What is LTE numerology?

Numerology corresponds to one subcarrier spacing in the frequency domain . NR supports a flexible numerology with a range of subcarrier spacings, based on scaling a baseline subcarrier spacing of 15 kHz. By scaling a reference subcarrier spacing by an integer N, different numerologies can be defined.

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 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.

What is RRC setup in 5G?

The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station . This protocol is specified by 3GPP in TS 25.331 for UMTS, in TS 36.331 for LTE and in TS 38.331 for 5G New Radio.

What is RRC message?

The RRC messages are encrypted and checked for integrity . The RRC ConnectionReconfiguration message is used by the eNB entity to command a modification of the RRC connection. This message may relate to the configuration of the measurements, control of the mobility and configuration of the DRB default bearer.

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
