The solar coronal rotation was studied based on the analysis of daily data variations of the solar activity index - the solar radiation flux at a wavelength of 10.7 cm - for six consecutive eleven-year solar cycles (from the 19th to the 24th). Using the calculated time diagrams of the change in the values of the revealed quasi-periods in the time structure of the radio index of each cycle, it was concluded that the corona at different stages of the eleven-year solar cycle can exhibit properties of both differential and "solid-body" rotation. Keywords: solar activity, photosphere, corona, radio emission, rotation.
