Abstract

Method and arrangement in a Vector Control Entity for efficient selection of which crosstalk to cancel when applying partial vectoring in a DSL communication system. The method comprises calculating a respective crosstalk effect indicator, CEIij, for the crosstalk from each line j of a plurality J of lines in a vectoring group, to a plurality of tones Si of a line i in the vectoring group, based on the strength of the crosstalk from each line j to line i, and thus providing one CEli-value, associated with the plurality Sj of tones, per line j. The method further comprises allocating partial-vectoring resources to cancellation of crosstalk, based on the calculated CEIs. The arrangement is adapted to enable the performance of the above described method.
