dynamic spectrum sharing (5G) (DSS)

Dynamic Spectrum Sharing(DSS) is a method of using frequency ranges more efficiently. The DSS method was published in 5G Release 15 of Long Term Evolution Advanced( LTE-A) and is used for the simultaneous spectrum use of Long Term Evolution (LTE) and 5th generation mobile networks (5G).

Long Term Evolution (LTE) is a 4th generation( 4G) mobile network and, like the 5G mobile network, uses digital dividendfrequencies in the 700 MHz frequency range to cover sparsely populated areas. Since 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. With this technique, the transmitter infrastructure is not blocked by one mobile technology, but is made available to one or the other as needed, depending on demand. This results in greater spectrum economy.

DSS technology 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.
