Abstract

The present invention relates to a method and arrangement in a wireless communication system, e.g. an evolved UMTS Terrestrial Radio Access Network, for improved scheduling and admission control of the uplink by providing an improved determining of power-related quantities, e.g. neighbor cell interference levels, for specific tones and providing more accurate recursive estimation of noise-related quantities, e.g. noise floor power estimates, for specific tones. The method and arrangement obtains a neighbor cell interference measure for each subset of tones from at least a noise floor measure for each subset of tones based on combined power quantities from the total uplink power per subset of tones and dividing said noise floor measure into sub noise floor measures for each subset of tones, said dividing dependent on the bandwidth of each subset of tones.

First claim

The invention claimed is:

1. A method of estimating neighbor cell interference in a node for a wireless communication system, comprising:
measuring a total uplink power per a subset of tones;
measuring an own channel power per the subset of tones, wherein the subset of tones includes at least one tone;
combining for all subsets of tones auxiliary power quantities from at least the total uplink power per subset of tones to form a total auxiliary wideband power for an entire upl…
