    Abstract: A method for transmitting a multiple input multiple output (MIMO) packet in a wireless local area network is described. The method includes generating a physical layer protocol data unit (PPDU) including a short training field (STF), a long training field (LTF), a very high throughput (VHT)-signal field, a VHT-STF, a VHT-LTF and a plurality of data streams. The STF is used for at least one receiver to estimate an automatic gain control and a coarse frequency offset. The LTF is used for the at least one receiver to estimate a fine frequency offset. The VHT-STF is used for improving automatic gain control estimation in a MIMO transmission. The VHT-LTF is used for estimating a MIMO channel based on the plurality of data streams. The PPDU is transmitted to the at least one receiver.

    Abstract: The present invention relates to a wireless communication system. More particularly, a method and a device for restricted access window-based channel access in a WLAN system are disclosed. The method whereby a station (STA) performs channel access in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving restricted access window (RAW) cross-border transmission allowance (CBTA) information from an access point (AP) in case an RAW is allocated to the STA; and performing transmission by the STA on the basis of the RAW CBTA information. In case the RAW CBTA information is configured as a first value, transmission by the STA beyond the border of the RAW may be allowed.
