Method and system for realising a fast control channel in a cellular radio network

摘要

Signalling information is conveyed from a transmitting device ( 101 ) to a receiving device ( 102 ) in a cellular radio network where user data transmission takes place on a traffic channel in discrete transmission bursts ( 111-120; 211-220; 310-313 ) consisting of consecutive symbols. A piece of signalling information is formatted into symbols which are transmitted as a block of consecutive symbols (FACCH) in a certain transmission burst of a traffic channel. It is also indicated within said certain transmission burst that it contains symbols carrying signalling information.
