SYSTEM, UNIT AND METHOD OF FREQUENCY RE-PLANNING

摘要

A method of frequency re-planning in a wireless communication system 100 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 (C/I) 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 (C/I) 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. An intelligent optimisation system (IOS) 172 is coupled to an operations and management centre (OMC) 146 and base station controllers (BSC) 136-140 to set an initial frequency re-use plan and to generate a C/I penalty matrix based upon measurement reports and the estimated values. The generated C/I penalty matrix is used for frequency re-planning.
