dynamic spectrum sharing (DSS)

Dynamic Spectrum Sharing (DSS) is a procedure with which frequency ranges can be used more efficiently. The DSS procedure was published in Release 15 of Long Term Evolution Advanced (LTE-A) and is used for the simultaneous frequency use of Long Term Evolution (LTE) and 5th generationmobile networks

(5G). Long Term Evolution (LTE) is a 4th generation (4G) mobile network and, like the 5G mobile network, uses Digital Dividendfrequencies

inthe 700 MHz

frequencyrange to cover sparsely populated areas. As radio masts for Long Term Evolution (LTE) are already in place in large parts of Germany, Dynamic Spectrum Sharing has been developed as an economical technique that uses the existing LTE transmitter infrastructure for 5G transmissions. In this technique, the transmitter infrastructure is not blocked by one mobile technology, but is made available to one technology or the other as needed, depending on demand. This results in greater spectrum economics

The DSS technique takes advantage of the fact that both Long Term Evolution (LTE) and 5G use Orthogonal Frequency Division Multiplex (OFDM). Both techniques can be seamlessly merged and channel resources can be dynamically shared between 4G users and 5G users.
