Abstract
A scanning method and apparatus in wireless LAN is disclosed. The method comprises determining, by an access point (AP), whether to accommodate a station (STA) conducting an initial link setup and transmitting, by the AP, a frame to the STA, the frame including scanning redirection information for the STA to switch other channel, other band, or a neighbor AP when the AP determines not to accommodate the STA. The scanning redirection information includes a band field and a channel field. The band field indicating a band in which the STA conducts the initial link setup when the STA conducts the initial link setup from current band to the other band. The channel field indicating a channel in which the STA conducts the initial link setup when the STA conducts the initial link setup from current channel to the other channel.
