A method of supporting multiple code types in a wireless mobile communication system is disclosed. More specifically, a mobile station (MS) receives a channel descriptor from a base station (BS), wherein the channel descriptor includes at least one burst profile which includes a code type and an interval usage code. Thereafter, the MS, first, recognizes the code type which includes information on coding scheme to be used by the BS or the MS, and recognizes, second, an interval usage code which is used for classifying all data bursts.
