1. A method performed by a first terminal in a wireless communication system, the method comprising:
identifying capabilities of at least one component device which is connected to the first terminal;
receiving, from a server, information indicating a list of extended reality (XR) services and configuration information for the XR services;
determining, an XR service among the list of XR services, based on the capabilities of the at least one component device and the configuration information for the XR services;
receiving, from the server, information of an entry point corresponding to the XR service;
establishing a session for the XR service based on the capabilities of the at least one component device, wherein the session for the XR service is associated with the entry point;
determining a first pre-processing performed by a cloud on three-dimensional (3D) media data for the XR service that is acquired by the at least one component device, based on the capabilities of the at least one component device;
performing a second pre-processing on the 3D media data; and
transmitting, to a second terminal, the pre-processed 3D media data, based on the first pre-processing and the second pre-processing.
