Abstract
Described herein is an implantable medical device (IMD) that wirelessly communicates another IMD, and methods for use therewith. Such a method can include receiving one or more implant-to-implant (i2i) communication signals from the other IMD using a communication receiver of the IMD, measuring a strength of at least one of the one or more received i2i communication signals or a surrogate thereof, and updating a strength metric based on the measured strength or surrogate thereof. The method further includes determining, based on the updated strength metric, whether to increase, decrease, or maintain the sensitivity of the communication receiver of the IMD, and responding accordingly such that the sensitivity is sometimes increased, sometimes decreased, and sometimes maintained. The method can also include selectively causing a transmitter of the IMD to transmit an i2i communication signal to the other IMD requesting that the other IMD adjust its transmission strength.
