发明名称 Frequenzbandvergabe an Funk-Kommunikationssysteme
摘要 According to the invention, at least two radiocommunication systems overlap spatially and the radio interface in a radiocommunication system comprises at least a first and a second frequency band. Instead of allocating several frequency bands block by block to a radiocommunication system, at least one frequency band of another radiocommunication system is arranged between the frequencies of the first and second frequency band, whereby a minimum distance is created between the frequency bands used in a location. In a UMTS, an FDD-mode frequency band can also be used in a TDD mode in an uplink and assymmetrical data services can be provided with enhanced support.
