1. A wireless communication method comprising:
storing a first Modulation and Coding Scheme (MCS) table supporting up to 64 Quadrature Amplitude Modulation (QAM) and a second MCS table supporting up to 256 QAM, and a third MCS table supporting up to 256 QAM, the third MCS table including a same number of MCS indices as the second MCS table and including less MCS indices corresponding to 256 QAM than the second MCS table;
receiving, through a wireless channel, table indication information indicating one of the first to third MCS tables; and
identifying one of the first to third MCS tables at a signal-to-noise ratio (SNR) according to the received table indication information to recognize a demodulation scheme for data to be received through the wireless channel,
wherein the receiving table indication information comprises receiving a high layer signal including the table indication information, and
wherein the table indication information is determined by detecting respective maximum throughputs with respect to MCS indices of the second MCS table and with respect to MCS indices of the third MCS table when the second and third MCS tables are available,
the table indication information comprises a Control Format Indicator (CFI) received through a Physical Control Format Indicator Channel (PCFICH), and
the identifying one of the first to third MCS tables includes identifying the third MCS table in response to the CFI being equal to 3.
