Abstract: Disclosed is a method for a vehicle to communicate with a network in a wireless communication system. The method may comprise: receiving a message related to a parking lot from the network; transmitting, to the network, a message for requesting a reservation for a specific parking space from among at least one parking space in the parking lot; and receiving a message including the spatial coordinates of the specific parking space. In particular, the message for reservation includes type information of the vehicle, and the spatial coordinates of the specific parking space may be dynamically determined on the basis of the type information of the vehicle and type information of the at least one parking space.
