摘要:
Provided are a method and an apparatus for releasing a blank zone by a macro base station in a wireless communication system. The macro base station: receives channel information from a macro terminal that is serviced therefrom; determines based on the channel information whether or not a downlink blank zone allocated to a resource zone of a femto bas station is released; and transmits downlink blank zone release information to the femto base station if the downlink blank zone is supposed to be released. The downlink blank zone is a resource zone which restricts the downlink transmission, among all the resource zones used by the femto base station. The channel information may be the information about the distance between the femto base station and the macro terminal.
