Method and device for performing communication on basis of interference information in nr V2X

A first user equipment (UE), comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the first UE to perform operations comprising:
• obtaining information related to a resource pool for inter-UE communication;
• triggering a resource selection procedure;
• based on the resource selection procedure being triggered, determining a plurality of candidate resources in the resource pool within a selection window;
• selecting at least one transmission resource among the plurality of candidate resources;
• and
• performing reselection for a carrier or a bandwidth part (BWP), based on that a number of failed transmissions performed on the at least one transmission resource, due to in-device coexistence (IDC) interference, is greater than or equal to a threshold.
