Title
(EN) Apparatus and Method for Reactive Inter-Cell Interference Coordination
Abstract
(EN)

A network node (10) communicates with user equipments, UEs, in a cell served by the network node. The network node receives measurement reports from its UEs and obtains therefrom statistics (S1). The network node receives an interference overload indicator, IOI, from a neighboring network node having a neighboring cell (S2) that may prompt making the determination. The network node uses the statistics to determine whether transmissions in the cell are or will be a likely cause of interference to the neighboring cell (S3). The network node then determines whether to take action with respect to one or more of the UEs based on the determination of whether transmissions in the cell are or will be a likely cause of interference to the neighboring cell (S4).
