Abstract

A method of wireless communication is presented. The method includes signaling a first number of channel state information reference signal (CSI RS) ports corresponding to resource elements (REs) and a second number of virtual antenna ports the second number being less than or equal to the first number. The method also includes transmitting CSI RS on each virtual antenna port the CSI RS mapped to at least a portion of the REs.
