Fault correction by the receiver in 5g and 6g communications

Abstract

In 5G-Advanced, and especially 6G, message faulting is expected to be a major impediment due to phase noise and increased pathloss attenuation, as well as network crowding. Therefore, new procedures are disclosed enabling the receiver to identify and correct message faults without a retransmission and without using bulky FEC (forward error correction) bits. For example, the receiver can measure the 'distance' of each received message element from the nearest modulation state, and thereby quantify the modulation quality, or suspiciousness, of each message element. To correct the message, the worst-modulated ones can be altered first, generally selecting the next-closest states since small distortions are more likely than large distortions. The result: rapid message recovery, internal to the receiver processor, without adding to the message size or the latency.
