Abstract: In a method for resource determination for sidelink communications, a first terminal apparatus determines an available time-frequency resource set in a resource selection window based on resource reservation information of a second terminal apparatus and a first channel occupancy time. The first channel occupancy time is shared by the first terminal apparatus and the second terminal apparatus. When a time-frequency resource occupied by another terminal apparatus during resource selection is excluded, the first terminal apparatus does not need to exclude a time-frequency resource unit reserved by that other terminal apparatus except when it is the second terminal apparatus, to prevent excessive time-frequency resource units from being excluded.
