ABSTRACT:
A method for indicating a change in coding rate so as to maintain synchronization between a communication system and a mobile station. A mobile station can request either to increase or decrease the degree of channel coding. The system can grant the request and send an indication to the mobile station indicating the new degree of coding. The indication is provided outside the field in which the coding rate is going to be changed. A modulation symbol alphabet can also changed.
