APPARATUS AND METHOD FOR MITIGATION/REMOVAL OF INTERFERENCE BETWEEN MACROCELL AND FEMTOCELL

摘要

The invention relates to a method for removing interference between a macrocell and a femtocell, which involves allocating a communication resource to a femtocell user terminal, receiving an uplink signal between a macrocell user terminal and a macrocell base station, detecting a high interference indicator from the uplink signal, determining that the macrocell user terminal which has transmitted the high interference indicator is an interference target user terminal, extracting channel state information from the uplink signal received from the interference target user terminal, and changing the communication resource allocated to the femtocell user terminal based on the extracted channel state information and allocating the changed communication resource.
