Provided is a method for providing information related to at least one channel supported in a wireless local area network (WLAN) system. For example, an extreme high throughput (EHT) operation element may include information related to at least one channel in a first band supporting an EHT standard. A very high throughput (VHT) operation element may include information related to at least one channel in a second band supporting a VHT standard. A high throughput (HT) operation element may include information related to at least one channel in a third band supporting an HT standard. The EHT operation element may include information for a channel number related to at least one channel in the first band and information related to a primary channel in the first band.
