Claim Text:
1. A method for decoding data in a wireless access system, the method performed by a user equipment (UE) and comprising: receiving a higher layer signal including an indication that 256 quadrature amplitude modulation (256QAM) is to be enabled; receiving, via a physical downlink control channel (PDCCH), downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH); receiving, via the PDSCH, data; and decoding the received data using one of two modulation and coding scheme (MCS) index tables, wherein the UE has a first MCS index table supporting up to 64 quadrature amplitude modulation (64QAM) and a second MCS index table supporting up to the 256QAM, and wherein the received data is decoded based on the first MCS index table even though the second MCS index table has been enabled to the UE, when a format of the DCI is a DCI format 1A.
