Abstract
There is provided a method for removing interference between a femto-cell and a macro-cell, comprising: allocating communication resources to a plurality of femto-cell user devices; receiving uplink signals between a plurality of the macro-cell user devices and a macro-cell base station from the plurality of the macro-cell user devices; detecting a high interference indicator (HII) from the uplink signals; deciding a macro-cell user device, which has transmitted the high interference indicator, as an interference subject user device; extracting channel state information (CSI) from the uplink signal received from the interference subject user device; and changing and allocating the communication resource allocated to the femto-cell user device based on the extracted channel state information.
