1. A method performed by a gNB central unit (gNB-CU) in a wireless communication system, the method comprising:
receiving, from a User Equipment (UE), a request message requesting resources for sidelink communication;
transmitting, to a gNB distributed unit (gNB-DU), a UE Context Request message requesting vehicle-to-everything (V2X) resources based on a type of the UE;
receiving, from the gNB-DU, a UE Context Response message including information regarding a V2X resource; and
transmitting, to the UE, a response message including the information regarding the V2X resources,
wherein the type of the UE is one of a pedestrian UE or a vehicle UE,
wherein the gNB-CU is a logical node constituting a gNB that hosts a radio resource control (RRC) layer, a Service Data Adaptation Protocol (SDAP) layer, and a packet data convergence protocol (PDCP) layer of a network node including the gNB-CU and the gNB-DU, and
wherein the gNB-DU is a logical node constituting a gNB that hosts a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a physical layer of the network node.
