Techniques to improve co-existence among multiple radios
First Claim

1. A method performed by a wireless communications device, the method comprising:
- requesting no transmission by a first radio for a first type of wireless communication during a first time region; and
selectively adjusting a beginning of a time slot of a frame transmitted by a second radio based on one or more preambles of frames from a third radio for a third type of wireless communication while permitting simultaneous transmission of second and third radio frames, and the second radio providing a second type of wireless communication.

Abstract
Techniques are described that can be used to permit coexistence of different radios. Preambles of frames from a first radio are detected. If the preambles occur within a prescribed period of one another, then a frame synchronization signal is transmitted. Based on the timing of the frame synchronization signal, a second radio adjusts the timing of transmit and receive time slots.
