5G Dynamic Spectrum Sharing Technologies, Testing and Verifications
5G New Radio (NR) is an exciting and fast-evolving mobile communication system, but 4G is still playing an important role in mobile network infrastructures. Already included in 3GPP Rel-15 and further enhanced in Rel-16, Dynamic Spectrum Sharing (DSS) is a powerful cost-effective, and efficient solution that has become a key part of mobile operators’ 5G strategy.
In this presentation, we will discuss DSS technology which smooths the migration path from 4G to 5G and enables coexistence between LTE and NR in the same radio channel, as well as required extensive testing and verifications for DSS implementation.
3GPP gNB Conformance Testing Overview, Challenges, New gNB Test Solutions
5G NR is being deployed around the world and promises to bring enhanced mobile broadband, ultra-reliable, low-latency communications, and massive machine-type communications.
These benefits are being realised through new technologies including a flexible physical layer interface, a new core network, and the use of new mmWave spectrum. This requires a new set of 3GPP NR gNB conformance tests to ensure base stations can deliver on the 5G NR promises.
