Abstract
A method of frequency resource allocation for Channel State Information Reference Signal (CSI-RS) in a wireless communication system includes transmitting, from a base station (BS) to a user equipment (UE), a CSI-RS using a CSI-RS resource, calculating, with the UE, CSI based on the CSI-RS, and reporting, from the UE to the BS, the CSI. The CSI-RS resource in a frequency domain is allocated to one or more frequency resources that are part of a carrier bandwidth. The method further includes notifying, with the BS, the UE of a location of the one or more frequency resources in the frequency domain.
