 The PHY model is based on the well-known Gaussian interference models, according to which the powers of interfering signals (in linear units) are summed up together to determine the overall interference power.
 
-The sequence diagram of Figure :ref:`fig-phy` shows how interfering signals are processed to calculate the SINR, and how SINR is then used for the generation of CQI feedback.
