Abstract

SELON L'INVENTION, DES PARAMÈTRES DE SYNCHRONISATION ET UNE IDENTITÉ D'UN GROUPE DE CELLULES PARTICULIER PARMI UN CERTAIN NOMBRE DE GROUPES DE CELLULES SONT INDIQUÉS DANS UN SIGNAL TRANSMIS DANS UN SYSTÈME DE COMMUNICATION CELLULAIRE PRÉSENTANT UNE TRAME RADIO DANS UNE COUCHE PHYSIQUE, LA TRAME RADIO COMPRENANT UN CERTAIN NOMBRE D'INTERVALLES DE TEMPS. DANS UN INTERVALLE DE TEMPS CONNU PARMI LES INTERVALLES DE TEMPS, UN SIGNAL DE SYNCHRONISATION, S1, EST TRANSMIS, LEQUEL COMPREND UNE PAIRE DE SÉQUENCES (I) AGENCÉES SELON UN PREMIER ORDRE. DANS UN AUTRE INTERVALLE DE TEMPS CONNU PARMI LES INTERVALLES DE TEMPS, UN SIGNAL DE SYNCHRONISATION, S2, EST TRANSMIS, LEQUEL COMPREND LA PAIRE DE SÉQUENCES (II) AGENCÉES SELON UN SECOND ORDRE. LA PAIRE SÉLECTIONNÉE DE SÉQUENCES EST UNIQUEMENT IDENTIFIÉE À L'AIDE DU GROUPE DE CELLULES PARTICULIER, ET LE PREMIER ORDRE DES SÉQUENCES EST UTILISÉ UNIQUEMENT POUR LA TRANSMISSION DANS L'INTERVALLE DE TEMPS CONNU PARMI LES INTERVALLES DE TEMPS, ET LE SECOND ORDRE DES SÉQUENCES EST UTILISÉ UNIQUEMENT POUR LA TRANSMISSION DANS LEDIT AUTRE INTERVALLE DE TEMPS CONNU PARMI LES INTERVALLES DE TEMPS.
