What is a symbol in 5G?

If your phone has a 5G modem, you will see one of two symbols: 5G or 5G+. 5G means your phone is currently connected to 5G NR on a sub-6 GHz frequency . Bands in this range provide better coverage but slower speeds. The higher the frequency, the faster your download speeds.

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 synchronization in 5G?

Uplink Synchronization : This is the process in which UE figure out the exact timing when it should send uplink data (i.e, PUSCH / PUCCH). Usually a network (gNB) is handling multiple UEs and the network has to ensure that the uplink signal from every UE should be aligned with a common receiver timer of the network.

What is PSS and SSS in 5G?

PSS stands for Primary Synchronization Signal, SSS stands for Secondary Synchronization Signal and ESS stands for Extended Synchronization Signal. Radio frame in 5G-TF is 10ms in duration. It has total 100 slots or 50 subframes. Each subframe consists of two consecutive slots.

What is synchronization signal?

Transmission of a synchronizing signal along with the message signal is an approach in which the transmitter simultaneously sends a clock pilot at a multiple of symbol rate along with the information data, and the receiver then employs a very narrow BPF tuned to the clock frequency.
