Abstract
In a radiocommunications system having physical channels each including at least one logical channel, the invention proposes transmitting both the means for acquiring and tracking synchronization and the system information addressed to user stations in a single logical channel referred to as the 'synchronization' channel. For this purpose, the synchronization channel carries a repeated detection word (1) together with system information (2) between repeats of the detection word. The system information is subjected to spreading prior to being transmitted over the synchronization channel. The invention makes it possible to limit the amount of system resources that are devoted to providing the functions of synchronization and of broadcasting system information.
