OTHER CELL INTERFERENCE ESTIMATION

摘要

The disclosure relates to a method and a node for estimating other cell interference in a radio network node (300) providing an own cell serving at least one radio device in a radio network. The method comprises measuring a load utilization, relating to the load utilized by said at least one radio device. The method also comprises estimating a load utilization probability based at least on the measured load utilization, a previously estimated load utilization probability and a previously estimated interference-and-noise sum. The method also comprises estimating an interference-and-noise sum based at least on the measured load utilization, a measured received total wideband power (RTWP) the estimated load utilization probability and the previously estimated interference-and-noise sum. The method also comprises checking whether the estimated load utilization probability and/or estimated interference-and-noise sum and/or any algorithm value derived from any of the estimates, is within a predefined range.
