In LTE, a Physical Resource Block (PRB) is defined as consisting of 12 consecutive subcarriers for one slot (0.5 ms), and is the smallest element of resource allocation assigned by the eNodeB scheduler.
But i also read it as Resource Block (RB), so I’m getting confused… What’s the tricky in here?
My query is: is RB and PRB exactly the same? (One RB = One PRB?). When to use RB and when to use PRB?
If below image is correct, then MPIRICAL definiton is wrong (https://www.mpirical.com/glossary/prb-physical-resource-block).
