METHOD AND APPARATUS FOR SCANNING IN WIRELESS LAN

摘要

A method and an apparatus for scanning in a wireless LAN are disclosed. The method for scanning in a wireless LAN comprises the steps of: enabling a station (STA) to receive, from a first access point (AP) operated in a first channel, a detection frame comprising identifier information of a second AP operated in a second channel and beacon frame transmission time information of the second AP, and enabling the STA to scan a beacon frame of the second AP on the basis of the beacon frame transmission time information of the second AP. Thus, the present invention can rapidly perform a scanning operation.

主权项

1. A method for scanning in a wireless local area network (LAN), the method comprising:
receiving, by a station (STA), a discovery frame from a first access point (AP) operating on a first channel, the discovery frame including identifier information of a second AP operating on a second channel and beacon frame transmission time information of the second AP; and scanning, by the STA, a beacon frame of the second AP based on the beacon frame transmission time information of the second AP, wherein the beacon frame transmission time information of the second AP includes information on a difference between a transmission time of the discovery frame and a transmission time of a beacon frame of the second AP transmitted after the discovery frame is transmitted, and wherein a transmission period of the discovery frame is shorter than a transmission period of a beacon frame of the first AP.
