Abstract
Method for transmitting an information representative of the number of spreading codes allocated to the mobile stations in communication with a base station of a mobile telecommunication system. The method forms a word to be transmitted, the content of which is representative of the number of spreading codes allocated. In each transmission burst a general midamble resulting from the sum of selected midambles among all the available midambles is included. The selection is done by the base station in relation with the transmitted word so that a selected midamble corresponds to a binary element of the transmitted word equal to a first value and a non-selected midamble corresponds to a binary element of the transmitted word equal to a second value. A received word is considered, the elements of which are in a one-to-one relationship with the temporal positions of the estimations respectively corresponding to the available midambles.
