Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of Channel Occupancy Time (COT) for Sidelink (SL) communication in Unlicensed band (U-band). The method includes receiving, at a first device and from a second device, configuration information associated with a COT at least for a SL transmission of the first device on an unlicensed resource pool allocated for the first device, the configuration information at least indicating whether a listen before talk procedure is required to be performed at the first device within the COT before the SL transmission; and performing the SL transmission within the COT based on the configuration information. In this way, the COT sharing mechanism can be used for SL communications in U-band and therefore a sensing procedure for resource selection may not be impacted by the LBT procedure.
