Abstract
To allow the synchronization at multiframe level of a mobile terminal on a traffic down path which exhibits a multiframe structure with a determined number L of useful data frames, the base stations send signalling frames respectively associated with each useful data frame of the traffic down path and each containing a signalling code. The number N of distinct values of the signalling codes which are usable by the mobile terminal to recover the synchronization at multiframe level is less than L. These values are apportioned to the associated signalling frames in such a way that there exist two integers P and Q, not both equal to unity, such that P×Q of these values, respectively contained in P sequences of associated signalling frames each comprising Q signalling frames respectively associated with any Q consecutive useful data frames of a multiframe, form a unique word.
