Mitigating false messaging in leadless dual-chamber pacing systems and other IMD systems
First Claim
1. For use by an implantable medical device (IMD), a method for reducing how often the IMD accepts false messages, the method comprising:
- receiving a message;
measuring a message interval indicative of a length of time between when the message was received and when a preceding message was received;
determining, based on the measured message interval, whether the message was received within a message window;
determining whether to reject the message based on results of the determining whether the message was received within the message window; and
adjusting a temporal position of the message window based on the measured message interval.

Abstract
Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and measuring a message interval indicative of a length of time between when the message was received and when a preceding message was received. The method can also include determining, based on the measured message interval, whether the message was received within the message window, and determining whether to reject the message based on results thereof. The method can also include adjusting a temporal position of the message window based on the measured message interval. The method can further include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.

-
receiving a message; measuring a message interval indicative of a length of time between when the message was received and when a preceding message was received; determining, based on the measured message interval, whether the message was received within a message window; determining whether to reject the message based on results of the determining whether the message was received within the message window; and adjusting a temporal position of the message window based on the measured message interval. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. An implantable medical device (IMD), comprising:
-
at least one receiver configured to receive messages; at least one of a processor or controller configure to measure a message interval indicative of a length of time between when a message was received and when a preceding message was received; determine, based on the measured message interval, whether the message was received within a message window; determine whether to reject the message based on whether the message was received within of the message window; and adjust a temporal position of the message window based on the measured message interval. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. For use by an implantable medical device (IMD), a method for reducing how often the IMD accepts false messages, the method comprising:
-
receiving a message; determine whether the message was received within a message window; determining that the message should be rejected if the message was not received within the message window; determining that the message should not be rejected if the message was received within the message window; adjusting a temporal position of the message window based on when the message was received; after the temporal position of the message window has been adjusted receiving a further message; determining whether the further message was received within the message window; determining that the further message should be rejected if the further message was not received within the message window; and determining that the message should not be rejected if the message was received within the message window.

22. For use by an implantable medical device (IMD), a method for reducing how often the IMD accepts false messages, the method comprising:
-
receiving a message; determine whether the message was received within a message window; determining that the message should be rejected if the message was not received within the message window; determining that the message should not be rejected if the message was received within the message window; performing error detection and correction on the message; determining a quality measure indicative of at least one of a quality of the message or a quality of a channel over which the message was received; and determining whether to reject the message based on the quality measure.
