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.
