| 摘要 |
The present invention relates to a wireless communications system, and more particularly to a method for sensing a channel dynamically in a wireless LAN system and an apparatus therefor. A method for performing CCA (Clear Channel Assessment) by a station (STA) in a wireless LAN system according to an embodiment of the present invention includes the steps of: receiving by a physical layer (PHY) of the STA a request primitive including a parameter indicating a CCA level type from an upper layer, and determining whether a signal equal to or greater than a prescribed CCA threshold is sensed based on the value of the parameter. Here, the parameter may be set so as to indicate one of a plurality of different CCA level types. |
