    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, by dynamically adjusting priority between the two protocols. The wireless communication device may typically favor a first protocol (e.g. Bluetooth/BTLE), prioritizing resource requests by the first protocol. In certain use cases, the first protocol may demand high resource usage for an extended time, particularly for newer tracking and wearable devices, such as location tags, watches, headsets, etc. Such applications can disrupt existing use cases for a second protocol (e.g., Wi-Fi). Therefore, the wireless communication device may dynamically determine whether the second protocol is performing critical operations, such as latency-sensitive applications or high-performance operations. If so, the wireless communication device may allocate resources accordingly in real time, e.g., by reducing or limiting the resources assigned to the first protocol, to allow increased resources for the second protocol.
