Abstract
Methods and apparatus, including computer program products, are provided for energy efficient communication based on feedback. A method may include sending a first message carried by a first wireless radio channel at a first predetermined energy level; receiving, in response to the first message, a second message carried by a second wireless radio channel; comparing the first message to the second message; sending a termination message, when the comparing indicates the first message and the second message match; and sending a portion of the first message at a second predetermined energy level, when the comparing indicates the second message contains at least one error when compared to the first message.
Claims20
A method comprising:
- sending at a first predetermined energy level a first message carried by a first wireless radio channel;
- receiving, in response to the first message, a second message carried by a second wireless radio channel;
- comparing the first message to the second message;
- sending a termination message, when the comparing indicates the first message and the second message match;
- and
- sending a portion of the first message at a second predetermined energy level, when the comparing indicates the second message contains at least one error when compared to the first message.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one processor, the at least one memory, and the computer program code configured to cause the apparatus to at least:
- send at a first predetermined energy level a first message carried by a first wireless radio channel;
- receive, in response to the first message, a second message carried by a second wireless radio channel;
- compare the first message to the second message;
- send a termination message, when the comparing indicates the first message and the second message match;
- and
- send a portion of the first message at a second predetermined energy level, when the comparing indicates the second message contains at least one error when compared to the first message.
A non-transitory computer-readable medium encoded with instructions that, when executed by at least one processor, cause operations comprising:
- sending at a first predetermined energy level a first message carried by a first wireless radio channel;
- receiving, in response to the first message, a second message carried by a second wireless radio channel;
- comparing the first message to the second message;
- sending a termination message, when the comparing indicates the first message and the second message match;
- and
- sending a portion of the first message at a second predetermined energy level, when the comparing indicates the second message contains at least one error when compared to the first message.
