The sum constraint in applies because the two users send inde- pendent information and cannot cooperate in the encoding. If they could cooperate, what is the maximum sum rate they could achieve, still assuming individual power constraints P1 and P2 on the two users? In the case P1 = P2, quantify the cooperation gain at low and at high SNR. In which regime is the gain more significant?
