The present invention relates generally to the field of signaling of information, and particularly to a method and a system for signaling information in transmission systems. Methods for signaling information in transmission systems do have certain disadvantages, like the use of an additional channel for signaling or the use of a large number of bits for signaling. The present invention facilitates highly protected and highly reliable signaling requiring only a minimum of bits by inserting an individual signaling information into individual frames and by additionally partitioning signaling information and inserting the partitioned signaling information into different frames, i. e. spreading the signaling information.
