Abstract

A method detects a bandwidth that is transmitted by a transmitter in a radio communications system, which is based on transmission frames. The transmission frames comprise a fixed time extension and a variable spectral extension. The transmission frames consist of a plurality of sub-units. Each sub-unit of the transmission frames contains a control channel, which is subdivided into two sub-control channels. The two sub-control channels are arranged at the spectral edges of the sub-units of the transmission frames. The transmitted bandwidth is investigated by determining the spectral extension of the transmission frame. The spectral extension of the transmission frame is determined by determining the spectral position of the sub-control channels in the sub-units of the transmission frames.
