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.

It is the smallest unit of the resource grid made up of one subcarrier in frequency domain and one OFDM symbol in time domain. … There is one resource grid for a given antenna port p , subcarrier spacing configuration u, and transmission direction (downlink or uplink).

Read moreWhat is resource block allocation?
A resource block (RB) is a minimum resource allocation unit to any single user . One resource block occupies 12 sub-carriers and 6/7 OFDM symbols. Therefore, a resource block can have total 72/84 resource elements. The technology supports flexible bandwidths such as 1.4MHz, 3MHz, 5MHZ, 10MHz, 15MHz and 20MHz.
