摘要： Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.

摘要： A mobile computing device is configured to dynamically aggregate wireless communications on a common antenna. The device determines that a WiFi communication in a first frequency band is associated with an antenna, the WiFi communication having a number of assigned transmission time slots. The device determines that a second wireless communication in a second frequency band also is associated with the antenna, and determines a periodicity and/or a media quality of the second wireless communication. Based on the periodicity and/or media quality of the second wireless communication, the device aggregates the WiFi communication and the second wireless communication, the aggregation comprising assigning a number of packets of the second wireless communication to an aggregation frame of a plurality of frames associated with the transmission time slots assigned to the WiFi communication.

摘要： A device may store a plurality of different coexistence profiles for different possible communication scenarios. The device may be initialized with a first one of the coexistence profiles, and may operate to dynamically switch to different ones of the coexistence profiles based on current conditions. Each coexistence profile may include a number of coexistence related parameters stored as a plurality of data structures. During device use, the device may dynamically select an appropriate coexistence profile based on the current communication conditions, such as Wi-Fi RSSI, Bluetooth RSSI, and/or the number of Wi-Fi and/or Bluetooth devices with which communication is currently occurring, among other possible factors. The coexistence profile is selected to provide the best possible Wi-Fi and/or Bluetooth output performance based on current conditions. The device may repeatedly dynamically select different coexistence profiles as conditions change, e.g., may select different coexistence profiles on a second or even millisecond basis.

摘要： Methods and apparatus for mitigating the effects of interference between multiple air interfaces located on an electronic device. In one embodiment, the air interfaces include a WLAN interface and PAN (e.g., Bluetooth) interface, and information such as Receiver Signal Strength Index (RSSI) as well as system noise level information are used in order to intelligently execute interference mitigation methodologies, including the selective application of modified frequency selection, variation of transmitter power, and/or change of operating mode (e.g., from multiple-in multiple-out (MIMO) to single-in, single-out (SISO)) so as to reduce isolation requirements between the interfaces. These methods and apparatus are particularly well suited to use cases where the WLAN interface is operating with high data transmission rates. Business methods associated with the foregoing technology are also described.

摘要： Methods and apparatus for selectively switching one or more antennas in a multiple-input, multiple-output (MIMO) antenna array so as to mitigate interference with another RF interface within the same space-constrained device, based on radio frequency isolation. In one embodiment, the MIMO interface comprises a WLAN interface having a 2×2 or 3×3 array of antennae which are placed in a wireless device in an asymmetric fashion with respect to the antenna of the second interface, and the other interface comprises a PAN (e.g., Bluetooth) interface operating in an overlapping frequency band (e.g., ISM band). When both interfaces are operating, interference is mitigated through selectively switching off one or more of the MIMO antennae, and using the remaining antenna(e) having the best isolation from the Bluetooth antennae. This approach allows simultaneous operation of both interferences without significant degradation to user experience or the operation of either interface, and may also provide power savings critical to mobile device battery longevity.

摘要： A method for handling received packets is described. The method includes receiving a packet over a wireless connection, determining whether the packet is received within a reordering window, the reordering window defining a window size to receive data, when the packet is received outside the reordering window, determining whether the packet is a transmission control protocol (TCP) packet and when the packet is a TCP packet, delivering the TCP packet to a TCP/Internet Protocol (IP) stack.

摘要： Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, using a shared antenna, e.g., due to limitations resulting from a small form factor of the wireless communication device. The wireless communication device may determine whether communications according to a second protocol are causing performance of communications according to a first protocol to fall below a threshold level. If so, the wireless communication device may operate in a mode that favors communications according to the first protocol. If not, the wireless communication device may operate in a mode that favors communications according to the second protocol. For example, the mode that favors communications according to the first protocol may include temporarily implementing operations to remedy the poor performance of the communications according to the first, e.g., periodically, until the performance of the communications according to the first protocol recovers.

摘要： 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.
