Method and apparatus for configuring transmission priority for direct communication in wireless communication system

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

• generating configuration information on at least one sidelink resource pool, wherein the configuration information includes information on whether a physical sidelink feedback channel (PSFCH) is configured for each of the at least one sidelink resource pool;
• and
• transmitting the generated configuration information,
• wherein in case that a sidelink hybrid automatic repeat request (HARQ) feedback is enabled in a terminal which receives the configuration information, any sidelink resource pool configured with the PSFCH is used for sidelink data transmission on a physical sidelink shared channel (PSSCH), among the at least one sidelink resource pool, and
• wherein the configuration information further includes information on a communication range requirement for each of the at least one sidelink resource pool.

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

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• obtain configuration information on at least one sidelink resource pool, wherein the configuration information includes information on whether a physical sidelink feedback channel (PSFCH) is configured for each of the at least one sidelink resource pool,
• in case that a sidelink hybrid automatic repeat request (HARQ) feedback is enabled, identify any sidelink resource pool configured with the PSFCH, among the at least one sidelink resource pool, and
• transmit, via the transceiver, sidelink data on a physical sidelink shared channel (PSSCH) based on the identified sidelink resource pool,
• wherein the configuration information further includes information on a communication range requirement for each of the at least one sidelink resource pool.
