Title:
METHOD AND DEVICE FOR TRANSMITTING DATA IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/055016
Kind Code:
A1
Abstract:
Provided are a method and device for transmitting data in a wireless LAN system. In particular, an AP performs first carrier sensing on a first band, and performs second carrier sensing on a second band. The AP transmits first data to an STA through a multi-band on the basis of results of the first and second carrier sensing. In the multi-band, the first band and the second band are combined. As the result of the first carrier sensing, when a channel of the first band is idle, first TXOP duration of the first band in which first data is transmitted is configured. As the result of the second carrier sensing, when a channel of the second band is busy, the second carrier sensing is performed again on the second band. As a result of the second carrier sensing performed a plurality of times, when the channel of the second band is idle, second TXOP duration of the second band in which the first data is transmitted is configured. A time point at which the second TXOP duration ends is set to be equal to a time point at which the first TXOP duration ends.
