Abstract
A method for reporting, by a UE, a downlink channel state in a wireless communication system according to an embodiment of the present invention includes: receiving a vertical precoding matrix indicator (PMI) to be used to calculate the downlink channel state; calculating a value of the downlink channel state using the received vertical PMI; and reporting the calculated downlink channel state value to an eNB, wherein the received vertical PMI is used from a later subframe between a subframe in which the vertical PMI is received and a subframe preceding a subframe in which the calculated downlink channel state value is reported by the number of subframes necessary to calculate the downlink channel state value using the received vertical PMI.
