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 5G resource grid?
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 and resource element?
A Resource Element is one 15 kHz subcarrier by one symbol. Resource Elements aggregate into Resource Blocks . A Resource Block has dimensions of subcarriers by symbols. Twelve consecutive subcarriers in the frequency domain and six or seven symbols in the time domain form each Resource Block.

A E-UTRA PRB (Physical Resource Block) is defined as consisting of 12 consecutive subcarriers for one slot (0.5 ms) . A PRB is the smallest element of resource allocation assigned by the eNB scheduler.
