Title
(EN) METHOD OF SUBCARRIER ALLOCATION IN AN OFDMA-BASED COMMUNICATION NETWORK AND NETWORK
(FR) PROCÉDÉ D’ATTRIBUTION DE SOUS-PORTEUSE DANS UN RÉSEAU DE COMMUNICATION BASÉ SUR OFDMA ET RÉSEAU
Abstract
(EN)
A method of subcarrier allocation in an OFDMA-based communication network, wherein said network includes a network controller and a number of base stations, wherein said network is divided into different cells and/or sectors, and wherein subchannels are generated by forming subsets of active orthogonal subcarriers of the OFDMA frame structure, is characterized in that said base stations measure the traffic load and/or the interference from neighboring and/or other cells and/or sectors, wherein an allocation of said subchannels to said cells and/or sectors is performed on the basis of the results of said measurements. Furthermore, a network applying OFDMA technology is disclosed.
(FR)
L’invention concerne un procédé d’attribution de sous-porteuse dans un réseau de communication basé sur OFDMA, ledit réseau comprenant un contrôleur de réseau et un certain nombre de stations de base, ledit réseau étant divisé en différentes cellules et/ou secteurs et des sous-canaux étant générés en formant des sous-ensembles de sous-porteuses orthogonales actives de la structure de trame OFDMA. L’invention est caractérisée en ce que lesdites stations de base mesurent la charge de trafic et/ou les interférences en provenance de cellules et/ou de secteurs voisins et/ou autres, une attribution desdits sous-canaux auxdits secteurs et/ou cellules étant exécutée sur la base des résultats desdites mesures. En outre, un réseau appliquant une technologie OFDMA est décrit.
