1. A method for allocating submaps in a wireless access system, the method performed by a base station and comprising:
- configuring resource areas according to a size of the submap;
allocating a control header to the resource areas, the control header including subframe information, downlink submap allocation information, and uplink submap allocation information,wherein the subframe information includes resource unit (RU) distribution information which is selected from a first to a third scheme, the first scheme indicating a distribution ratio between distributed RUs and localized RUs, the second scheme indicating a bitmap of positions of distributed RUs, and the third scheme indicating an index of a predefined RU distribution;
allocating a downlink submap and an uplink submap to the resource areas based on the control header; and
transmitting the control header of the downlink submap and the uplink submap,wherein the downlink submap and the uplink submap are sequentially allocated to a first symbol column in the resource area configured by symbol columns and subchannel rows, and a remainder of the uplink submap is allocated to a first subchannel row when the whole of the uplink submap is not allocated to the first symbol column.

14. A method for receiving control channel information in a wireless access system, the method performed by a mobile station and comprising:
-
receiving a control header allocated to resource areas of a subframe, the control header including subframe information, downlink submap allocation information, and uplink submap allocation information, wherein the subframe information includes resource unit (RU) distribution information which is selected from a first to a third scheme, the first scheme indicating distribution ratio between distributed RUs and localized RUs, the second scheme indicating a bitmap of positions of distributed RUs, and the third scheme indicating an index of a predefined RU distribution; receiving a downlink submap and an uplink submap according to the control header; and transceiving data through the downlink channel and the uplink channel, wherein the downlink submap and the uplink submap are sequentially allocated to a first symbol column in the resource area configured by symbol columns and subchannel rows, and a remainder of the uplink submap is allocated to a first subchannel row when the whole of the uplink submap is not allocated to the first symbol column.
