- In this paper we identify and describe the requirementsand challenges of next generation mobile communicationssystems. The so-called fourth generation (4G) aims at throughput rates of more than 100 MBit=s outdoors with high mobility and 1 GBit=s indoors. This requires new advanced techniques in the air interface of such a system. We outline new possible techniques and introduce a future basic physical layer concept. The adaptivity to the channel of all the modules in such a possible concept is highlighted. Since the needed large bandwidth for highdata rates is a very valuable resource, future communications systems need a high spectrum flexibility. Furthermore, 4G systems will face severe inter-cell interference scenarios that have to be tackled. Both challenges, i.e., spectrum flexibility and inter-cellinterference, are discussed in more detail in this paper. At the end, a possible time line for the evolution of a next generation mobile communications system is given.
