Method and device for performing communication by using plurality of resource arrangement techniques in wireless lan system

A method and a device for performing communication by using various RUs in a wireless LAN are presented. If a center resource unit located in the vicinity of a DC frequency band exists, whether the corresponding center resource unit is used can be determined according to whether a discontinuous channel allocation is applied. The center resource unit can be used as a null subcarrier for canceling the interference, which becomes a problem due to the discontinuous channel allocation. If the center resource unit is used as the null subcarrier, the center resource unit is inserted into different frequency chunks, thereby mitigating the interference that can be generated for each frequency chunk.
