Adaptable communication sensitivity for an implantable medical device

A communication method for an implantable medical device, comprising:

• intermittently sensing radio frequency energy;
• generating a sample set comprising a defined number of energy sample values, wherein the enemy sample values indicate a plurality of enemy levels of the intermittently sensed radio frequency energy;
• determining a maximum energy level for the sample set based on identification of at least one of the energy sample values having a higher value than at least one other one of the energy samples values;
• and
• adapting a threshold based on the maximum energy level, wherein the adaptation of the threshold adjusts detection sensitivity associated with identifying target radio frequency signals in a current environment.

An implantable medical apparatus, comprising:

• a receiver configured to intermittently sense radio frequency energy, and configured to generate a sample set comprising a defined number of energy sample values, wherein the energy sample values indicate a plurality of energy levels of the intermittently sensed radio frequency energy;
• a sample processor configured to determine a maximum energy level for the sample set based on identification of at least one of the energy sample values having a higher value than at least one other one of the energy sample values;
• and
• a threshold adapter configured to adapt a threshold based on the maximum energy level, wherein the adaptation of the threshold adjusts detection sensitivity associated with identifying target radio frequency signals in a current environment.
