What is a numerology in 5G?

5G Numerology? ©3G4G In the context of 3GPP 5G standardization contributions, the term numerology refers to the configuration of waveform parameters , and different numerologies are considered as OFDM-based sub-frames having different parameters such as subcarrier spacing/symbol time, CP size, etc.

Why is 5G different in numerology?

Different numerologies can be transmitted on the same carrier frequency with a new feature called bandwidth parts . These can be multiplexed in the frequency domain. Mixing different numerologies on a carrier can cause interference with subcarriers of another numerology.7 Eyl 2018

What is RRC IDLE state in 5G?

In 5G, they have introduced new RRC Stats called “RRC Inactive” to minimize latency as well as to reduce signalling load . Transitions from RRC Inactive to Connected is very quick as UE Context is stored at gNB and UE. NG signalling keep alive between gNB to AMF, GTP-U also remain alive between gNB to UPF.1 Tem 2020

What are RRC states?

There are three RRC states; RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED are defined for a 5G NR UE. While RRC_IDLE and RRC_CONNECTED states in NR are almost same as those of LTE, the RRC_INACTIVE states is newly introduced in 5G NR.
