  • Publication number: 20230300885
    Abstract: A method can include determining candidate sidelink resources by a user equipment (UE) for sidelink transmission on an unlicensed band from a sidelink resource selection window based on results of a sensing operation on the unlicensed band during a sidelink sensing window, selecting a sidelink resource from the candidate sidelink resources, performing a listen-before-talk (LBT) process on the unlicensed band to obtain a channel occupancy time (COT), and performing a sidelink transmission within the COT using the first sidelink resource. The selection of the sidelink resource can be based on an LBT time that is a predicted duration of a random backoff process of the first LBT process. Also, the first sidelink resource can be selected from the candidate sidelink resources without randomization.

  • Patent number: 11765349
    Abstract: Method and apparatus of coding pictures containing one or more virtual boundaries, such as 360-degree virtual reality (VR360) video are disclosed. According to this method, a reconstructed filtered unit associated with a loop filter for a current reconstructed pixel is received. The loop filtering process associated with the loop filter is applied to the current reconstructed pixel to generate a filtered reconstructed pixel, where if the loop filtering process for the current reconstructed pixel is across a virtual boundary of the picture, the loop filtering process is disabled when fixed-size loop filtering is used or a smaller-size loop filter is selected when adaptive-size loop filtering is used for the current reconstructed pixel, where the filtered reconstructed pixel is the same as the current reconstructed pixel when the loop filtering process is disabled. The filtered reconstructed pixel is the same as the current reconstructed pixel.
