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: A method is provided. The method includes attaching a user device to a wireless network via a router of a first communications protocol. The method includes determining, based on information about a second session using a second communications protocol, a first time window and a second time window. The method includes determining to perform a first session using the first communications protocol in the first time window. The method includes performing a first arbitration between the first session and the second session. The method includes determining, based on the first arbitration, that the first session has a priority over the second session in the second time window. The method includes performing a second arbitration between the first session and a third session using a third communications protocol. The method includes determining, based on the second arbitration, whether to perform the first session in the second time window.

Abstract: In embodiments, a client station operates to identify and prioritize time-sensitive short-range wireless packets, such as time-sensitive Bluetooth Low Energy (BTLE) packets, in a congested wireless environment. The client station may identify time-sensitive packets using, e.g., the type of device providing the packets, a state of the device providing the packets, and/or the type of data included in the packets. The client station may prioritize the time-sensitive packets in various ways, including by providing priority scheduling to the time-sensitive packets; pausing communication of other types of Bluetooth packets, such as A2DP packets; reducing a data rate of other types of Bluetooth packets, such as A2DP packets; and/or extending a data packet size of time-sensitive BTLE packets. The time-sensitive packets may thus be prioritized over packets associated with the same wireless protocol and/or a different wireless protocol.

Abstract: Apparatus and methods for rapid, cost effective testing of wireless systems. In one embodiment, a unit under test (UUT) is tested by a test “server”. The UUT and test server communicate via a “connectionless” protocol which is based on beacons (and beacon responses) which can carry one or more test primitives. The aforementioned “connection-less” test protocol can be performed without wireless network configuration, which greatly reduces test time, Additionally, exemplary solutions are presented for “lock-up” of the UUT and the test server.

Abstract: Methods and apparatuses for mitigating coexistence interference in a wireless device between a WLAN interface and a WPAN interface during a WLAN authentication process. The wireless device associates with a WLAN access point (AP), and after receiving a WLAN association response from the WLAN AP, the wireless device alternates between WLAN time periods, during which WLAN transmission is enabled and WPAN transmission is disabled, and WPAN time periods, during which WPAN transmission is enabled and WLAN transmission is disabled, during the WLAN authentication process. Durations of the WPAN time periods are based at least in part on a WPAN profile, e.g., a Bluetooth profile, in use by the wireless device. Durations of the WLAN time periods are based at least in part on receipt of WLAN authentication messages from the WLAN AP during the authentication process or expiration of WLAN authentication process timers.
