Abstract
The present invention discloses a method and an apparatus for suppressing inter-cell interference. The method includes: obtaining edge channels whose signal interference ratio (SIR) is above a preset threshold from edge channel group to constitute a first candidate channel set; selecting an edge channel of the lowest correlation as a tier-1 channel; obtaining central channels whose SIR are above a preset threshold from central channel group to constitute a second candidate channel set; selecting a central channel of the lowest correlation as a tier-2 channel; and comparing SIRs of the tier-1 channel and the tier-2 channel and assigning the channel of a higher SIR to an edge terminal in the local cell. The present invention may suppress inter-cell interference and reduce the waste of channel resources.
