Title (EN) METHOD AND SYSTEM FOR COMMUNICATING COOPERATIVELY BETWEEN BASE STATIONS AND MOBILE STATIONS IN A WIRELESS CELLULAR NETWORK
(FR) PROCÉDÉ ET SYSTÈME DE COMMUNICATION COOPÉRATIVE ENTRE DES STATIONS DE BASE ET DES STATIONS MOBILES DANS UN RÉSEAU CELLULAIRE SANS FIL
Abstract: front page image
(EN)A method and system communicates cooperatively between base stations and mobile stations in a wireless cellular network. At least two mobile stations are detected in a handover region. A diversity set is established for each mobile station in the handover region. Each diversity set identifies at least two base stations that can communicate with the associated mobile station. The at least two base stations and the at least two mobile stations are combined into members of a cooperation set. A resource is allocated to selected members of the cooperative set. The selected members are notified of the allocated resource. Then, the selected base stations of the cooperation set communicate concurrently with the selected mobile stations using the same allocated resource.
(FR)L'invention concerne un procédé et un système qui communiquent de manière coopérative entre des stations de base et des stations mobiles dans un réseau cellulaire sans fil. Au moins deux stations mobiles sont détectées dans une région de transfert intercellulaire. Un ensemble de diversité est établi pour chaque station mobile dans la région de transfert intercellulaire. Chaque ensemble de diversité identifie au moins deux stations de base qui peuvent communiquer avec la station mobile associée. Les deux stations de base ou plus et les deux stations mobiles ou plus sont combinées en des éléments d'un ensemble de coopération. Une ressource est allouée aux éléments sélectionnés de l'ensemble de coopération. Les éléments sélectionnés sont informés de la ressource allouée. Ensuite, les stations de base sélectionnées de l'ensemble de coopération communiquent simultanément avec les stations mobiles sélectionnées en utilisant la même ressource allouée.
