Dynamic spectrum sharing (DSS) has been introduced to enable 5G New Radio (NR) and LTE to share the same frequency range 1 (FR1) spectrum bands. Providing a coverage layer at lower frequencies, DSS allows network operators to transition smoothly from 4G LTE to 5G NR standalone (SA) mode. In the network, DSS only requires to enable MBSFN subframes, an LTE Release 9 feature, for the transmission of 5G NR synchronization signal blocks (SSB) and tracking reference signals (TRS). This video explores testing of an LTE-capable device in presence of 5G NR SSB’s while enabling MBSFN subframes.

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