摘要
The present invention provides hierarchical modulation methods for robust symbol transmission and reception in a wireless access system, and devices supporting same. A method for transmitting a hierarchically modulated (HM) symbol in a wireless access system, according to an embodiment of the present invention, comprises the steps of: generating a first symbol; generating a second symbol; generating an HM symbol by combining the first symbol and the second symbol; and transmitting the HM symbol, wherein the first symbol can be generated by means of a spatial multiplexing (SM) technique, a beam-forming technique, or a space-time coding technique and the second symbol can be generated by means of a spatial multiplexing (SM) technique, a beam-forming technique, or a space-time coding technique.
