Abstract: For a $K$-user interference channel with $M$ antenna at each transmitter andeach receiver, the maximum total DoF of this channel has been previouslydetermined to be $\max \sum {k=1}^K d k = MK-2$. However, the DoF regionremains to be unknown. In this short note, through a simple time-sharingargument, we obtain the degrees of freedom DoF region of this channel.
