Abstract
The invention relates to a mobile system in which the radio interface rate of a traffic channel and the intermediate rate of a transmission channel restrict the number of bits available for the transmission of terminal interface statuses (S) network independent clocking (N) and subchannel numbering (#) of a multichannel data link. In the invention the bits form a subframe (n . . . n+10) and the status and control information are multiplexed inside successive subframes in a superframe structure (SUPERFRAME). In other words the capacity of the bits available for the control information is shared by various kinds of control information by means of the superframe structure.
