Abstract:
1. A method of generating neighbor lists in a radio communication network comprising user terminals and base stations defining sectored or omnidirectional radio cells, where communication between user terminals and base stations is arranged to take place over radio channels, the method comprising the steps of: receiving radio channel measurements from at least some of the user terminals; creating a first table by using the measurements received from the user terminals, the first table comprising for at least some of the user terminals the corresponding radio channel measurement in relation to different radio cells; processing the first table to generate a cell coupling matrix comprising a radio coupling figure for each of a plurality of pairs of cells in the network, wherein said processing the first table to generate the cell coupling matrix comprises generating a distribution of relative signal strengths for each of the plurality of pairs of cells, wherein the relative signal strengths correspond to the individual measurements stored in the first table, and wherein said processing the first table to generate the cell coupling matrix comprises deriving the radio coupling figure for each of the plurality of pairs of cells from the respective distribution of relative signal strengths; and for a certain cell obtaining a neighbor list by determining the radio channel neighbors to be the cells of which the coupling figure with the cell in question is greater than a given threshold.
