INCREASING CSI-RS OVERHEAD VIA ANTENNA PORT AUGMENTATION

摘要

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.
