Abstract: 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.

Abstract: The present invention provides methods, apparatus and systems for improving a systems-level data rate on a communications link such as the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.

Abstract: Systems and methods for selecting a communication mode in a wireless network (10) include a communication mode selection procedure that may be carried out by the respective devices in an automated manner to identify a mode for communication between an electronic device (14) and a network node (12). The selection may be between P-MIMO Mode A, P-MIMO Mode B, B-MIMO Mode A, or B-MIMO Mode B. Determining the desired mode for communication is based on the ability and/or desirability of the network node (12) to efficiently process a maximum threshold number of electronic devices using the P-Mimo Mode A or B-MIMO Mode A and, thereafter, granting MIMO Mode B communication access to any subsequent electronic devices joining the communication network. Communication mode selection may occur dynamically based on changing channel conditions caused by mobility of the electronic user equipment devices and what overlapping and/or non-overlapping beams are needed to be used.
