    Abstract: 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.

    Abstract: The present invention relates to a method and terminal for detecting a physical hybrid-ARQ indicator channel (PHICH) in a wireless access system that supports enhanced inter-cell interference coordination. In particular, the method includes: determining whether the PHICH exists in only a 0th orthogonal frequency division multiplexing (OFDM) symbol if a subframe transmitted by a neighboring base station is an almost blanked subframe (ABS); determining whether a common reference signal (CRS) of the neighboring base station collides with a CRS of a serving base station if the PHICH exists outside of the 0th OFDM symbol; determining whether CRS power of the neighboring base station does not collide with the CRS of the serving base station; and determining whether an acknowledgement/negative-acknowledgement (ACK/Negative-ACK) is detected by replacing a symbol of the PHICH, overlapped with the CRS power of the neighboring base station is greater than the preset threshold.
