Abstract: Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.

Abstract: Targeted public land mobile network (PLMN) search by a wireless user equipment (UE) device. A PLMN search may be initiated at the UE. It may be determined whether PLMN search targeting information is available. A targeted PLMN search may be performed if PLMN search targeting information is available. Targeting the PLMN search may include reducing the number of frequencies or frequency bands searched as part of the PLMN search.

Abstract: Techniques involving the management of display parameters are disclosed. For example, an apparatus may include a display, a radio module, and a control module. The display employs various operational parameters, which can take on different values. Exemplary parameters include refresh rate and/or pixel clock rate. The radio module may receive a wireless signal at one or more reception frequencies. The control module may select values for these operational parameters of the display. This selection may be made according to characteristics of interference that would be emitted from the display at the one or more reception frequencies. Upon making this selection, the control module may direct the display to employ the selected parameter values.

Abstract: Transitioning a UE from a first RAT to a third RAT in an area having a first RAT, a second RAT, and a third RAT. The first RAT may be a second generation RAT, the second RAT may be a third generation RAT, and the third RAT may be a fourth generation RAT. The network of the first RAT may not provide information (e.g., a neighbor list) for the third RAT. The UE may use information to perform measurement of one or more base stations of the third RAT without attaching to the second RAT. For example, the UE may use pre-stored information to perform measurement of the third RAT. Alternatively, or additionally, the UE may receive the information (e.g., from a system information block) from the second RAT without attaching to the second RAT.

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: This disclosure relates to techniques for scheduling radio resource control connections between a wireless device and a network element of a network in advance. According to some embodiments, a wireless device may provide an indication of one or more types of upcoming data traffic to the network element. The network element may schedule one or more radio resource control connections for the wireless device based at least in part on the indication of one or more types of upcoming data traffic. The network element may provide an indication of the scheduled radio resource control connection(s) to the wireless device. The wireless device and the network may establish the scheduled radio resource control connection at the scheduled time.

Abstract: Methods and apparatus for intelligent scheduling of client device tasks based on one or more network scheduling constraints. During normal network operation, a client device performs an array of scheduled maintenance tasks to optimize network performance (e.g., signal strength measurements, etc.) However, during hybrid network operation, regularly scheduled maintenance tasks for a first network can interrupt higher priority tasks on other networks. Consequently, the present invention in one embodiment provides a method for a client device to properly prioritize and re-schedule maintenance tasks. For example, CDMA 1X cell selection (or cell re-selection) procedures have flexible time constraints, and can be postponed (or expedited) to minimize impact on LTE network traffic.

Abstract: Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1X operation), a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the LTE and CDMA 1X networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1X paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1X pages, overall LTE network performance is minimally affected.

Abstract: A method to control multiple radio access bearers is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a radio network subsystem in a wireless communication network by first and second bidirectional radio access bearers. The mobile wireless communication device transmits a data packet on an uplink of the first bidirectional radio access bearer to the radio network subsystem. When the data packet is not correctly received by the radio network subsystem, the mobile wireless communication device retransmits the data packet repeatedly. After N retransmissions of the data packet, the mobile wireless communication device releases the first bidirectional radio access bearer while maintaining the second bidirectional radio access bearer. The first bidirectional radio access bearer provides a channel to transport packet switched data, and the second bidirectional radio access bearer provides a channel to transport circuit switched data.

Abstract: Performing data communication using a first radio access technology (RAT) while performing a voice call using a second RAT, using a first radio (e.g., a single radio for cellular communication. The UE may use the first radio to initially perform first data communication using the first RAT. During the first data communication the UE may not be communicating using the second RAT or may not generally maintain a connection to the second RAT. Subsequently, the UE may receive an indication to perform at least one of a mobile originated voice call or receive a mobile terminated voice call using the second RAT. Accordingly, the UE may perform the voice call using the second RAT in response to the indication, using the first radio. Additionally, the UE may perform second data communication using the first RAT during the voice call, using the first radio.

Abstract: Methods and apparatus for modifying network management for hybrid operation. In one embodiment, the networks include an LTE network and a CDMA 1X network, and a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the mobile device cannot simultaneously measure information for the LTE network while connected to the CDMA 1X networks, the mobile device modifies measurements and behaviors reported to the LTE network. In one implementation, the mobile device accounts for the time switched away from the LTE network in one or more subsequent reports thereto.

Abstract: Electronic devices may have multiple wireless integrated circuits such as first and second baseband processor integrated circuits. The first baseband processors may be used exclusively for handling packet switched traffic, whereas the second baseband processor may be used exclusively for handling circuit switched traffic. Radio-frequency front end circuitry may be used to couple multiple antennas to the baseband processors and associated radio-frequency transceivers. The first baseband processor may be coupled to a first universal integrated circuit card (UICC) storing a first subscriber profile, whereas the second baseband processor may be coupled to a second UICC storing a second subscriber profile. The first baseband processor may be used to support any desired circuit switched radio access technology, whereas the second baseband processor may be used to support any desired packet switched radio access technology.

Abstract: Methods and apparatuses to use multiple receivers of a wireless communication device for fast return to a first network from a second network after termination of a Circuit Switched Fallback (CSFB) voice call is disclosed. A first receiver of the wireless communication device is used to process the CSFB voice call on the second network, while a second receiver of the wireless communication device is used to determine a strongest suitable cell available on the first network, while the voice call is active. A strongest suitable cell is instantly available to the wireless communication device after the CSFB voice call ends. In some embodiments, the first network is an LTE network, and the second network is a legacy network.

The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle, the specification indicating when a plurality of onDurations of the C-DRX cycle occurs, the onDurations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the onDurations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the onDurations. In one embodiment, the data is raw audio data and the data packets are audio packets.

Abstract: Avoiding conflicts between radio access technologies (RATs) in a device configured to operate according to multiple RATs. The device may be operated in a discontinuous reception (DRX) mode according to each of a first RAT and a second RAT using a shared radio. It may be determined that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs. A subscriber identity of the device may be changed in response to determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs.

Abstract: A methodology for determining a periodicity of a neighbor cell search for a cellular mobile device is disclosed. The neighbor cell searches may be conducted during discontinuous reception (DRX) paging cycles. However, instead of performing a neighbor cell search during each DRX paging cycle, the period for performing a neighbor cell search may be adaptively determined. Various metrics may be used in determining the periodicity for neighbor cell searches. In various embodiments, two or more metrics may be utilized in combination to determine the neighbor cell search periodicity.
