Physical Resource Block (PRB) = 2*Resource Block = 12 Subcarriers x 14 OFDM in 1ms . RE can deliver 2, 4, 6, 8 bits in QPSK, 16QAM, 64QAM, 256QAM respectively. If we calculate for 64QAM as 6bits since 256QAM not widely spread (check Samsung S7 in T-Mobile). 20MHz ==> 100 PRB ==> 100*168*1000 = 16,800,000 RE in 1 s.

Resource Element(RE) : The smallest unit made up of 1 symbol x 1 subcarrier. RB (Resource Block) : I think everybody would know what this is. This is a unit of 84 resource elements which is 12 subcarrier by 7 symbols (This is with normal Cylic Prefix which is used in most of the LTE deployment.

5G NR retains the concept of 10 millisecond frame divided into 10 one-millisecond subframes.
Read moreWhat is the channel bandwidth of 5G?
In comparison, 5G NR maximum carrier bandwidth is up to 100 MHz in frequency range 1 (FR1: 450 MHz to 6 GHz), or up to 400 MHz in frequency range 2 (FR2: 24.25 GHz to 52.6 GHz) that can be aggregated with a maximum bandwidth of 800 MHz.
Read moreWhat is OFDM numerology?
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.
Read moreWhat 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.
Read moreHow do you find the number of subcarriers in 5G?
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.
