Abstract: 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.

Abstract: 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.
