can any one please help me to find out what is the difference between the LTE OFDMA PRBs and LTE phsical layer frame?
i'm confused when i read that PRB consist of 12 sub-carriers and each PRB equal a time slot (0.5 msec) , but in the lte frame each time slot contain 7 ofdm symbols does it mean that 12 sub-carriers will carry 7 ofdm symbols ???!!!!!
 

From this reference: lte_downlink_generic_frame_mimo
Frame Duration = 10 ms or 10/1000000 second.
One Frame has 10 sub-frames.
Sub-frame duration = 1 ms or 1/1000000 second.
One Sub-frame has 2 time slots.
One Time slot = .5 ms or 1/2000000 second.
Each Time slot contains 7 OFDM symbols with normal Cyclic Prefix.
