摘要：
A system and method for broadcasting a channel state information reference signal (CSI-RS) is disclosed. A CSI-RS that is orthogonal to CSI-RSs transmitted by each of a first network cell and each of a set of neighbor cells that interfere with the first network cell is identified. In one implementation, the first network cell has a coverage containing a coverage of a second network cell. The method includes transmitting, from the second network cell, the CSI-RS that is orthogonal to CSI-RSs transmitted by each of the first network cell and each of a set of interfering neighbor cells.
