Enhanced reliability by waveform analysis in 5G/6G communications
Corrupted messages in 5G and 6G are usually discarded, leading to a retransmission with its added costs, delays, and background generation. Therefore, disclosed herein are methods for a wireless receiver to determine which message elements are faulted, and in many cases to correct them, based on parameters of the waveform signal in each message element. Multiple parameters may be combined for better sensitivity to the fault condition. For example, the indicator parameters may be the modulation deviation of each message element, its amplitude or phase noise level, characteristic interference patterns between symbol-times, a polarization anomaly, a frequency offset, or combinations of these. After localizing the likely faulted message elements, the receiver may be able to recover the message by correcting the waveform signal or the demodulation value, thereby saving time and energy at near zero cost.
Coded sidelink feedback for improved reliability
Methods, systems, and devices for wireless communications are described herein. A user equipment (UE) may generate a set of feedback bits corresponding to sidelink messages received via one or more sidelink channels. The UE may transmit a first sidelink message via a first feedback resource of a physical sidelink feedback channel occasion. The first sidelink message may include a first subset of the feedback bits. The UE may transmit at least two additional sidelink feedback messages via respective feedback resources. The first additional sidelink feedback message may include the first subset of feedback bits and a second subset of feedback bits encoded using an erasure coding function.
Autonomous Fault Mitigation Based on Waveform Signatures in 5G/6G
Message faulting is the leading cause of poor reception. Currently, most faulting in 5G and 6G requires either transmission of bulky FEC bits, or retransmission of the message, at substantial delay and cost. This paper shows how the receiver can internally (autonomously) correct the message faults by scanning the digitized waveform signals, to detect characteristic fault signatures that clearly identify the likely faulted subcarriers. With that information, and the CRC or other appended code, and optionally an AI assist, the receiver can correct the message in a fraction of the time required for a retransmission. The message is corrected instantly, with zero background generation, zero bandwidth consumption, and zero cost. Autonomous fault mitigation in the receiver is the most efficient way to improve user reception.
Network coding for multi-link device networks
Certain aspects of the present disclosure provide a method of wireless communications by a first multi-link device (MLD).
