Abstract

A mobile communication system according to the embodiment supports cellular communication in which a data path passes through a network and D2D communication that is direct device-to-device communication in which a data path does not pass through the network. A frequency division multiplexing scheme is applied to the cellular communication and a code division multiplexing scheme is applied to the D2D communication. The network assigns a spread code having orthogonality to a user terminal in response to a request from the user terminal. The user terminal performs the D2D communication by using the spread code assigned by the network.
