Method and apparatus for a scanning in WLAN |
摘要 |
The methods and an apparatuses for scanning in WLAN are disclosed. A method of a scanning of a station (STA) may include monitoring a channel during a probedelay based on a MAC sublayer management entity (MLME)-SCAN.request primitive indicating an active scanning for a target Access Point (AP), receiving a frame including a channel congestion indicator from an AP during the probedelay, generating a MLME-SCAN.change request primitive to request a change of a scanning type parameter included in the MLME-SCAN.request primitive when the channel congestion indicator indicates that the channel is congested, generating a MLME-SCAN.change confirm primitive to confirm the change of the scanning type parameter included in the MLME-SCAN.request primitive as a response of the MLME-SCAN.change request primitive, and performing a passive scanning for the target AP based on the MLME-SCAN.change confirm primitive. |

1. A method of a scanning of a station (STA), the method comprising:
monitoring a channel during a probedelay based on a MAC sublayer management entity (MLME)-SCAN.request primitive indicating an active scanning for a target Access Point (AP); receiving a frame including a channel congestion indicator from an AP during the probedelay; generating a MLME-SCAN.change request primitive to request a change of a scanning type parameter included in the MLME-SCAN.request primitive when the channel congestion indicator indicates that the channel is congested; generating a MLME-SCAN.change confirm primitive to confirm the change of the scanning type parameter included in the MLME-SCAN.request primitive as a response of the MLME-SCAN.change request primitive; and performing a passive scanning for the target AP based on the MLME-SCAN.change confirm primitive. |
