Control channel element 38.211

A control-channel element consists (CCE) of 6 resource-element groups (REGs)
A resource-element group (REG) equals one resource block during one OFDM symbol (1 REG = 12 RE)
For 273 PRBs, there is maximum 273/6 = 45 CCEs, or 45*6 = 270 REGs, on 1 symbol

Maximum CCE / symbol below 6 GHz
