Abstract:
1. A method for transmitting a channel state information reference signal (CSI-RS) comprising: identifying a location of one or more subframes where one or more CSI-RS reuse patterns are transmitted; identifying a location of one or more resource elements (REs) used to transmit a CSI-RS within a CSI-RS subframe wherein the REs that comprise a CSI-RS reuse pattern are specified by the number of CSI-RS ports and the location of a first resource element (RE # providing a location of the one or more subframes and one or more REs where the one or more CSI-RS reuse patterns are transmitted to one or more pieces of user equipment (UE); and generating one or more CSI-RS modulation symbols in one or more CSI-RS REs, respectively, where each symbol contains a CSI-RS sequence element as a multiplication component.
