Demystifying 5G – 5G NR coexistence with LTE based on dynamic spectrum sharing (DSS)

5G New Radio (NR) supports the frequency range 1 (FR1) from 410 MHz to 7.125 GHz that is already intensively utilized by 4G LTE – in particular those frequency bands organized as paired spectrum (FDD). Traditionally, selected frequency bands would be cleared from LTE to be deployed by 5G NR. To avoid the high costs associated with this option, 5G NR added dynamic spectrum sharing (DSS) that enables to share the same frequency band with LTE. The video explores the technological fundamentals that enables DSS between 5G NR and LTE.

The demystifying 5G video series discusses main topics related to 5G including new technology components, procedures and testing challenges.
