  • 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.
