Abstract

See full text

The present invention pertains to methods and devices relating to neighbor cell interference estimation and handling in cellular communication networks. According to one aspect, there is provided a method for interference handling performed in a radio network node for a cellular communication network. The method comprises measuring a received total wideband power, RTWP, and a load utilization experienced at the radio network node. The method further comprises performing a vector estimation of neighbor cell interference experienced at the radio network node based on the measured RTWP and the measured load utilization. The vector estimation comprises decomposition into at least two scalar component estimations. The method may further comprise obtaining and using tabulated computation support information, which is used when performing the vector estimation of neighbor cell interference. According to another aspect, there is provided a radio network node adapted to perform the method.
