description An adaptive modulation and coding (AMC) method and apparatus for increasing up-link performance and a record medium storing the method are disclosed. In one embodiment, the method comprises: (a) receiving a signal from the base station, which stores an identical mapping table to that stored in the terminal, wherein the mapping table lists i) adaptive modulating and coding methods corresponding to plural signal-to-noise ratios (SNRs), and ii) mapping identifiers corresponding to the adaptive modulating and coding methods, (b) measuring a SNR for the received signal, (c) extracting a mapping identifier corresponding to the SNR, and (d) transmitting the mapping identifier to the base station so that the base station can demodulate and decode data received from the terminal by referring to the transmitted mapping identifier and the stored mapping table.
