Apparatus and method for controlling inter-cell interference between femto and macro cells

摘要

An apparatus and method for controlling inter cell interference to detect and measure uplink interference and to use a backhaul link to report the level of uplink interference to an inter cell interference coordinated (ICIC) server . In one example, the apparatus and method can receive a measurement uplink interference level via a first backhaul link and determine a transmit power level based on the measurement uplink interference level, and a user device or femtosecond It may include sending a transmit power level via a second backhaul link to reconfigure any of the cell e nodes B. From the downlink point of view, the apparatus and method include measuring downlink interference and reporting back level of downlink interference to an ICIC server using a backhaul link. In one example, the present apparatus and method receive measurement downlink interference through a first back hole link and measureDetermining the transmit power level based on the unlink interference and sending the message with the transmit power level to the femtocell e node B using a second backhaul link.
