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 .
Read moreWhy 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

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.
Read moreWhat is a resource grid?
– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . … – There are a set of resource grids per transmission direction (uplink or downlink).
Read moreWhat is resource element in 5G NR?
In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE . In LTE resource block bandwidth is fixed to 180 KHz but in NR it is not fixed and depend on sub-carrier spacing.24 Nis 2019

PRB refer to block assigned to user by scheduler . In 5G we have VRB to PRB mapping which depends on Downlink resource allocation type, it can be interleaved or non inter leaved.
