CHANNEL ESTIMATION METHOD AND APPARATUS USING REFERENCE SIGNAL |
摘要 |
The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for estimating a channel using a reference signal. According to one embodiment of the present invention, a method in which a terminal estimates a channel in a wireless communication system may comprise the steps of: receiving a cell-specific reference signal (CRS) and a channel state information-reference signal (CSI-RS) from a base station; generating CSI of a channel estimated using the CRS on the basis of a channel estimated using the CSI-RS and a mapping relationship between the CRS port and the CSI-RS port; reporting the generated CSI to the base station; and demodulating data on the basis of the channel estimated using the CRS. |
