Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.

Disclosed are procedures for measuring the modulation quality of each message resource element in a failed 5G or 6G communication modulated according to pulse-amplitude modulation, thereby revealing the most likely fault locations in the message. A second copy of the message can be merged by selecting the highest quality message elements from each version, where the quality is related to how far each message element's modulation deviates from the calibrated “states” of the modulation scheme. The receiver may also determine directional information based on the modulation of each message element, and may compare versions to determine the most likely correct state of each message element. Such strategies may directly recover the original message, or may greatly reduce the number of variations that need to be tested. When implemented, fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.

Artificial intelligence procedures are disclosed for localizing faults in corrupted messages in 5G and 6G, and for correcting those faults based on measured parameters such as backgrounds and message signals according to pulse-amplitude modulation. An AI model with multiple adjustable variables may be “trained” using a large number of message events, including faulted messages, to determine which message elements are likely faulted, based on input parameters such as modulation quality, SNR, and other signal properties. The receiving entity can then attempt a grid search to correct the faulted message elements, or request a retransmission. For field use by base stations and user devices, an algorithm may be developed based on the AI model, and configured to predict which message elements are likely faulted. By detecting and correcting message faults, networks may increase reliability and reduce latency while avoiding most retransmission costs and delays, according to some embodiments.

When a received message is found to be corrupted in 5G or 6G, the receiver can request a retransmission. If only one message element is faulted, retransmitting the whole message may be a waste. Procedures are disclosed for the receiver to determine which message elements are likely faulted by measuring the modulation quality and optionally other signal quality factors. The receiver can then indicate, in an acknowledgement for example, which portion of the message needs to be retransmitted. After receiving that retransmitted portion, the receiver can then produce a merged version by substituting the retransmitted portion into the as-received message. Alternatively, the receiver can select the best-quality elements from the two versions for the merged copy, and thereby eliminate most or all of the faults. Networks supporting these protocols may have fewer delays, faster responses, improved reliability, and reduced resource usage by avoiding unnecessary retransmission volumes.

Message failures due to noise and interference cause unnecessary delays and reduction in reliability in wireless networks. To detect, localize, and correct transmission faults in 5G and 6G networks, the receiver can measure the “modulation quality” of each message resource element modulated in PAM (pulse-amplitude modulation), according to how closely the amplitudes of the in-phase and quad-phase signal branches match the amplitude levels of the modulation scheme. If the message is faulted, the receiver can re-assign each message element with poor modulation quality to the adjacent states, or if necessary to each state in the modulation scheme, and may thereby find the correct message value in many cases. When implemented, message fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.

An apparatus configured to be employed in a victim transmission reception point (TRP) associated with a new radio (NR) communication system is disclosed. The apparatus comprises a memory interface and a processing circuit. In some embodiments, the processing circuit is configured to process one or more predefined interference signals respectively received from one or more interfering TRPs during a guard period of the victim TRP. In some embodiments, the guard period comprises a time period between a downlink (DL) transmission and an uplink (UL) transmission associated with a time division duplex (TDD) frame of the victim TRP. In some embodiments, the processing circuit is further configured to determine an inter-TRP interference based on the one or more predefined interference signals. In some embodiments, the inter-TRP interference comprises a measurement of a UL interference at the victim TRP from the one or more interfering TRPs.

In one example, a communications circuit processes an amplitude modulated signal by using a first circuit having signal paths to process an amplitude modulated signal as represented by an in-phase component and by a quadrature component, and by using a second circuit to discern random noise pulses from the quadrature component of the amplitude modulated signal. In response, the second circuit generates an estimate of overall noise representing the random noise pulses in the amplitude modulated signal. In the above and more specific examples, the random noise pulses may appear as pulses which overlap with, in terms of time and bandwidth of frequency spectrum, information of the amplitude modulated signal, and the first and second circuits may be part of an RF radio receiving the amplitude modulated signal from an antenna.

A user equipment (UE) and a base station utilize dynamic numerology for adaptation of a link between the UE and the base station. The UE may determine a recommended subcarrier spacing to use for a downlink transmission based on the modulation and coding scheme to be used for the downlink transmission and transmit the recommended subcarrier spacing to the base station. The UE may also transmit a report containing channel state information to the base station and the base station may determine the subcarrier spacing to use for the downlink transmission based on the report.
