8. The method of claim 1 , wherein the 3D media data is transmitted in real-time.
9. A method performed by a second terminal in a wireless communication system, the method comprising:
identifying capabilities of at least one component device which is connected to the second 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 indicating an entry point corresponding to the XR service;
establishing a session for the XR service, wherein the session for the XR service is associated with the entry point;
receiving, from a first terminal, three-dimensional (3D) media data for the XR service, wherein the 3D media data is processed by a cloud, based on a capability of the second terminal;
performing at least one processing on the 3D media data; and
rendering the processed 3D media data on the second terminal.
10. The method of claim 9 , further comprising:
determining at least one processing to be performed by the cloud, based on the capability of the second terminal.
11. The method of claim 10 , further comprising:
requesting the cloud to perform the determined at least one processing.
