System and method for sharing a common communication channel between multiple systems of implantable medical devices
First Claim
1. A method of enabling a plurality of systems to communicate over a common communication channel wherein each system is configured to enable communication during periodic and temporally contiguous frame periods determined asynchronously by each said system and having occupied temporal portions of each said frame period comprised of transmission communication periods dedicated to each system and wherein each said frame period has a start and an end that spans the entire temporal bandwidth of said common communication channel, said method comprising the steps of:
- transmitting during each said frame period at least one beacon message having a unique heavily-coded beacon marker code portion;
receiving beacon messages by said systems according to said heavily-coded beacon marker code portions from other said systems that are within communication range; and
processing two or more of said received heavily-coded beacon marker code portions of said beacon messages to thereby determine the start of the frame period of another one of said systems.

Abstract
A system and method that facilitates multiple systems of communicating devices, i.e., a master device and one or more implantable slave devices, to coexist on a common, e.g., RF, communication channel having a limited temporal bandwidth while maintaining the required update rate between each master device and its associated slave devices. In embodiments of the present invention, master devices periodically transmit one or more beacon messages that are suitable for identification by other such master devices at a communication range greater than the communication range that may cause interference between systems and thus enabling one or more systems to cause the position of its frame periods to be interleaved with the frame periods of other such systems in anticipation of systems moving in closer proximity and actually interfering with each other.
