Abstract: A method and apparatus for coordinating communications between a Bluetooth system and a WiFi system in a device. Requests for airtime are collected from the Bluetooth system and the WiFi system. A local slot availability mask is prepared showing time slots allocated to the Bluetooth system. The local slot availability mask is forwarded to the WiFi system so that the WiFi system may avoid sending and receiving WiFi wireless communications during time slots allocated for Bluetooth system use. The WiFi system may override the Bluetooth allocation when needed. Changes in priority of the Bluetooth communications and of the WiFi communications result in changes in allocation of time slots.

Abstract: A short range radio communication device and a method of controlling a short range radio communication device may include a processing circuit configured to: determine a time offset between an initial starting point of operation of a transceiver in accordance with a first frequency hopping sequence and a shifted starting point of operation of the transceiver in accordance with the first frequency hopping sequence so that a first segment of a frequency range is exclusive of a second segment of the frequency range; and control at least one of a controller and a clock circuit to operate the transceiver in accordance with the first frequency hopping sequence at the shifted starting point.

Abstract: Methods, devices and systems for dynamic scheduling of Wi-Fi or Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Wi-Fi or Bluetooth can perform coexistence decisions including Wi-Fi and Bluetooth channel or Adaptive Frequency Hopping (AFH) selection based on modem calculated Rx or Tx indications and device geo location, maximum allowed transmit power per channel for Wi-Fi, and the LTE modem connection state.

Abstract: Embodiments pertain to systems, methods, and component devices for Tx-Tx transmit concurrency by combining signals before power amplification. One example embodiment includes validity check circuitry configured to check a transmission power for a Bluetooth signal against a first threshold transmission power, a Bluetooth Power Amplifier, and a WLAN power amplifier. A switching network controlled by the validity check circuitry and configured to couple the Bluetooth input to Bluetooth power amplifier input when the transmission power for the Bluetooth signal is above the first threshold transmission power and to couple the Bluetooth signal with a WLAN signal for input to the shared WLAN power amplifier when the transmission power for the Bluetooth signal is less than the first threshold transmission power.

Abstract: Techniques for employing channel inhibition (CI) with adaptive frequency hopping (AFH) in connection with Bluetooth (BT) are discussed. One example system employing such techniques comprises a BT master component operating on a plurality of channels via AFH; and a processor configured to: assign, based on a set of criteria, a first (e.g., ‘UNUSED’) status and a priority level to one or more channels, and a second (e.g., ‘USED’) status to each other channel; determine whether a total number of channels set as ‘USED’ is less than a minimum number of required channels; and in response to a determination that the total number of channels set as ‘USED’ is less than the minimum number, repeatedly assign a ‘USED’ status to a channel having a lowest priority level among channels with the ‘UNUSED’ status, until the total number of channels set as ‘USED’ equals the minimum number.
