Abstract: The present document relates to a method for efficiently performing uplink multi-user transmission in a wireless LAN system and an apparatus therefor. To this end, an access point (AP) may transmit a downlink multi-user frame to a plurality of STAs, receive an uplink frame including an acknowledgement/non-acknowledgement (ACK/NACK) signal for the downlink multi-user frame and an uplink scheduling request signal from at least two STAs among the STAs, transmit a downlink frame including uplink scheduling information to the at least two STAs on the basis of the uplink scheduling request signal, and receive an uplink multi-user frame including data from the at least two STAs in response thereto. Here, an SIG field of the downlink frame preferably comprises an indicator indicating that the downlink frame includes uplink multi-user scheduling information.

Abstract: Disclosed are a method and an apparatus for active scanning in a wireless LAN. In the method for active scanning in the wireless LAN, a scanning STA, which has received from a different STA a first probe request frame, can start a probe timer and perform a clear channel assessment (CCA) for detecting a channel state of a receiving channel. When the channel state is not busy until the probe timer reaches a minimum channel time, the scanning STA transmits to an AP from the receiving channel a second probe request frame, and when the channel state is busy until the probe timer reaches the minimum channel time and the scanning STA does not receive a probe reply frame, which includes at least the same information expected to be received based on scanning information, the scanning STA can transmit to the AP from the receiving channel the second probe request frame.

Abstract: The present invention relates to a broadband wireless access system, and more particularly, to a method of preventing a terminal from performing an unnecessary operation in a multicarrier environment, and a device for performing the method. An operating method of a terminal operating as a carrier aggregation mode in a broadband wireless access system supporting a multi carrier according to an embodiment of the present invention includes: obtaining system information on a neighbor base station and trigger function information applied to a carrier aggregation mode through a first broadcast message broadcasted from a serving base station; scanning a channel state for at least one carrier of a neighbor base station supporting a multicarrier by using the obtained system information; and transmitting a second message to the serving base station if the scanning result satisfies a condition based on the trigger function information.

Abstract: The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.
