Abstract
A method for using channels in a time-division multiple access radio system which includes at least one base station and at least one mobile station and which operates on one or more carrier frequencies per base station. The carrier frequencies are divided into a plurality of physical channels including time slots and a predetermined number of time slots forming a frame. One of the base station's carriers is a main carrier on which a main control channel operates. At least one physical channel of the main carrier is used for transmitting broadcast control channels and the last one of said at least one physical channel is allocated to a traffic channel only if the base station does not have other physical channels available.
