Radio link architecture for wireless communication systems

Abstract

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.
