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.

A coding method and apparatus for data communication are provided, and may be applied to a plurality of scenarios such as a metro network, a backbone network, and a data center interconnection. As an example method, a first codeword is formed, where the first codeword includes n image bits and n to-be-transmitted bits. The n image bits are selected from to-be-transmitted bits in m source codewords. The m source codewords are formed before the first codeword. Both n and m are positive integers, and n>m; The n to-be-transmitted bits in the first codeword are sent. The bit in the first codeword can be protected by a plurality of codewords generated at different moments. In addition, the bit in the codeword can be protected by different quantities of codewords.

A monitor is further included and is configured to monitor messages received at the TLRU and further configured to determine whether received messages are valid based on at least a portion of the set of expected messages stored in the memory. A plurality of RLRUs are further included and configured to receive message from the TLRU and to execute the instructions included in the received messages.

A mobile communication device is provided that includes a receiver configured to receive a signal.

A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter's processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.

A physical layer low power communication method and apparatus are provided. The physical layer low power communication method may include receiving a data packet from a transmitter, measuring a channel quality using a preamble and signal field information included in the data packet and determining whether recovery of the data packet is possible, calculating an error generation rate according to a determination result, and discarding the data packet and operating in a power save mode when the error generation rate is higher than a predetermined reference.

A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received packet, without having to perform full FEC decoding of the packet that could impair the overall latency of the system due to the time spent in a complete FEC decoding of the packet. In order to do that, it generates a decision variable with the aim to check whether a received packet has errors or not, after performing only partial FEC decoding of the packet, without either resorting to the use of error-detection codes.

A communication method is provided for a communication system comprising a transmitter and a receiver. The method involves communicating data from the transmitter to the receiver over a banded communication channel The method comprises: applying a forward error correction, FEC, code to data to be transmitted to obtain FEC-encoded data; assigning the FEC-encoded data into a plurality of sub-channels; modulating the data from each of the plurality of sub-channels into a corresponding one of a plurality of sub-bands, the plurality of sub-bands having spaced apart center frequencies; and concurrently transmitting the data from the plurality of sub-bands onto a banded communication channel, the banded communication channel comprising one or more pass-bands and one or more stop-bands.

An unsolved problem in 5G-Advanced and especially 6G is message fault mitigation without a costly retransmission. Methods are disclosed for the receiver to analyze each message element's received waveform signal to detect characteristic features of interference and noise, such as excessive amplitude or phase variation within the message element or excessive deviation from the predetermined modulation levels of the modulation scheme, and to provide that data to an AI model trained in message fault correction. The AI model can then identify the faulted message elements, and attempt to correct them according to the likely intent or meaning of the message based on the non-faulted message elements, and on the bit sequences of previously received non-faulted messages, and other criteria that the AI model may apply. By repairing the message upon receipt, the costs in time, transmission power, and background noise generation may be avoided. Next-generation users will enjoy the improved reception.
