METHOD FOR TRANSMITTING AND RECEIVING BROADCASTING CHANNELS

摘要

The present invention relates to a wireless access system and discloses various superframe structures and superframe header structures, and a method for transmitting and receiving broadcasting channels efficiently. In one embodiment of the present invention, the method for receiving broadcasting channels efficiently comprises the steps of: receiving from a mobile terminal a first broadcasting channel that includes first information on the modulation and coding scheme (MCS) applied to a second broadcasting channel; and receiving from the mobile terminal the second broadcasting channel by using the first information. At this time, the first broadcasting channel can be transmitted using a fixed-rate MCS, and the second broadcasting channel can be transmitted using a variable-rate MCS.
