    Abstract: The disclosed embodiments provide a system that processes network packets. Upon receiving a first Transmission Control Protocol (TCP) header for a first TCP segment from a network link, the system immediately provides a portion of the first TCP header to a transport layer prior to receiving all payload data for the first TCP segment. Next, the system uses the transport layer to transmit a first acknowledgment of the first TCP segment to the network link, wherein the first acknowledgment reduces a round-trip time (RTT) associated with the first TCP segment.

    Abstract: In the subject system for Bluetooth audio role-based scheduling, an electronic device (e.g., a mobile phone), may receive streaming audio over a cellular connection, e.g. LTE, and may stream the audio to a head unit of a vehicle, e.g. via Bluetooth. The electronic device may also concurrently communicate with other electronic devices via, e.g., Wi-Fi, Bluetooth, and/or BTLE. The electronic device may determine the Bluetooth/communication capabilities of the HU device, such as buffer size, and the electronic device may proactively configure Bluetooth settings/parameters for communicating with the HU device based on the capabilities of the HU device. The electronic device may also adaptively modify scheduling for communications with other electronic devices based on the determined capabilities of the HU device. In this manner, the electronic device can proactively mitigate and/or prevent the sub-optimal user experience caused by any differences in Bluetooth/communication capabilities of the HU device and the electronic device.

    Abstract: Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

    Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

    Abstract: An electronic device uses one antenna to wirelessly communicate information with two different wireless networks via concurrent connections associated with different radio access technologies. More specifically, the electronic device may receive video via a first of the connections using a multicast communication protocol. In order to maintain the second connection, the electronic device may switch, for a time interval, from the first connection to the second connection during switching events. This switching can disrupt displayed content associated with the video. To prevent this disruption, in response to a trigger that warns of an upcoming switching event, the electronic device accesses a portion of the video in a buffer during the time interval associated with the switching event. When the communication circuit switches back to the first connection after the switching event, the electronic device reverts to the video communication using the multicast communication protocol.

    Abstract: Carrier aggregation using unlicensed frequency bands. A primary carrier for communication between a base station (BS) and a wireless user equipment (UE) device may be configured according to a first wireless communication technology. The primary carrier may be on a licensed frequency band. A secondary carrier for communication between the BS and the UE may also be configured according to a first wireless communication technology. The secondary carrier may be on an unlicensed frequency band. Channel conditions for each of multiple possible channels of the unlicensed frequency band may be assessed according to a second wireless communication technology as part of configuring the secondary carrier.
