Abstract: Methods and apparatuses are provided in which sidelink control information (SCI) including information on a resource occupied by a receiving terminal, is received at a transmitting terminal, from the receiving terminal. A retransmission scheme of the transmitting terminal is identified. Based on the identified transmission scheme, a threshold is determined for transmission resource selection for a resource identified based on the information on the resource. The transmission resource selection is performed according to a sidelink measurement for the identified resource. The sidelink measurement is performed based on the determined threshold.
