Disclosed are a method and an apparatus for scanning in a wireless LAN. A method for scanning by a station (STA) can comprise the steps of: the STA unicasting a probe request frame to a target access point (AP) from a first channel, the target AP having been determined in accordance with a basic service identifier (BSSID) comprised in an MLME.SCAN.request.primitive; the STA processing an acknowledgment (ACK) transmitted via the first channel within a first ACK transmission time, and determining whether the first ACK for the probe request frame is received; if the first ACK is received within the first ACK transmission time, then the STA monitoring a probe response frame, which is a response to the probe request frame from the first channel; and if the first ACK is not received within the first ACK transmission time, then regardless of a clear channel assessment (CCA) level detected during the first ACK transmission time, the STA switching the scanning channel from the first channel to a second channel when a timer for the first ACK transmission time expires. |
