One embodiment of the present invention provides an apparatus comprising a transceiving unit and a control unit, and a communication method using the same, wherein the transceiving unit is configured to perform communication with at least one network node in a macro cell, the macro cell comprising at least one small cell and communicating in an FDD mode, and wherein the control unit is configured to control the small cell to communicate in a TDD mode, generate control information for preventing the occurrence of handover when a terminal moves between the small cells within the macro cell, and perform control to transmit the control information to the terminal.

Method and apparatus for carrier aggregation communication in wireless communication system

A centralized scheduling method and apparatus is provided for minimizing inter-cell interference in the wireless communication system adopting femto-eNB-based service coverage expansion (range expansion). The method includes establishing, by a server, a connection with at least one base station, collecting channel information between the at least one base station connected to the server and terminals, determining interfering base stations causing interference to each terminal based on the channel information, and selecting the terminals to be scheduled in consideration of the interfering base stations.

Centralized-scheduling method and apparatus for inter-cell interference coordination in heterogeneous network

A method of supporting fast sub-cell switching by a sub-cell included in a macro coverage in a wireless communication system is provided. The method includes receiving multiple pieces of feedback information on multiple sub-cells from a User Equipment (UE), extracting channel quality indicators from the multiple pieces of received feedback information, respectively, comparing values of the extracted channel quality indicators, and determining, based on a result of the comparison of the values of the extracted channel quality indicators, whether to perform fast sub-cell switching of the UE.
