Abstract: Methods, systems, and devices for wireless communications are described. Cyclic redundancy check (CRC) bits may be appended to a set of information bits on a per-group basis prior to encoding using an error correcting code. The amount of CRC bits appended to each group of information bits may be based on the priority of the group of information bits. For example, the priority may be based on the type of information conveyed by the group of information bits. For example, for a video stream, information bits conveying low frequency information may have a higher priority than information bits conveying high frequency information, as the low frequency bits may be more important to user perception/experience of the video. The transmitting device and the receiving device may negotiate the CRC configuration (e.g., the CRC bits per-group and the locations of the groups) so that the receiving device can verify the information bits.

Abstract: Message faults are caused by network crowding and signal fading at high frequencies of 5G and 6G. Current error-detection and correction algorithms are computationally demanding, especially for new low-cost reduced-capability IoT devices. Disclosed are methods for (a) determining whether a message is faulted using a compact error-detection code, (b) localizing the most likely faulted message element(s) according to the waveform signal, and (c) determining the likely corrected version by back-calculating from the error-detection code. Other versions include testing various modulation substitutions for the most suspicious message elements, having the worst signal quality. The waveform parameters may include a deviation from an average amplitude, phase, frequency, or polarization, as well as an amount of amplitude variation and phase variation within the message element. Identification of the most likely faulted message elements may enable recovery of the message without a costly retransmission.

A number of the known information data bits depends on a number of the information data bits such that the first code rate is fixed regardless of the number of the information data bits.

Abstract: Systems and methods are disclosed herein that provide low latency data communication with improved physical link layer reliability through repeated physical layer retransmission of data over a data connection whenever the connection is idle (i.e., no new data to send). In some embodiments, the transmission of administrative control symbols (e.g. “idles,” “commas”, etc.) can be suppressed or otherwise reduced to allow some of the available connection bandwidth to be used for data redundancy and fault tolerance through the repeated retransmission of data as described in more detail below. Accordingly, instead of executing time-consuming error correcting routines, a receive node can discard the erroneous data frame and process at least one repeat frame that carries the same data payload. Sequence numbers and/or other repeat indicators can be used to distinguish original frames from repeat frames and/or for identifying which frames carry the same data payload.

The feedback may be a NAC that includes a first quantity of bits configured for indicating an existence of an error and a second quantity of bits configured for indicating the error cause. A format of the NAC frame may include bits configured to identify multiple types of error causes associated with the different layers of the protocol stack.

Abstract: A radio communication link is established between first and second nodes in a cellular network, which comprise at least channel coding and decoding of first and second Physical (PHY) layers and first and second Medium Access Control (MAC) sublayers. User data is transmitted from the first node to the second node while applying a PHY Forward Error Correction (FEC) algorithm in transmission for coding and in reception for decoding by the first and second PHY layers. A value of a PHY-FEC error metric is computed with respect to errors in the user data received by the second node that are uncorrected by the PHY FEC algorithm. The received user data including the uncorrected errors is transferred from the second PHY layer to the second MAC sublayer, subject to the value of the PHY-FEC error metric being less than a threshold used by an error tolerance procedure.
