COEXISTENCE INTERFACE AND ARBITRATION FOR MULTIPLE RADIOS SHARING AN ANTENNA
First Claim
1. An apparatus comprising:
- a first serial bus conductor over which first serial information is communicated onto the apparatus; and
a second serial bus conductor over which second serial information is communicated out of the apparatus, wherein one of the first and second serial information includes a wireless coexistence transmit request and communication system state information, and wherein the other of the first and second serial information includes a grant of the transmit request.

Abstract
A serial coexistence interface between two radio devices is involved in arbitrating access to an antenna. The serial interface involves messages that are sent from one radio to the other radio. Serial messages communicated across the same conductor can communicate: 1) timing-precise antenna arbitration and control information, and 2) communication system state information. Examples of antenna arbitration timing-precise information include a request to use the antenna and a corresponding grant or no grant response. Communication system state information, on the other hand, is not involved in the carrying out of the mechanics of the packet-by-packet arbitration for the antenna, but rather is higher level system information usable to make higher level decisions about the arbitration strategy used. Communication system state information may include an indication of a button press, an indication of a user action, or a change in the operational mode of the higher level communication system.

26. An apparatus comprising:
-
a serial bus conductor; and a Universal Asynchronous Receiver/Transmitter (UART) operatively coupled to the serial bus conductor, wherein a single serial message is communicated across the serial bus conductor, and wherein the single serial message is a wireless transceiver coexistence message and includes;
