1. A method performed by a first device in a wireless communication system, the method comprising:
receiving, from a second device, first information related to a first resource reserved by the second device, the first information including information related to a first transmission priority;
receiving, from a third device, second information related to a second resource reserved by the third device, the second information including information related to a second transmission priority;
determining the first resource and the second resource overlap in time and frequency; and
transmitting conflict information through a physical sidelink channel,
wherein based on the determination that the first resource and the second resource overlap in the time and the frequency, and based on that the second transmission priority is higher than the first transmission priority, the conflict information is transmitted to the second device,
wherein, based on the determination that the first resource and the second resource overlap in the time and the frequency, and based on that the first transmission priority is higher than the second transmission priority, the conflict information is transmitted to the third device, and
wherein, based on the determination that the first resource and the second resource overlap in the time and the frequency, and based on that the first transmission priority is equal to the second transmission priority, the conflict information is transmitted to either the second device or the third device.
