Abstract

This method of allocating a downlink frequency band in a coordinated multi-point system based on multi-cell joint signal processing, this method comprises: - a step (E10) of clustering said cells for determining at least a collaborative set of cells; and - a step (E20) of classifying the user equipments in said cells in a category of center user equipments (CCU) or in a category of edge user equipments (CEU); said center user equipments being served independently and said edge user equipments being jointly served by said collaborative set of cells, said method further comprising, at each transmission time interval : - a step (E30) of dynamically allocating to each category (CCU, CEU) part of the downlink frequency spectrum available for said system according to the number of user equipments in each category; - a step (E40) of scheduling the physical resource block allocated to said user equipments in their respective frequency band according to a priority (PFi) taking into account a channel state (Hi) and a traffic condition (Vi, R'i) of said user equipments.
