Radio transmission system including a master station and one or more terminal stations. All the information transmitted are organized in bursts, some of which carry user data and some other transport control information. According to the invention: all the bursts transporting user data, or information bursts, have the same duration on the channel, said duration being labelled "time slot", and are suitable to carry an information field of elementary dimension. the bursts carrying the control information have the duration of one slot or of a slot fraction. The transmission system according to the invention can therefore be defined "slot based" system since each burst contains all the information necessary for its correct interpretation and the duration of said bursts is fixed either the burst contains control information or the burst contains useful data. The present invention enables to obtain considerable advantages in terms of synchronisation speed, robustness, efficiency and speed of the management protocols of the shared use of the channel (function of medium access control or MAC). |
