Abrégé
(EN)
The invention proposes a method and an apparatus for the radio transmission of user data, arranged in data words of a defined length, in time-division multiplex frames having active time slots in which data are transmitted and inactive time slots in which no data are transmitted. The user data are stored temporarily in a memory at a first data rate, and are read out from the memory and converted into the time-division multiplex frames at a second, greater data rate. During the time period from the beginning of an active time slot to the beginning of the subsequent active time slot, n (n = a whole number >= 1) data words of the user data are thereby respectively stored. By means of the synchronization of the storing and the reading out of the user data, these data can be transmitted with the smallest possible delay in an arbitrarily selected time slot of the time-division multiplex frame.
