The present disclosure relates to a method for operating a first terminal in a wireless communication system, wherein the first terminal may transmit a beam scheduling request message to a second terminal. The beam scheduling request message includes transmission beam direction information of the first terminal and receiving beam schedule information of the first terminal, and the receiving beam schedule information of the first terminal may include at least one of receiving beam timing information of the first terminal and receiving resource pool information of the first terminal. In addition, the first terminal may receive a beam scheduling confirm message from the second terminal. The beam scheduling confirm message includes transmission beam direction information of the second terminal and receiving beam schedule information of the second terminal, and the receiving beam schedule information of the second terminal may include at least one of receiving beam timing information of the second terminal and receiving resource pool information of the second terminal. In addition, the first terminal may transmit data to the second terminal based on the beam scheduling confirm message.
