Patent Images
1. A scanning method performed by a STA (station) in a wireless LAN system, the method comprising:
- generating a probe request frame that includes a probe response option information element indicating whether SSID (service set ID) information or compressed SSID information is included in a short probe response frame,transmitting the probe request frame to an AP (access point); and
receiving the short probe response frame from the AP in response to the probe request frame including the probe response option information element,wherein the probe response option information element includes at least one probe response option bitmap field, andwherein each bit of each probe response option bitmap indicates whether a request is made to include corresponding option information.

13. A STA (station) for scanning in a wireless LAN system, the STA comprising:
-
a receiver; a transmitter; a processor configured to control the receiver and the transmitter, wherein the processor is further configured to; generate a probe request frame that includes a probe response option information element indicating whether SSID (service set ID) information or compressed SSID information is included in a short probe response frame, control the transmitter to transmit the probe request frame to an AP (access point), and control the receiver to receive the short probe response frame from the AP in response to the probe request frame including the probe response option information element, wherein the probe response option information element includes at least one probe response option bitmap field, and wherein each bit of each probe response option bitmap indicates whether a request is made to include corresponding option information. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
