Apparatus and method for controlling inter-cell interference between femtocells and macrocells

摘要

A method for controlling inter-cell interference may include receiving a measured uplink interference level through a first backhaul link; determining a transmit power level based on the measured uplink interference level; and sending through a second backhaul link the transmit power level for reconfiguring either a user equipment or a femtocell eNodeB. From the downlink perspective, it may include measuring a downlink interference; and reporting the level of the downlink interference to an ICIC server using a backhaul link. In one example, it may include receiving a measured downlink interference through a first backhaul link; determining a transmit power level based on the measured downlink interference; and sending a message comprising the transmit power level to a femtocell eNodeB using a second backhaul link.
