20. A system comprising:
a first wireless communication device; and
a second wireless communication device coupled to the first wireless communication device via a 3-wire interface, wherein:
the first wireless communication device shares a wireless transmission medium with the second wireless communication device;
the first wireless communication device is configured to:
transmit a request to use the wireless transmission medium, to the second wireless communication device via the 3-wire interface;
transmit timing data to the second wireless communication device via the 3-wire interface; and
in response to receiving an authorization to use the wireless transmission medium, transmit data using via the wireless transmission medium; and
the second wireless communication device is configured to:
receive, from the second wireless communication device, the request to use the wireless transmission medium;
receive, from the second wireless communication device, the timing data;
determine a time period to allow the second wireless communication device to use the wireless transmission medium based on the timing data; and
in response to determining the time period, transmit, to the second wireless communication device, the authorization to use the wireless transmission medium.
