Abstract: Artificial Intelligence (AI) can rapidly evaluate a faulted message in 5G or 6G, calculate a likelihood that each message element is faulted, and optionally suggest a most probable corrected version for each of the likely faulted message elements. To do so, the AI takes in numerous factors besides the message itself, such as the modulation quality of each message element, the proximity and quality of a nearest demodulation reference, a signal-to-noise ratio of the message element, a measure of current electromagnetic noise during the message element, an expected format or expected codewords based on prior messages or convention, and other factors. The AI model can then provide guidance as to mitigation, such as choosing whether to request a retransmission or attempting to vary the likely faulted message elements. The AI model can be adapted to fixed-site computers or to the more limited computers of a mobile user device.

Abstract: Example communication methods and apparatus are described. One example method includes sending a first training signal by a first device to a second device on a reflection path. The first device sends a second training signal to the second device on the reflection path. The reflection path is a transmission path formed after the first training signal and the second training signal are reflected by a surrounding object. An interval between the first training signal and the second training signal is used to indicate to decode data.

Abstract: A method performed by a node in a wireless communication network of estimating parameters used for determining a signal-to-interference measure at a communication device served by a base station, and a node performing the method. The method comprises acquiring an estimate of channel condition between the communication device and the serving base station, and between the communication device and at least one base station of a neighbouring cell, estimating the signal-to-interference measure using the estimate of the respective channel condition, and acquired output power and Physical Resource Block (PRB) utilization of each of the base stations, and receiving an indication of quality of a channel via which the communication device is served by the base station. The method further comprises determining whether a change in the estimate of the signal-to-interference measure is required based on the indication of channel quality, and updating the estimate of the channel condition.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication by a wireless device with a first AP are provided. In one aspect, an apparatus is configured to receive a valid Overlapping Basic Service Set (OBSS) PPDU transmission, e.g., transmitted by a second wireless device to a second AP. The apparatus may regard the valid OBSS PPDU as not having been received when a received power of the OBSS PPDU is below an OBSS Packet Detection (PD) level, and determine a transmission power (TXPWR) for a reuse transmission from the wireless device to the first AP based on an OBSS Packet Detection (PD) threshold and based on a TXPWR definition.
