To provide a method for radio transmission of a cellular mobile radio communication network 1.

The cellular mobile radio communication network 1 has a hierarchical radio cell structure consisting of small radio cells 2 and at least one larger radio cell 3 superposed on the small radio cells 2. This invention proposes that the cellular mobile radio communication network 1 having the hierarchical radio cell structure attains real time radio transmission, in details, real time data transmission and executes the real time radio transmission via at least one superposed larger radio cell 3 in order to improve the transmission quality of the real time radio transmission. The execution via the smaller radio cells 2 is preferred for non real time data transmission. In the case of furthermore improving the transmission quality of the non real time data transmission, this invention proposes that data transmission is interrupted until a measured interference signal is below a predetinable interference threshold.
