METHOD AND DEVICE FOR CONTROLLING CHANNEL ACCESS IN WIRELESS LAN SYSTEM
First Claim
1. A method of controlling channel access at a station (STA) of a wireless communication system, the method comprising:
- transmitting a first frame for initiating a transmission opportunity (TXOP) to an access point (AP); and
receiving a second frame, in response to the first frame from the AP,wherein the second frame includes information indicating a channel access allowance time of the STA.

Abstract
The present invention relates to a wireless communication system, and more specifically, provides a method and a device for controlling channel access in a wireless LAN system. A method for controlling channel access by a station (STA) in a wireless communication system according to one embodiment of the present invention comprises the steps of: transmitting a first frame, to an access point (AP), for starting a transmission opportunity (TXOP); and receiving a second frame if the second frame responding to the first frame is transmitted from the AP, wherein the second frame can be transmitted from the AP on the basis of whether a duration of the TXOP overlaps a predetermined time set by the AP.

14. A station (STA) apparatus for controlling channel access in a wireless communication system, the STA apparatus comprising:
-
a transceiver; and a processor, wherein the processor is configured to transmit a first frame for initiating a transmission opportunity (TXOP) to an access point (AP) using the transceiver and to receive a second frame in response to the first frame from the AP using the transceiver, and wherein the second frame includes information indicating a channel access allowance time of the STA.
