An improved radio link architecture for digital wireless communication systems which is characterized by the use of information and signalling channels on a number of RF carriers, thereby providing common signalling channels for call set-up and control functions. A first group of RF carriers are allocated as traffic channels between base stations and subscriber terminals. Each RF carrier in the first group comprises at least one traffic channel. A second group of RF carriers is allocated for providing common signalling channels between the base stations and the subscriber terminals. Each RF carrier having common signalling channels operates in time division multiple access mode, and each common signalling channel being time division duplexed.

L'invention porte sur une architecture améliorée de liaisons radioélectriques pour des systèmes numériques de communication sans fil caractérisés par l'utilisation de canaux d'information et de signalisation correspondant à un certain nombre de porteuses RF, prévoyant ainsi des canaux de signalisation communs pour les fonctions d'établissement et de gestion des communications. Un premier groupe de porteuses RF est alloué comme canaux de trafic entre les stations de base et les terminaux d'abonnés. Chaque porteuse RF dans le premier groupe forme au moins un canal de trafic. Un second groupe de porteuses RF est alloué pour fournir des canaux de signalisation communs entre les stations de base et les terminaux d'abonnés. Chaque porteuse RF ayant des canaux de signalisation communs fonctionne en mode d'accès multiple par répartition dans le temps, et chaque canal de signalisation commun fait l'objet d'un duplexage par répartition dans le temps.
