Claim of US Patent No. 11,032,846

1. A method of controlling channel access performed by an access point (AP) in a wireless local area network (WLAN) system, the method comprising:receiving, from a station (STA), a request frame comprising a bit value indicating whether to request protection of a resource for a target wake time (TWT) to the AP;
determining whether to protect the resource for the TWT based on the bit value of the request frame; and
transmitting, to the STA, a response frame comprising a bit value indicating whether the resource for the TWT is to be protected, in response to receiving the request for the protecting the resource,
wherein the bit value of the request frame is a first value when the STA requests the protection of the resource for the TWT and the bit value of the request frame is a second value when the STA does not request the protection of the resource for the TWT.
