Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transport block (TB), the receiving the TB including performing log likelihood ratio (LLR) calculations on one or more parts of the TB based at least in part on a determination that the TB is likely to fail a cyclic redundancy check (CRC). The UE may transmit an indication of the one or more parts of the TB for which the UE performed LLR calculations. Numerous other aspects are described.

A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE ma also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

A method reducing amount of memory utilized by hybrid automatic repeat request (HARQ) operations is disclosed. When an apparatus employing the method receives an LDPC encoded packet, the apparatus firstly estimates a signal quality value of the received packet, and performs an LDPC decoding algorithm on the received packet. If the received packet is not successfully decoded by the apparatus, the received and decoding-failed packet is compressed in order to reduce bit-width, and the compressed packet is stored in a memory device for later HARQ operations. The apparatus employing the method is also disclosed.

A faulted message element in 5G or 6G can often be identified according to its modulation parameters, including a large deviation of the branch amplitudes from the predetermined amplitude levels of the modulation scheme, and/or the SNR of the branch amplitudes, and/or an amplitude variation of the raw signal or the branches during the message element, and/or an inconsistency between the modulation state as determined by the amplitude and phase of the raw waveform versus the amplitudes of the orthogonal branch signals, among other measures of modulation quality. An AI model may be necessary to correlate the various quality measures, and optionally to determine the correct demodulation of faulted message elements. Costly, time-consuming retransmissions may be avoided by determining the correct demodulation of each message element at the receiver, thereby improving throughput and reliability with fewer delays.

Techniques for radio frequency uplink performance assessment utilizing downlink erasure frame analysis are provided. An indication of if a received frame has been determined to be an erasure frame is received from a plurality of receiver wireless communications devices. The indications of if the received frame has been determined to be an erasure frame are aggregated. The frame identified by the frame identifier is declared to be an erasure frame when at least one of the plurality of wireless communications devices has indicated the received frame has been determined to be an erasure frame. That an error occurred on an uplink between the sender wireless communication device and the RAN is determined when the frame is declared an erasure frame.

Disclosed are methods for avoiding, detecting, and mitigating message faults. Due to the expected large increase in electromagnetic background energy in in dense 5G and 6G networks, message faults are likely to dramatically increase, along with their costs. To avoid intermittent interference, a user device can monitor the noise level and request that the base station store incoming messages while the noise level is too high. Likewise, if a user device receives a faulted message while the noise level is high, the user device can delay the retransmission until the noise subsides. If the user device has received two faulted messages (a likely scenario in crowded urban/industrial/sporting environments), the user device can merge the two versions while selecting the message elements with the best quality (based on modulation, SNR, stability, and other criteria) and may thereby obtain a corrected message version, without resorting to a third transmission of the message.

In an embodiment, a method of determining whether to trigger an event based on data blocks having status data includes electronically receiving the data blocks over a channel, performing a data integrity check on the data blocks to determine whether a particular data block has a transmission fault, calculating a received error metric based on performing the data integrity check, and disabling an event trigger if the received error metric crosses a first error threshold.

An optical frame is received over an optical link within an optical network. The optical frame contains a payload of aggregated data, an alignment value, and a bit interleaved parity value. The content of the optical frame is aligned based on the alignment value. The bit interleaved parity value is monitored. In response to the monitoring, a transmission quality of the transmission link is determined.

In accordance with an embodiment the method includes temporarily configuring the vector processor with a new set of vectoring coefficients during one or more selected symbol positions; restoring the current set of vectoring coefficients outside the one or more selected symbol positions; obtaining at least one error measure over respectively at least one line of the group of vectored lines during the one or more selected symbol positions; and determining a suitability indication for the new set of vectoring coefficients based on the obtained at least one error measure.

Faulted messages in 5G or 6G are generally discarded and a retransmission is then requested. However, the faulted message contains valuable information despite the few faulted message elements. Retransmission is a time-consuming energy-intensive process. Therefore, the present disclosure pertains to procedures for determining which specific message elements, of a corrupted message, are actually faulted. To do so, the receiver can determine a modulation quality of each message element by measuring a difference between the amplitude levels of the message element and the predetermined amplitude levels of the modulation scheme. For example, the modulation scheme may involve an I-branch and an orthogonal Q-branch, each with a different amplitude. The message quality may be related to the deviation of each branch amplitude from the closest predetermined amplitude level of the modulation scheme. A large amplitude deviation indicates a suspicious message element. Many other aspects are also disclosed.
