Abstract

The invention concerns a method for beam coordination between a first base station (M1) and a second base station (P1), wherein interfering beams (B2-B4) transmitted from the first base station (M1) are determined based on measured reference signals, dependent on a ranking of interfering beams (B2-B4) which shall be restricted in use, a restriction of a use of radio resources in the first base station (M1) in at least one ranked interfering beam (B3) is performed, and user terminals (UE1, UE2) served by the second base station (P1) are scheduled on radio resources which are restricted in use in the first base station (M1) in said at least one ranked interfering beam (B3), a base station and a user terminal therefor.
