Method and apparatus for transmitting and receiving information related to resource collision in NR V2X

A first device adapted to perform wireless communication, the first device 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 by the at least one processor, perform operations comprising:
• receiving, through a first physical sidelink control channel (PSCCH), first sidelink control information (SCI) including a first priority value and information related to a first resource reserved by a second device;
• receiving, through a second PSCCH, second SCI including a second priority value and information related to a second resource reserved by a third device;
• determining that the first resource and the second resource overlap;
• determining a physical sidelink feedback channel (PSFCH) resource for PSFCH transmission with conflict information corresponding to the first resource;
• and
• performing the PSFCH transmission with the conflict information to the second device.

A processing device adapted to control a first device, the processing device comprising:

• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, through a first physical sidelink control channel (PSCCH), first sidelink control information (SCI) including a first priority value and information related to a first resource reserved by a second device;
• receiving, through a second PSCCH, second SCI including a second priority value and information related to a second resource reserved by a third device;
• determining that the first resource and the second resource overlap;
• determining a physical sidelink feedback channel (PSFCH) resource for PSFCH transmission with conflict information corresponding to the first resource;
• and
• performing the PSFCH transmission with the conflict information to the second device.
