Abstract: The present invention relates to a method performed by a station (STA) for transmitting and receiving signals in a wireless local area network (WLAN) system. More particularly, according to the present invention, when the STA performs signal transmission and reception through channel aggregation, the STA can transmit a signal by mapping spatial stream sequences of each spatial stream in individual channels based on a plurality of pieces of MCS information indicated by a transmitted and received header field or, on the contrary, by obtaining output bit values of a plurality of encoders from spatial stream sequences received through spatial streams in the individual channels. That is, the present invention is directed to a method for transmitting and receiving signals in the above-described manner and device for the same.

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.
