Abstract

The invention relates to a method that includes transfer of data encoded on the basis of a first encoding scheme via an interface between a baseband assembly and a radio-frequency assembly of a mobile radio transceiver. The method further includes transfer of a data sequence which is encoded on the basis of the first encoding scheme and which identifies a change of encoding scheme from the first encoding scheme to a second encoding scheme. Lastly, the method includes transfer of data encoded on the basis of the second encoding scheme via the interface.
