There is no difference in RB and PRB , RB is just a virtual imagination for MAC to schedule. Actual resource is PRB. If MAC scheduled 10 RB then PHY will map this to 10 PRB. It can be one to one mapping or different based on the RAT used in MAC.
in one time slots (1 ms )100 RB will be there in 20Mhz BW ENB (MAC point of view). Actual resource is 200 RB's in one time slot (one sub frame) in PHY point of view.
