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: A carrier aggregation-based interference control method and apparatus for small base stations are disclosed. The present invention comprises setting a primary component carrier (PCC) as a first carrier and setting a secondary component carrier (SCC) as a second carrier, monitoring a signal-to-interference plus noise ratio (SINR) of the first carrier or the second carrier, and determining whether the SINR of the first carrier is smaller than a predetermined threshold.

Abstract: A self-organizing network (SON) and an operating method of the SON. An operating method of a base station in the SON includes receiving a parameter setting message including a first version identification (ID) and setting values of parameters, storing the setting values to match the first version ID, and setting parameters of the base station based on the setting values.

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: 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.
