Channel aggregation is performed to communicate using a plurality of aggregated channels including a primary channel and at least one non-primary channel. Performing CSMA to gain access to the primary channel, determining a channel status of the primary channel, and performing sensing on at least one non-primary channel if the channel status is not busy, Is busy, the channel status of at least one non-primary channel is assumed to be busy. Accordingly, the channel status of the non-primary channel is determined based on the channel status of the primary channel and sensing on at least one non-primary channel, and either the primary channel or the non-primary channel determined to be usable is used. Perform aggregated transmission. [Selection] Figure 3 |
