Claim of US Patent No. 10,602,510

1. A method of operating a first station (STA) in a wireless LAN (WLAN), the method comprising:receiving assignment information on one or more channels from an access point (AP) through a first primary channel; and
based on the first primary channel being not included in the one or more channels, receiving information indicating that a channel among the one or more channels is designated as a second primary channel from the AP,
wherein the first STA uses the second primary channel as a primary channel during a period to which the one or more channels are assigned,
wherein, in a case where the first STA receives a beacon frame indicating to use the first primary channel as a primary channel from the AP after data is transmitted to a second STA, the first STA uses the first primary channel as a primary channel instead of the second primary channel, and
wherein, in a case where data transmission transmitted to the second STA is completed, the first STA immediately uses the first primary channel as a primary channel instead of the second primary channel.
