Patent ID: 8280394

Claim:
A method in a unit connected to or integrated in a base transceiver station of a communication system, said base transceiver station serving a first cell being part of a cluster of neighbouring cells served by base transceiver stations, said method for determining impact values for transmissions in said first cell on the interference in neighbouring cells of said cluster, and said method comprising: signalling information on at least the total estimated neighbour cell interference power P f i Neighbour and the own cell power P f i Own for frequency subsets of tones f i to neighbouring cells in said cluster; and calculating for each frequency subset of tones f i a vector of impact values k f i from at least a regression vector comprising received values of the own cell powers P f i Own of neighbouring cells in said cluster and from received values of said estimated neighbour cell interference power P f i Neighbour , whereby each impact value describes the interference impact of transmissions in said first cell on a respective other cell in said cluster.
