N2 - The capacity bounds are studied for the multipleantenna real full-duplex Gaussian relay channel with t1 transmitting antennas at the sender, r2 receiving and t2 transmitting antennas at the relay, and r3 receiving antennas at the receiver. It is shown that compress-forward and partial decode-forward achieve within (1/2)(min(t 1 + t2, r3) + r2) bits and (1/2) min(t1, r2) bits, respectively, from the cutset bound. Unlike the single-antenna case, partial decode-forward can be arbitrarily better than optimal selection between decode-forward and direct transmission. Similar gap results for half-duplex models are briefly discussed.
