    Abstract: Circuits, methods, and apparatus that can allow chipsets in an electronic device to share information such that they can more efficiently utilize resources that are available in the electronic device. One example can provide a bus that is shared by three or more chipsets in an electronic device. This shared bus can be used by the chipsets in the electronic device to communicate and negotiate for the utilization of resources of the electronic device.

    Abstract: A method for offloading a video portion of a video call form a cellular network to a WLAN is provided. The method can include a wireless communication device participating in a video call with a remote device over a connection between the wireless communication device and a cellular network. The video call can include a first video stream carried over a first bearer on the cellular network and an audio stream carried over a second bearer on the cellular network. The method can further include the wireless communication device establishing a connection between the wireless communication device and a WLAN; performing a call setup procedure with the remote device to establish a second video stream over the WLAN; terminating the first video stream; and using the second video stream and the audio stream to continue the video call.

    Abstract: A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.

    Abstract: A method for redundant transmission of real time data is provided. The method can include an edge node in a wireless network sending a first RTP packet including a first real time data frame to a second edge node. The method can further include the edge node determining that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node. The method can additionally include the edge node, in response to determining that the radio link condition is sufficient to support redundant transmission of real time data, bundling the first real time data frame with a next sequential real time data frame that has not been previously sent to the second edge node in a second RTP packet at a PDCP layer of the edge node; and sending the second RTP packet to the second edge node.

    Abstract: A user equipment (UE) operating in a communication system comprising a base station and one or more UEs. The UE may be configured to operate on or “camp” on two different networks with one radio. In this exemplary system, the radio may be normally connected to the first network (NW1) and may from time to time be “tuned away” from NW1 to a second network (NW2). The UE may inform NW1 that it has tuned away to another network, e.g., using start and end indicators. This information may prevent NW1 from wasting downlink capacity by unnecessarily allocating downlink resources to the UE during the tune-away. Alternatively, or in addition, this information may prevent NW1 from penalizing the UE, e.g., by reducing its future downlink allocations, since the UE does not respond to NW1 commands during the tune-away.

    Abstract: This disclosure relates to performing antenna selection to reduce interference in a wireless device. According to some embodiments, it may be determined whether simultaneous communication according to first and second wireless communication technologies causes performance degradation to a third wireless communication technology. If the simultaneous communication according to first and second wireless communication technologies does cause performance degradation to the third wireless communication technology, selection of antenna(s) used for the communications may be based at least in part on the determination that the simultaneous communication according to the first and second wireless communication technologies causes performance degradation to the third wireless communication technology.
