METHOD AND DEVICE FOR RESTRICTED ACCESS WINDOW-BASED CHANNEL ACCESS IN WLAN SYSTEM
First Claim
1. A method for performing channel access by a station (STA) in a wireless communication system, the method comprising:
- receiving restricted access window (RAW) cross boundary transmission allowance (CBTA) information from an access point (AP) when a RAW is allocated to the STA; and
performing transmission from the STA based on the RAW CBTA information,wherein, when the RAW CBTA information is set to a first value, transmission of the STA extended across a boundary of the RAW is permitted.

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.

12. A method for supporting channel access of a station (STA) by an access point (AP) in a wireless communication system, the method comprising:
-
transmitting restricted access window (RAW) cross boundary transmission allowance (CBTA) information to the STA when a RAW is allocated to the STA; and performing transmission from the STA based on the RAW CBTA information, wherein, when the RAW CBTA information is set to a first value, transmission of the STA extended across a boundary of the RAW is permitted.

13. A station (STA) for performing channel access in a wireless communication system, the STA comprising:
-
a transceiver; and a processor, wherein the processor is configured to receive restricted access window (RAW) cross boundary transmission allowance (CBTA) information from an access point (AP) using the transceiver when a RAW is allocated to the STA; and
perform transmission from the STA using the transceiver based on the RAW CBTA information, andwherein, when the RAW CBTA information is set to a first value, transmission of the STA extended across a boundary of the RAW is permitted.
