Patent ID: 11469856

Abstract:
When a received message is found to be corrupted in 5G or 6G, the receiver can request a retransmission. If only one message element is faulted, retransmitting the whole message may be a waste. Procedures are disclosed for the receiver to determine which message elements are likely faulted by measuring the modulation quality, based on how far each message element's modulation deviates from the states of the modulation scheme. The receiver can then indicate, in an acknowledgement for example, which portion of the message needs to be retransmitted. After receiving that retransmitted portion, the receiver can then produce a merged version by substituting the retransmitted portion in the as-received message, or can select the best-quality elements from the two versions for the merged copy, and thereby eliminate most or all of the faults. Networks supporting these protocols may have fewer delays, faster responses, improved reliability, and reduced resource usage by avoiding unnecessary retransmission volumes, thereby providing improved service to network users, according to some embodiments.
