A method of frequency re-planning in a wireless communication system is disclosed, wherein the wireless communication system (100) is arranged to support communication for a plurality of mobile stations (112-115) via a plurality of cells. The method comprises the generation of channel/interference penalties based upon measurement reports. However, for a first cell having one or more neighbouring co-channel cells for which measurement reports are unavailable, channel/interference penalties are estimated for the one or more neighbouring co-channel cells. These estimates are based upon the interference levels of common neighbours of the first cell and the one or more neighbouring co-channel cells.

L'invention concerne un procédé de replanification des fréquences dans un système de télécommunication sans fil, ce système (100) de télécommunication sans fil étant conçu pour prendre en charge les communications d'une pluralité de stations mobiles (112-115) en utilisant une pluralité de cellules. Ce procédé consiste à produire des pénalités canal/interférence fondées sur des relevés de mesures. Toutefois pour une première cellule entourée d'une ou de plusieurs cellules adjacentes partageant le même canal et pour lesquelles les relevés de mesures ne sont pas disponibles, les pénalités canal/interférence pour cette ou ces cellules adjacentes partageant le même canal sont estimées. Ces estimations sont fondées sur les niveaux d'interférence des cellules adjacentes communes à la première cellule et à la ou aux cellules adjacentes partageant le même canal.
