摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Cybersecurity is a critical requirement for 5G-Advanced and 6G, in part due to the large attack surface represented by the exponentially increasing number of reduced-capability devices needing wireless service but intensely cost-constrained by their applications. Therefore, disclosed is a network topology that enables an unlimited number of basic sensor/actuator “end devices” to communicate, securely, with a user device of a managed 3GPP-compliant network. The user device or “hub” device serves as both manager and gateway, and more importantly, as a firewall preventing attackers from penetrating the managed network through the end devices. In addition, the end devices can obtain iron-clad protection by booting and operating from ROM only, and transferring only pre-configured replies up to their hub device. The topology enables the hub and end devices to perform the edge work largely autonomously, while insulating the managed network from cyberattacks.

摘要： A faulted 5G/6G message may be recovered by finding the faulted message elements and altering them until the fault is corrected. Disclosed are methods to evaluate the modulation quality of each message element using multiple criteria. The receiver can determine a first quality by measuring the overall (sum-signal) amplitude and phase of each message element, and comparing to the predetermined amplitude and phase levels. The receiver can determine a second quality by separating the overall wave into orthogonal components (branches) and comparing the branch amplitudes to the predetermined levels. The receiver can determine a third quality according to the SNR of the overall signal and the two branch signals. By combining the first, second, and third quality factors, the receiver can identify the most likely faulted message elements. The receiver can then alter the worst message elements in a nested grid search to find the correct message version.

摘要： Message faults are expected to become a major problem for next-generation 5G/6G networks, due to signal fading, high backgrounds, and high density of users. Disclosed are methods to modulate and demodulate messages to optimize noise margins, greatly enhancing reliability at negligible cost, according to some embodiments. A transmitter can modulate a message using amplitude-phase modulation, yet a receiver can conveniently receive and process the signals according to separate in-phase (I) and quad-phase (Q) branches, that is, according to QAM. The receiver can then convert the I and Q values to the original waveform amplitude and phase mathematically, and then demodulate those values using predetermined amplitude and phase levels as provided by a proximate demodulation reference. By converting the as-received QAM values to the as-transmitted amplitude-phase values, the receiver can thereby avoid many noise vulnerabilities inherent in QAM-modulated messages, and thereby obtain the full noise margins provided by amplitude-phase modulation.

摘要： A first vehicle in traffic can use machine learning and artificial intelligence to detect an imminent collision with a second vehicle or other object. A well-trained AI algorithm can select a sequence of actions (braking, swerving, or accelerating—depending on the specific kinetics) to avoid the collision if possible, and to reduce or minimize the harm if unavoidable. With proper training, the AI model may also infer the intent and future actions of the second vehicle, as well as potential interference of other traffic agents. A good algorithm can also infer the intent of the driver of the first vehicle, for example based on prior driving habits. The AI algorithm may be implemented in a processor on the subject vehicle, potentially in communication with another processor at a fixed site such as a local access point or a central supercomputer. With super-fast AI solutions, lives will be saved!
