  • Patent number: 11510243
    Abstract: This disclosure provides systems, methods, and apparatuses for a beam-based channel access countdown procedure. In one aspect, a channel sensing beam may be permitted to include one or more transmit beams and, thus, may differ from a transmit beam that is to be used for a transmission. As such, defining a manner in which a channel access countdown procedure is performed is desirable. Some aspects described herein provide techniques and apparatus for a beam-based channel access countdown procedure. In some aspects, the systems, methods, and apparatuses described herein provide a beam-based channel access countdown procedure that allows a single channel sensing beam, including multiple transmit beams, to be utilized in association with determining channel availability for the multiple transmit beams, thereby improving performance of beam-based directional transmissions.

  • Patent number: 11088780
    Abstract: Blind detection of code rates for codes with incremental shortening involves determining a decoding code rate for decoding words that are based on codewords of a code that exhibits incremental shortening over a range of code rates. Incremental shortening is a code structure or coding property according to which different numbers of bits in encoding blocks that are to be encoded are set or frozen to a fixed value, to provide the range of code rates. This property enables blind detection of a decoding code rate, without explicit signaling or prior configuration of code rates between a transmitter and a receiver.

  • Patent number: 11089376
    Abstract: Apparatus for rating download events is described. The apparatus includes a network interface and a processor. The processor, via the interface, monitors one or more download events in which content is downloaded by one or more users. In response to the monitoring, the processor identifies at least one quantitative property of the download events. Based on the property, the processor assigns a rating to the download events that is indicative of an estimated user-perceived quality of the download events. The processor then generates an output indicative of the rating. Other embodiments are also described.
