The device may perform an interference analysis on the sectors' physical resource blocks (PRBs) and receiving branches, of the interference data, to generate analysis results, and may determine interference associated with co-located sectors of the set of sectors. The device may identify neighbor sectors based on the interference, and may compare PRBs of the set of sectors with PRBs of the neighbor sectors to generate comparison results. The device may identify a particular sector that is the most impacted sector when compared to its neighboring and co-located sectors, associated with an interference source, based on the comparison results. ## Claims ### Claim 1 A method, comprising: performing, by a device, an interference analysis on interference data for a set of sectors;
