    Abstract: A wireless system comprises a controlling node and multiple antenna processing nodes coupled to the controlling node but separated from each other. The controlling node receives (720) first soft bit information from a first antenna processing node, the first soft bit information corresponding to reception of a wireless transmission. Responsive to determining that it cannot decode transmitted bits using the first soft bit information, the controlling node requests (730) and receives (740) second soft bit information from a second antenna processing node, the second soft bit information also corresponding to the first wireless transmission from the wireless device and having been buffered by the second antenna processing node. The controlling node decodes (750) bits from the first wireless transmission using both the first and second soft bit information. The controlling node may then signal the antenna processing nodes that they can discard buffered information for the wireless transmission.

    Abstract: The present invention is directed to data communication systems and methods thereof. According to various embodiments, the present invention provides a communication with a reconfigurable forward-error-correction (FEC) module. The FEC module processes data received from two or more communication lanes, and depending on the mode of operation, the FEC module can combine data from the two or more communication lanes and perform error correction on the combined data, or the FEC module can processes data from the two communications lanes separately and perform error correction independently for the each of the data communication lanes. There are other embodiments as well.

    Abstract: This disclosure introduces an advancement to the error indication message to provide detailed information about errors in configurations that are arriving from the Layer 2 to the Layer 1. A method is disclosed, comprising: performing physical layer control (PHY) of a wireless signal at a Layer 1 (L1) software module; performing medium access control (MAC) of the wireless signal at a Layer 2 (L2) software module; providing an application programming interface between the L1 software module and the L2 software module for receiving L1 configuration messages and providing error codes to the L2 software module; receiving a L1 configuration message at a Layer 1 software module; and providing an enhanced error code progressively from a L1 software module to the Layer 2 (L2) software module.

    Abstract: Computer-implemented systems and methods for Forward Error Correction (FEC) at the IP-Layer with adaptive bandwidth overhead minimization in a packet transmission network, the system including an FEC encoder to process IP packets and generate FEC encoded packets and repair packets, an FEC decoder to receive and process the FEC encoded packets and repair packets, and an FEC controller that includes a set of computer-implemented instructions to carry out functions including configuring an FEC algorithm to control FEC encoding and decoding, packet recovery, and retrieve packet transmission statistics, determining if network bandwidth overhead needs adjustment, controlling tuning parameters, and implementing predictive analysis based at least in part on historic data.

    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.
