If we choose. Ai,⌧,` =¯Ci,⌘⌧,⌘`+2. , then super Gaussian MIMO MAC and BC have same nofeedback capacity. (¯C: mirror image of C along counter-diagonal).

This work shows that for the multi-antenna Gaussian MAC and BC with perfect feedback, the largest achievable regions with linear-feedback schemes coincide ...

With our results we can thus determine the linear-feedback capacity region of the two-user Gaussian BC when either transmitter or receivers are single-antenna.
