How do you find the number of subcarriers in 5G?

OFDM numerology design for wide range of carrier frequencies, deployment types, and application latency requirements using regular slots . 100 GHz. Frequency. 15 kHz. 30 kHz.

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.

Number of subcarrier per PRB is 12 . Number of OFDM symbols per slot may vary depending on subcarrier spacing. For subcarrier spacing <= 60, the number of OFDM symbols / slot = 7 or 14. For subcarrier spacing > 60, the number of OFDM symbols / slot = 14.

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.

Each slot typically consists of 14 OFDM symbols .

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.

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
