Disclosed in the present invention are a method for estimating a channel in a wireless access system in which a macro cell and a pico cell coexist, and an apparatus for same. More specifically, the present invention comprises the steps of: determining whether a cell-specific reference signal (CRS) that is inserted into a subframe of a pico cell, which corresponds to a multicast broadcast signal frequency network (MBSFN) almost blank subframe (ABS), overlaps with a CRS that is inserted into an MBSFN ABS of the macro cell, when the MBSFN ABS is transmitted from the macro cell; estimating the channel by using a CRS from the pico cell that remains after excluding the CRS that overlaps with the CRS of the macro cell; and decoding the channel which is received from the subframe of the pico cell by using a channel estimation value. |
