Abstract: When two different messages are transmitted at the same time in 5G or 6G, the message is “collided”. The resulting interference causes a message fault, necessitating a costly retransmission. Disclosed is a modulation scheme in which the modulation states are configured so that a message element can be collided by an intruder message, yet the receiver can still recover the original message element. In other cases, depending on the colliding states, the receiver can narrow the possible values of each faulted message element to just two or three possibilities, thereby greatly reducing the amount of time required for testing each combination against an error-detection code. Especially under high-noise conditions, the collision-proof modulation scheme may enable enhanced throughput by identifying and mitigating the faulted message element, and may thereby avoid unnecessary retransmissions.

Abstract: Feedback messages are essential for controlling transmission beams between network devices in 5G and 6G. Disclosed are brief signals and procedures for a user device to provide feedback to a base station on beam direction, transmission power, beam width, and other transmission parameters. The resource cost is so low, the base station can provide alignment test signals with each downlink message, and the user device can provide feedback selecting a best-received test signal as part of each uplink message, such as an acknowledgement. With such near-real-time beam fine-tuning, base stations and user devices can maintain the tight directional communications required for next-generation communications, without burdening the network with cumbersome feedback messages of prior art. Numerous other aspects are disclosed.

Abstract: In 5G-Advanced and 6G, due to the higher frequencies involved, phase noise is expected to be a major source of faults. Disclosed herein is a small (single resource element) phase-tracking reference signal that also provides an updated amplitude calibration. The compact phase-tracking reference signal, in QAM, includes a first branch at a maximum amplitude and an orthogonal second branch at either the maximum amplitude or zero amplitude, as transmitted. The receiver can readily determine a phase rotation angle according to a ratio of the two branch amplitudes, and also an amplitude calibration according to the vector magnitude of the received branches, thereby negating both amplitude noise and phase noise.

Abstract: Beamforming is a critical element of 5G and especially 6G, but currently requires a series of time-consuming and resource-consuming messages. Disclosed are procedures by which base stations can transmit a phased beam pulse, having a phase that varies with angle, so that each user device can measure the received phase of the pulse and thereby determine its angle relative to the base station. Each user can then sequentially inform the base station of its orientation relative to the base station, or can append that information to another message such as an initial access message or an acknowledgement, for example. The user device and the base station can then exchange messages in narrow beams aimed at each other according to the alignment angle. Also disclosed are procedures to economically generate the wide-angle phased beam by combining overlapping beams of various phases.

Abstract: Reliability, in 5G and emerging 6G, is a continuing challenge due to signal fading, heavy interference, and phase noise, among others. The disclosed procedures show how to locate the most likely faulted message elements according to a deviant modulation, excessive amplitude or phase instability, and inconsistency between successive transmissions of the message. In addition, the receiver can rectify the message either by altering the faulted message elements to other modulation states, or by selectively merging two versions of the message according to signal quality. In either case, reliability is improved, range is extended, and time is saved.

Abstract: An autonomous or semi-autonomous vehicle can detect an imminent collision according to sensor data and responsively select an action or a sequence of actions to avoid the collision if avoidable, and to reduce or minimize the harm of the collision if unavoidable. An artificial intelligence model may be used to process the sensor data, detect the imminent collision, and select the collision avoidance action or actions, or the harm-reduction or harm-minimization action or actions. For example, when the collision is considered unavoidable, the vehicle may apply the brakes to reduce the vehicle's speed and therefore, the severity of the impact. When the collision is considered avoidable, the vehicle may automatically apply steering to avoid the potential collision, such as when the vehicle is departing a lane and may collide with a vehicle traveling in the same or opposite direction.

Abstract: A 5G/6G network can include a modulation scheme for uplink and downlink messaging using a special zero-power modulation level, in addition to the regular amplitude modulation levels of, for example, QAM. The receiver can demodulate each message element by comparing the amplitude to the various amplitude levels, including the zero-power level, and thereby increase the bits per message element, and hence the communication throughput, at no increase in transmitted power. In addition, the zero-power states can reveal intrusive noise and interference in the proximate message, enabling correction before the demodulation. The zero-power amplitude may be added to conventional modulation schemes, such as an additional zero-power amplitude level in QAM, PSK, and amplitude-phase modulation schemes, thereby providing greater versatility at little or no cost and no additional transmission power.

Abstract: For more efficient use of the limited bandwidth in 5G and 6G communications, and to enable longer battery life in remote user devices, the user device can request that unnecessary downlink control messages be withheld. Instead, a custom search-space can be assigned to the user device, such that all downlink data messages will begin in one of the resource elements of the custom search-space, thereby greatly simplifying the user device's task of detecting its incoming messages in a stream of unrelated transmissions. In addition, the user device can request that the user device's identification code, and optionally the length of the data message, be prepended to the data message, for further assistance to low-cost reduced-capability user devices that do not require low latency.

Abstract: Disclosed are systems and methods for autonomous vehicles and vehicles with automatic driver-assistance systems (ADAS) to automatically detect an imminent collision, determine whether the collision is avoidable or unavoidable, and plot a course minimizing the hazard using an artificial intelligence (AI) model. For example, a collision is avoidable if the vehicle can avoid it by steering, braking, and/or accelerating in a particular sequence. The AI model finds the best sequence for collision avoidance, and if that is not possible, it finds the best sequence for minimizing the harm. The harm is based on an estimated number of fatalities, injuries, and property damage predicted to be caused in the collision. The AI-based situation analysis and sequence selection are directly applicable to human-driven vehicles with an emergency-intervention ADAS system, as well as fully autonomous vehicles. With fast electronic reflexes and multi-sensor situation awareness, the AI model can save lives on the highway.

Abstract: A network architecture is disclosed for intrinsic cybersecurity of low-cost, low-complexity IoT devices such as single-task sensors and actuators. The IoT devices are configured in a star topology sub-network, in which a number of IoT “end devices” communicate exclusively with a single “hub device” that manages the sub-network. The hub device is also connected to a larger network such as a 5G or 6G network. Each end device makes a measurement or operates an actuator on instructions from the hub device, and transmits data results back to the hub device, which then transmits the results (or a summary thereof) up to the base station of the larger network. Thus the larger network is relieved of responsibility for routine managing of the end devices, since the hub device does that. Also the larger network is protected from cyberattacks by configuring each end device to boot and execute from ROM, and other features described herein.
