METHOD FOR COORDINATING INTER-CELL INTERFERENCE IN HETEROGENEOUS NETWORK AND HETEROGENEOUS NETWORK

摘要

The present invention provides a method for coordinating inter-cell interference in a heterogeneous network, and a heterogeneous network. The method comprises configuring as a cooperative group M normal base stations and low power nodes covered by the base stations in said heterogeneous network, acquiring multiple states for said cooperative group by combining mute/non-mute states in the bandwidth of said M normal base stations, feeding back at least one first CQI to said normal base stations from a user of each normal base station, feeding back one or more second CQI to said low power nodes from a user of each low power node, and setting the mute/non-mute states in the bandwidth for data transmission according to a cooperative group state corresponding to the highest system performance by estimating the performance of the cooperative group on the basis of the first CQI and the second CQI.
