  • Patent number: 11483101
    Abstract: Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a pseudorandom number sequence, or “PN sequence”) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

  • Patent number: 11483798
    Abstract: A notification server is provided for a multi-network wireless communication system. The notification server includes a processor and a memory having computer executable instructions stored therein. The instructions, when executed by the processor, cause the processor to receive first device information from a mobile communication device wirelessly connected to a macro cell network of the multi-network wireless communication system. The instructions further cause the processor to determine, based on the received first device information, that a small cell network of the multi-network wireless communication system is available for communication with the mobile communication device. The instructions further cause the processor to transmit a notification to the mobile communication device to search for the small cell network for transition thereto.

  • Patent number: 11476975
    Abstract: A receiver is configured to capture a plurality of linearly distorted OFDM symbols transmitted over a signal path. The receiver forms the captured OFDM symbols into an overlapped compound data block that includes payload data and at least one pseudo-extension, processes the overlapped compound block with circular convolution in the time domain using an inverse channel response, or frequency domain equalization, to produce an equalized compound block, and discards end portions of the equalized block to produce a narrow equalized block. The end portion corresponds with the pseudo-extension, and the narrow block corresponds with the payload data. The receiver cascades multiple narrow equalized blocks to form a de-ghosted signal stream of OFDM symbols. The OFDM symbols may be OFDM or OFDMA, and may or may not include a cyclic prefix, which will have a different length from the pseudo-extension.

  • Patent number: 11468273
    Abstract: The present disclosure generally relates to apparatus, software and methods for detecting and classifying anomalous features in one-dimensional data. The apparatus, software and methods disclosed herein use a YOLO-type algorithm on one-dimensional data. For example, the data can be any one-dimensional data or time series, such as but not limited to be power over time data, signal to noise ratio (SNR) over time data, modulation error ratio (MER) data, full band capture data, radio frequency data, temperature data, stock data, or production data. Each type of data may be susceptible to repeating phenomena that produce recognizable anomalous features. In some embodiments, the features can be characterized or labeled as known phenomena and used to train a machine learning model via supervised learning to recognize those features in a new data series.
