Abstract: A method and a user equipment (UE) are described for decoding data in a wireless access system. A higher layer signal is received that includes an indication that 256 quadrature amplitude modulation (256QAM) is to be enabled. In one embodiment, downlink control information (DCI) is received via a physical downlink control channel (PDCCH) for scheduling a physical downlink shared channel (PDSCH). Data is received via the PDSCH. The received data is decoded using one of two modulation and coding scheme (MCS) index tables. 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 256QAM. The received data is decoded based on only the first MCS index table even though the 256QAM has been enabled, when a format of the DCI is a DCI format 1A.
