Error correction by merging copies of 5G/6G messages
Disclosed are procedures for measuring the modulation quality of each message resource element in a failed 5G or 6G communication, thereby revealing the most likely fault locations in the message. The types of modulation deviations in the low-quality message elements can provide further guidance as to the correct demodulation. In addition, after receiving a second copy, the copies can be merged by selecting the highest quality message elements from each version, where the quality is related to how far each message element's modulation deviates from the calibrated “states” of the modulation scheme. The receiver may also determine directional information based on the modulation of each message element, and may compare versions to determine the most likely correct state of each message element. Such strategies may directly recover the original message, or may greatly reduce the number of variations that need to be tested. When implemented, fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.
1. A method for correcting a fault in a wireless message, comprising:
receiving a first copy of the message and determining that the first copy is corrupted;
then receiving a second copy of the message and determining that the second copy is corrupted;
determining, for each message element of the first and second copies, a modulation quality according to a difference between a modulation of the message element and a modulation level of a modulation scheme; and
creating a merged message by selecting, for each message element of the merged message, from the corresponding message elements of the first and second copies, whichever message element has higher modulation quality;
wherein the modulation of the message element comprises a first amplitude value or a first phase value or both, the modulation level of the modulation scheme comprises a second amplitude value or a second phase value or both, and the modulation quality of the message element comprises a difference between the first and second amplitude values, or a difference between the first and second phase values or both.
2. The method of claim 1 , further comprising:
determining one or more sectors according to an amplitude modulation or a phase modulation or both; and
determining, according to each sector, a direction comprising an alteration in amplitude modulation or phase modulation or both.
3. The method of claim 2 , further comprising:
altering a message element of the merged message according to the direction; and
determining whether the merged message, so altered, is corrupted.
4. The method of claim 1 , wherein the selecting comprises comparing the modulation quality of a particular message element of the first message to the modulation quality of the corresponding message element of the second message, and selecting whichever of the compared message elements has a higher modulation quality.
