What 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.

How 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.
