first RAT.

Abstract: Methods and apparatus for the automated altering of wireless device states in response to detected connection behaviors. In one embodiment, a mobile device receives network parameters, some of which are incorrectly configured, from a base station (or access point). To ensure the proper behavior of the mobile device, the device reviews the network provided parameters to determine if one or more of the parameters has been set incorrectly. If so, the device locally alters its own settings to mitigate the incorrect operation associated with the incorrect network provided parameters. In second exemplary embodiment, a number of tolerances are utilized to ensure the proper operation of the mobile device while maintaining an active link. Upon violation of one or more of these tolerances, the device breaks the active link to the wireless network.

Abstract: Performing concurrent data communication and voice call monitoring using a single cellular radio. According to some embodiments, the UE may perform data communication, via the radio, using a first RAT, supported by a first SIM. The UE may also perform paging functions for a voice communication, via the radio, using a second RAT, supported by a second SIM. In some scenarios, the first and second RATs are the same. The data communication and the paging functions may be performed concurrently using shared physical layer resources. For example, the shared physical layer resources may comprise a shared software defined radio (SDR) configured to demodulate and/or decode signals of the data communication and the paging function. As another example, the shared physical layer resources may comprise a shared Rake receiver configured to demodulate signals of the data communication and the paging function.

Abstract: Methods and apparatus for adaptively adjusting temporal parameters (e.g., neighbor cell search durations). In one embodiment, neighbor cell search durations during discontinuous reception are based on a physical channel metric indicating signal strength and quality (e.g. Reference Signal Received Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Receive Quality (RSRQ), etc.) of a cell. In a second embodiment, neighbor cell search durations are based on a multitude of physical layer metrics from one or more cells. In one variant, the multitude of physical layer metrics may include signal strength and quality metrics from the serving base station as well as signal strength and quality indicators from neighbor cells derived from the cells respective synchronization sequences.

Abstract: Operating a UE device having a single radio configured to communicate using a first and second RAT. The UE may begin operating in a connected discontinuous reception (CDRX) mode of the first RAT, where the CDRX mode comprises an on duration timer and an inactivity timer. The method may determine that the single radio of the UE is being used for a second RAT during the CDRX mode. The UE may operate at least one of a CDRX on duration timer or an inactivity timer of the first RAT while the single radio of the UE is being used for the second RAT. While the single radio of the UE is being used for the second RAT, the at least one of the CDRX on duration timer or the inactivity timer may operate even though no communication or monitoring is performed on the first RAT.
