Abstract: Additional information can be packed into each message element of a 5G/6G message by varying the amplitude of the signal within the symbol-time of the message element. For example, the difference between the amplitude at the beginning and ending of the symbol-time may encode additional bits, thereby providing higher information density in each transmission. The amplitude variation may be abrupt, such as a sudden change from the first amplitude value to the second amplitude value in the middle of the symbol-time, or it may be a gradual linear ramp spanning the symbol-time. In either case, the modulation scheme may include amplitude variation levels as well as the amplitude levels themselves, thereby providing a larger modulation space and hence shorter messages. Effects on crosstalk and frequency offset due to the amplitude variation, and their mitigation, are also disclosed.

Abstract: A compact demodulation reference is disclosed for compatibility with reduced-capability user devices, and for enhanced throughput for high-performance user devices of 5G and 6G in high-density environments. The demodulation reference, in some embodiments, occupies only one resource element, yet provides sufficient information to enable a receiver to calculate all of the amplitude or phase modulation levels of the modulation scheme. For example, if the modulation scheme is 16QAM, the demodulation reference can include an I branch with the highest amplitude level of the modulation scheme and an orthogonal Q branch with the lowest amplitude level. Further examples apply to a multiplexed amplitude-phase modulation scheme. In each case, the receiver can calculate the remaining amplitude (or phase) modulation levels, and thereby demodulate a proximate message. Further examples show how to reveal faulted message elements by comparing demodulation with QAM and amplitude-phase demodulation, and how to optimize noise margins.

Abstract: Phase noise is an unsolved, limiting factor for high frequency communications envisioned for 6G. Proposed herein are phase-tracking reference signals embedded in each guard-space of a message. The receiver can recalibrate the phase noise, and amplitude noise as well, with based on each guard-space reference signal, thereby providing extremely localized noise compensation including amplitude and phase distortions and including rapidly-varying frequency-dependent distortions characteristic of interference, on a symbol-by-symbol basis, at zero cost in message throughput and transmission power. The normal functions of a cyclic prefix in the guard-space can be provided by tailoring the guard-space reference signal, as detailed herein. Examples show how guard-space reference signals provide a fault-mitigating capability that is enabling to 6G mmWave objectives.

Abstract: 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.

Abstract: Message faulting is expected to be a major challenge in 5G-Advanced and especially 6G, due to increased pathloss and phase noise at FR2 frequencies, and exponential crowding of networks. Legacy methods for forward-correction or automatic retransmissions are unsuitable to the fast-paced demands of next-generation users. Therefore, disclosed herein is an AI-based receiver that interprets a corrupted message to determine the most likely meaning or intent, and thereby provides one or more candidate corrected messages along with a likelihood that each of the candidate corrected messages is indeed correct. The AI model may also be provided with data on the context or current activity of the receiver, data on the waveform of each message element, and other data available to the receiver, so that the AI model can further refine the likelihood values. By recovering corrupted messages in the receiver, a costly retransmission may be avoided, saving time and resource usage.

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.

Abstract: Communications between user devices and base stations in 5G/6G, and in earlier generations, often permit gross unfairness in allocating transmission opportunities. A user device that has previously been denied permission to transmit is more likely to be denied again, whereas in a fair system the longest-delayed user device would be granted uplink permission soonest (QOS and priorities being equal). Therefore, herein is disclosed a base station protocol in which each user device's delay history is recorded and, when that user device again requests permission to transmit, that user device is granted sooner than the other users who have not been delayed, or not as long as the most-delayed user device. In versions, the user devices may report their accumulated delay times, or the base station may count the number of delay events each user device has experienced.

Abstract: In 5G and 6G, users at high traffic density can be forced to delay transmissions to avoid collisions, and by convention the delay interval is increased upon each instance. This convention penalizes those who have been delayed the most, resulting in excessive latency, gross unfairness, and the blocked-node problem whereby certain users are denied access indefinitely. Disclosed are improved protocols whereby users can delay by shorter intervals upon each successive backoff, thereby reducing overall delays, greatly reducing message failure rates, and providing enhanced fairness overall. The protocols detailed herein can enable wireless users to communicate with fewer and shorter interference delays, while the base station can clear the waiting list sooner, and network operations can be improved generally. Numerous additional aspects are disclosed.

Abstract: Networks operating at high frequencies in 5G and 6G may reduce the incidence of phase faulting by declaring that, above a specified frequency, messages are to be modulated according to multiplexed amplitude-phase modulation, instead of the QAM modulation generally used at lower frequencies. Multiplexed amplitude-phase modulation can provide larger phase margins than QAM of the same order, by arranging the modulation phase levels to be equally spaced-apart which they are not in QAM. For example, with 4 amplitude and 4 phase levels (16 states), the various modulation states can be separated by 90 degrees of phase, whereas in 16QAM the minimum phase separation is only 36.9 degrees, a serious problem at higher frequencies where phase noise predominates. In addition, QAM cannot accommodate non-square modulation tables, which are readily provided by amplitude-phase modulation, further enhancing fault-mitigation options.

Abstract: An unsolved problem in 5G and 6G is how a mobile user device can select the most appropriate base station or access point for communication. Currently, the user device is forced to do a tedious and time-consuming blind search, and even then is not guaranteed to have found the best one. Therefore, to assist user devices (especially reduced-capability IoT devices) in network discovery, disclosed herein is a “hailing” message that the user device can broadcast, and determine from the base station reply messages which one is closest, or has the best signal, or other criterion. The base stations, upon detecting the hailing message, can use an AI model to determine whether they can accommodate another user device (optionally with coordination among multiple access points for load-leveling), and if so, can transmit a reply message after a delay related to the received power in the hailing message.
