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.
