  • Patent number: 11622385
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting a minimum measurement duration in listen-before-talk (LBT) sensing slots for high band unlicensed channel access. In some examples, a device may select a minimum sensing duration for an LBT procedure according to a sensing bandwidth or an energy threshold (such as an energy detection threshold or an energy power spectral density threshold), or both. As part of the LBT procedure, the device may measure or sense a wireless channel for at least the selected minimum sensing duration in each sensing slot of the LBT procedure. The device may selectively transmit on the wireless channel according to a result of the LBT procedure. For example, the device may either transmit or refrain from transmitting on the wireless channel depending on whether the device senses the wireless channel to be available.

  • Patent number: 11620344
    Abstract: A new transaction set is compared to a plurality of transaction sets represented in a Compressed Frequent Item Set (CFIS), wherein the CFIS maintains a count for each transaction set represented in the CFIS. When the new transaction set matches a transaction set represented in the CFIS, the count for the matching transaction set in the CFIS is incremented. When the new transaction set does not match any transaction sets represented in the CFIS, the new transaction set is added to the CFIS. If there are intersections between two or more events of the new transaction set and the events of the plurality of transaction sets represented in the CFIS, the count for the transaction sets in the CFIS that intersect with two or more of the events of the new transaction set is incremented.
