Claim 0:
1. A method for switching resource pools by a device in a wireless communication system, the method comprising:
receiving, from a base station, system information block (SIB) including first vehicle-to-everything (V2X) configuration information associated with normal resource pools and second V2X configuration information associated with exceptional resource pools, wherein the first V2X configuration information and the second V2X configuration information indicate resources for a sidelink communication;
sensing the normal resource pools indicated by the first V2X configuration information included in the SIB;
determining whether a result of the sensing the normal resource pools is available;
selecting one of the normal resource pools indicated by the first V2X configuration information in case that the result of the sensing the normal resource pools is available;
selecting, by using random selection, one of the exceptional resource pools indicated by the second V2X configuration information included in the SIB in case that the device is in idle mode and the result of the sensing the normal resource pools is not available; and
transmitting sidelink control information and data based on a resource of the selected resource pool,
wherein the first V2X configuration information is different from the second V2X configuration information.
