Abstract: A method for receiving a signal by a station in a wireless LAN system, according to an embodiment of the present invention, comprises the steps of: receiving one of a plurality of per channel SIG-Bs, comprised in a SIG-B field, via a first channel among the transmission bandwidth of a multi-user (MU) frame comprising SIG-B field and data; and receiving the data of the MU frame on a second channel differing from the first channel via which the per channel SIG-Bs have been received. Although any one of the plurality of per channel SIG-Bs is transmitted on the second channel, the data of the MU frame is received by means of the per channel SIG-Bs that are transmitted on the first channel instead of the per channel SIG-Bs that are transmitted on the second channel.

Abstract: The present specification relates to a method for transmitting, by a station (STA), data through channel bonding in a wireless LAN (WLAN) system, and an apparatus therefor. The station therefor receives scheduling information from an access point (AP), wherein the scheduling information includes information on a channel-bonding beacon interval and information on a non-channel-bonding beacon interval. If the station has channel-bonding capability and data to be transmitted through channel bonding, the station can transmit the data on the basis of the channel bonding through the channel-bonding beacon interval.

Abstract: The present invention relates to a wireless access system supporting millimeter waves (mmWave) and provides methods for performing fast fallback so as to avoid link disconnections and devices for supporting same. The method whereby a legacy base station supports the fast fallback of a mmWave terminal in a wireless access system supporting millimeter waves (mmWave), according to one embodiment of the present invention, may comprise the steps of: receiving, from the mmWave terminal, a first fallback request message for requesting fast fallback; operating a fallback timer for determining whether or not to perform fallback after receiving the first fallback request message; and determining whether or not a second fallback request message for requesting fast fallback has been received from a mmWave base station within the fallback timer.
