Method and apparatus for transmitting and receiving sidelink signal in wireless cellular communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• identifying a transmission of a first sidelink signal associated with a first radio access technology (RAT) and a transmission of a second sidelink signal associated with a second RAT;
• identifying whether the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal on a time domain;
• and
• transmitting one sidelink signal among the first sidelink signal or the second sidelink signal based on a first priority associated with the first sidelink signal and a second priority associated with the second sidelink signal, in case that the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• identify a transmission of a first sidelink signal associated with a first radio access technology (RAT) and a transmission of a second sidelink signal associated with a second RAT,
• identify whether the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal on a time domain, and
• transmit, via the transceiver, one sidelink signal among the first sidelink signal or the second sidelink signal based on a first priority associated with the first sidelink signal and a second priority associated with the second sidelink signal, in case that the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal.
