The answer is at the end of this article. 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).

– 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).

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
Read moreWhat is PRB in 5G NR?
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.
Read moreWhat is VRB PRB mapping 5G?
An RBG is a set of consecutive Virtual Resource Blocks (VRB). In type 0, non-interleaved VRB-to-PRB mapping is performed, meaning that VRB n is directly mapped to PRB n. The number of RBs within an RBG are derived based on the RRC parameter rbg-size configured by PDSCH-Config and the size of the bandwidth part.
Read moreHow are resource blocks allocated in LTE?
In LTE, radio resources are divided into time and frequency resource elements. Resource elements in time axis are divided into number of OFDM symbols and in frequency axis are divided into number of sub-carriers . Resource element (RE) is a smallest resource unit, which occupies a single sub-carrier and an OFDM symbol.
Read moreHow are resource blocks calculated?
For 50 Mbls one has to assign x blocks= (50/100.8)x total no. of resource blocks(100)= one has to assign 50 resource blocks, and in case of 60 Mbls the number of assigned RBs= (60/100.8) 100=60. In one second the transmitted bits will be 50Mbits and 60 Mbits respectively.
