Patent ID: 8903405

Claim:
A communication method of a micro base station for interference control, the communication method comprising: determining whether to perform a handover of macro user equipment from a macro base station to a micro base station based on interference from the macro user equipment served by the macro base station to micro user equipment served by the micro base station; searching for an index of a resource allocable to the macro user equipment; transmitting, to the macro base station, a handover request message including the index of the resource allocable to the macro user equipment; receiving an indication as to an interference control mode determined by the macro base station; and performing the handover of the macro user equipment based on the received indication, in response to the handover request message, wherein the macro base station selects the interference control mode from among at least four interference control modes comprising a first mode to perform the handover of the macro user equipment from the macro base station to the micro base station, a second mode to perform Inter-Cell Interference Coordination (ICIC) on the macro user equipment, a third mode to perform the handover from the macro base station to the micro base station and the ICIC on the macro user equipment, and a fourth mode to perform a Cooperated MultiPoint (CoMP) scheme on the macro user equipment by the micro base station and an adjacent base station that is adjacent to the micro base station.
