In this paper, we study the degrees of freedom (DOF) for three-user multiple-input and multiple-output (MIMO) Y channel, where each user equipment (UE) sends two independent messages to the other two UEs while receiving two independent messages from them via a common relay node. We assume each UE is equipped with AI antennas and is semi-blind in the sense that no channel state information at the transmitter (CSIT) is available in multiple access (MAC) phase, while the relay is equipped with AT
