Abstract: A method of operating the first apparatus 100 in a wireless communication system is proposed. The method may include: performing resource selection for at least one period, wherein each of the at least one period includes at least one transmission resource; increasing a value related to a consecutive unused transmission opportunity by 1, based on that transmission is not performed on all transmission resources within a first period included in the at least one period; and triggering resource reselection based on that the value related to a consecutive unused transmission opportunity reaches a threshold value related to a consecutive unused transmission opportunity.
