A system and method for communicating channel state information reference signal (CSI-RS) in a communication network. A cell such as an eNodeB (eNB) or a transmit-receive-point (TRP) may transmit to a user equipment (UE) one or more synchronization signal (SS) blocks according to one or more beam directions available to the cell. Each beam direction may correspond to one or more antenna ports, and each SS block may correspond to an SS index. The cell may then transmit a CSI-RS signal configured according to the one or more antenna ports and the one or more SS blocks. In a different embodiment, the cell may select antenna ports of a neighbor cell for the CSI-RS signal based on a channel state measurement report of the neighbor cell received from the UE.
