Abstract: In this paper, the role of cooperation in managing interference-a fundamental feature of the wireless channel-is investigated by studying the two-user Gaussian interference channel where the source nodes can both transmit and receive in full duplex. The sum capacity of this channel is obtained within a gap of a constant number of bits. The coding scheme used builds up on the superposition scheme of Han and Kobayashi for the two-user interference channel without cooperation. New upperbounds on the sum capacity are also derived. The same coding scheme is shown to obtain the sum capacity of the symmetric two-user Gaussian interference channel with noiseless feedback within a constant gap.
