  Abstract: For the two-user multiple-input multiple-output (MIMO) broadcast channel with delayed channel state information at transmitter (CSIT) and arbitrary antenna configurations, all the degrees-of-freedom (DoF) regions were obtained. However, for the three-user MIMO broadcast channel with delayed CSIT and arbitrary antenna configurations, the DoF region of order-2 messages is still unclear and only a partial achievable DoF region of order-1 messages was obtained. In this paper, for the three-user MIMO broadcast channel with delayed CSIT and arbitrary antenna configurations, we first design the achievable scheme for each antenna configuration case, and then introduce a structuring method for analyzing the inherent achievable DoF region of the proposed scheme. As a result, the DoF region of order-2 messages is precisely characterized and an achievable DoF region of order-1 messages is completely expressed.
