<p>A method and a device for performing active scanning are disclosed. The method for active scanning of a STA comprises the steps of: enabling the STA to transmit, to an AP, a probe request frame that contains channel monitoring type information in a scanning channel; enabling the STA to determine whether the scanning channel is in a busy state until a minimum channel time; enabling the STA to determine whether a PPDU including a valid PLCP header is received in the scanning channel until the minimum channel time; and enabling the STA to determine a time for monitoring a probe response frame transmitted by the AP in the scanning channel on the basis of whether the PPDU is received until the minimum channel time and of channel monitoring type information, when the scanning channel is in the busy state, wherein the channel monitoring type information can contain information on a type with which the STA monitors the probe response frame in the scanning channel.</p> |
