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.

Abstract: In 5G-Advanced and especially 6G, a primary concern is the increase in message faulting due to higher pathloss and phase noise at FR2 frequencies. Current methods for dealing with faults include packing the message with bulky error-correction (FEC) bits which are often ineffective, or automatically requesting a costly retransmission. As a substantially better alternative, the receiver may identify the specific fault locations and attempt an immediate repair by testing the modulation quality of each message element. For example, for a QAM-modulated message, the receiver can measure the I and Q branch deviations relative to predetermined levels, and the message element(s) with largest deviations is/are likely faulted. Alternatively, if the message is advantageously modulated according to the waveform amplitude and phase, the receiver can determine the amplitude and phase deviations relative to predetermined values. An AI model can greatly assist in the fault localization and in finding the corrected values.

Abstract: A central challenge in next-generation 5G/6G networks is achieving high message reliability despite very dense usage and unavoidable signal fading at high frequencies. To provide enhanced fault detection, localization, and mitigation, the disclosed procedures can enable an AI model (or an algorithm derived from it) to discriminate between faulted and unfaulted message elements according to signal quality, modulation parameters, and other inputs. The AI model can estimate the likelihood that each message element is faulted, and predict the most probable corrected value, among other outputs. The AI model can also consider the quality of a demodulation reference used to demodulate the message, and the quality of the associated error-detection code. The AI model can also consider previously received messages to the same receiver, or messages of a similar type. Fault mitigation by the receiver can save substantial time and resources by avoiding a retransmission. Many other aspects are disclosed.

Abstract: Message reliability is a key requirement of 5G/6G communications. In many challenging network environments, two successive retransmissions of a message can both be corrupted, greatly reducing reliability. Therefore, methods are disclosed for identifying faulted message elements according to a metric that includes the waveform or SNR of the message element, its modulation quality, and a consistency check between the received versions. The receiver can then assemble a merged message version by selecting the higher quality version of each message element from the two (or more) corrupted versions, and thereby avoid requesting yet another retransmission. In addition, the receiver can monitor the background level and, if it is above a predetermined limit, can request that the receiver store the message for a predetermined time, or until the background level subsides below the limit.
