US Patent 11522636 Modulation quality and fault mitigation in 5G/6G

Prior art includes error detection according to an embedded CRC (cyclic redundancy code) or the like, and error correction using FEC (forward error correction) codes, but achieves only partial success in practice, leading to frequent requests for message retransmission. Disclosed is a method for detecting errors in individual message elements using 5G or 6G technologies, by measuring the modulation quality according to how far the amplitude or phase of the message element deviates from the calibrated modulation levels of the modulation scheme. A large deviation indicates a faulted message element, whereas a close match with the calibrated modulation levels is likely correct. By identifying faulted message elements individually, the receiver can recover the message using a number of strategies, disclosed herein. With improved error detection, and localization to individual message elements, network communications can be substantially upgraded at negligible cost, according to some embodiments.
