Disclosed is a method to demodulate messages according to two different modulation schemes in 5G and 6G, and thereby identifying which message elements are likely faulted. The two modulation schemes are QAM in which the signal is a sum of two orthogonal amplitude-modulated “branch” signals, and classical amplitude-phase modulation in which each message element's raw signal is both amplitude and phase modulated. The two schemes have similar information density but different noise sensitivities. Therefore, a receiver can compare the demodulated message using one modulation scheme to the same message demodulated according to the other modulation scheme, and flag any message elements that demodulate differently. In addition, one modulation scheme may be more effective than the other depending on conditions.

A method of wireless communication at a user equipment (UE) includes receiving, from a network node, a message indicating slots for transmitting a transport block on a physical uplink shared channel (PUSCH). The method also includes segmenting the transport block into code blocks. The method further includes encoding the code blocks to produce encoded code blocks. Each code block may be encoded at a coding path from a group of coding paths associated with a coding chain. The method still further includes transmitting the encoded code blocks in the slots on the PUSCH.

A communication method is configured to increase speed of messages reception over a bandwidth limited channel such as high frequency (HF) radio. User data arriving from a high-speed network is transformed into a format suitable for transmission over the radio channel. Message packets that will take longer to reach a destination via the radio channel as compared to alternative channels, such as a fiber optic network, are rejected for radio transmission. When the packet is received, the receiver deduces message length by using information from various error handling techniques, such as forward error correction (FEC) and cyclic redundancy check (CRC) techniques. Fill data is transmitted between message packets when no data is available. The FEC and CRC information for the fill data is modified so that the fill data will fail FEC and CRC checks at the receiving station.

With rapid increases in the number and spatial density of wireless messages as 5G and 6G are rolled out, it is essential that improved methods for fault-tolerant demodulation and error mitigation be developed. Disclosed herein are methods for receiving a message concatenated with a demodulation reference, determining the predetermined modulation levels of a modulation scheme, and demodulating the message by measuring the amplitude mad/or phase modulation values of each message element. The measured modulation values are then compared with the predetermined modulation levels of the modulation scheme to demodulate the message. Importantly, the message can be demodulated by determining an amplitude and phase of the raw signal for each message element, or by separating the raw signal into two orthogonal “branches” and determining the amplitudes of the two branches. By demodulating the message both ways, message faults may be identified and mitigated, according to some embodiments.
