Abstract:
1. A method for neighbor cell interference estimation comprising: measuring a total uplink power per subset of tones; measuring a own-channel power per the same subset of tones; calculating an auxiliary power quantity for each subset of tones as the total uplink power per subset of tones minus the own-channel power per subset of tones minus the leakage of power from other subsets of tones; combining the auxiliary power quantities for all subsets of tones to obtain a total auxiliary wideband power for the entire uplink band; calculating a thermal noise floor measure based on said total auxiliary wideband power quantity; and dividing said calculated thermal noise floor measure into sub noise floor measures for each subset of tones, said dividing dependent on the bandwidth of each subset of tones, for obtaining a neighbor cell interference measure for each subset of tones from at least said sub noise floor measures.
