Method of cellular digital radiocommunication in a time division multiple access system using a geographical cell network having mobile stations (SM1 to SM22) passing therethrough, a base station being assigned to each of the cells. A mobile station communicates through the base station associated with the cell in which it is located. The frames of the uplink transmission direction of the mobile stations to the base station comprise at least one shared time interval (IT6) which is assigned to at least two separate mobile stations (SM7 to SM22). According to the invention, for each shared time interval (IT6), the system has a list of active mobile stations, an active mobile station being a mobile station in which said shared time interval is assigned and meets at least one predetermined selection criterion. For each frame of the uplink transmission direction, the system associates, with each shared time interval, a selected mobile station according to a predetermined strategy from the list of active mobile stations associated with said shared time interval.
L'invention concerne un procédé de radiocommunication numérique cellulaire, dans un système AMRT mis en oeuvre au sein d'un réseaude cellules géographiques parcouru par des stations mobiles (SM1 à SM22), une station de base étant associée à chacune des cellules, une station mobile communiquant par l'intermédiaire de la station de base associée à la cellule dans laquelle elle se trouve, les trames du sens de transmission montant, des stations mobiles vers la station de base, comprenant au moins un intervalle de temps partagé (IT6) qui est alloué à au moins deux stations mobiles distinctes (SM7 à SM22). Selon l'invention, pour chaque intervalle de temps partagé (IT6), le système possède une liste des stations mobiles actives, une station mobile active étant une station mobile à laquelle est alloué cet intervalle de temps partagé et répondant à au moins un critère prédéterminé de sélection, et, pour chaque trame du sens de transmission montant, le système associe à chaque intervalle de temps partagé une station mobile choisie, selon une stratégie prédéterminée, parmi la liste des stations mobiles actives associée à cet intervalle de temps partagé.
