Abstract
A scanning method in a wireless local area network (WLAN) system is provided. The scanning method includes transmitting, by a station, a probe request frame and receiving, by the station, a probe response frame from an access point (AP). The AP determines whether to transmit the probe response frame in response to the probe request frame using information indicated by the probe request frame.
Claims12
A scanning method of an access point (AP), in a wireless local area network (WLAN) system, the method comprising:
- receiving, by the AP, a probe request frame, and
- determining, by the AP, whether to transmit the probe response frame to the STA,
- wherein the probe response frame is not transmitted by the AP when the probe request frame includes information regarding a max channel time, and the AP is unable to satisfy the response time constraint specified in the max channel time,
- wherein the information regarding the max channel time includes information indicating a time that the station is available after transmission of the probe request frame to receive a probe response frame as responses with respect to the probe request frame in a channel.
An access point (AP) in a wireless local area network (WLAN) system, the AP comprising:
- a processor;
- and
- a transmitter,
- wherein the processor is configured to:
- receive a probe request frame, and
- determine whether to transmit the probe response frame to the STA,
- wherein the probe response frame is not transmitted by the AP when the probe request frame includes information regarding a max channel time, and the AP is unable to satisfy the response time constraint specified in the max channel time,
- wherein the information regarding the max channel time includes information indicating a time that the station is available after transmission of the probe request frame to receive a probe response frame as responses with respect to the probe request frame in a channel.
