Abstract: A cross carrier scheduling method is provided by a terminal. The terminal receives a control element including cross carrier scheduling configuration information from a base station, and sets a scheduling cell of a secondary cell in accordance with the cross carrier scheduling configuration information. The terminal starts to monitor scheduling information of the secondary cell at the scheduling cell from a time predefined between the base station and the terminal.

Abstract: According to an exemplary embodiment of the present invention, a master base station selects a target serving cell in which a state is changed, among the serving cells of at least one slave base station set in the terminal, generates a MAC control element which instructs a state change of the target serving cell, and then directly transmits the MAC control element to the terminal in the case of an uplink asynchronous state between the target slave base station managing the target serving cell and the terminal.

Abstract: A method of providing a multicast service is provided by a terminal in a terminal-to-terminal direct communication. The terminal transmits a service start request message requesting a start of a multicast service to a multicast server, and receives a service start response message including a result of permitting a start request from the multicast server. The terminal receives, via a base station, resource information of a resource which a multicast coordinator allocates to the multicast service in accordance with a request of the multicast server, and transmits multicast service data based on the resource information.

Abstract: A base station of a carrier aggregation system performs interference control of a first component carrier in which interference exceeds a threshold value among a plurality of component carriers based on an ABS pattern and changes the first component carrier to an available new component carrier, when interference of the first component carrier exceeds a threshold value after the interference control is performed.

Abstract: A method in which a base station manages information for D2D communication, which is direct communication between terminals, is provided. The base station receives a first message that requests a configuration of a first open discovery service that searches for a first terminal and at least one terminal to perform D2D communication. The base station determines whether a resource to allocate to the first terminal exists. The base station stores first information for providing the first open discovery service based on the determination result.
