Abstract

The present invention relates to a method for allowing a station (STA) operable in a plurality of frequency bands to perform a fast session transfer (FST) to a white space band in a wireless local area network (WLAN), and a station device therefore. When an FST is performed, if a band to which mobility is desired through the FST is a white space band, a multi-band element transmitted in an FST request message is suggested to additionally include particular white space information for available channel information acquisition, which is not used by a licensed user in the white space band. Said particular white space information may contain information that indicates whether a target channel is an available channel, and/or performance (apparatus type) in a white space band of a station that requests an FST.

First claim

The invention claimed is:

1. A method for allowing a first station (STA) capable of being operated in a plurality of frequency bands to perform a fast session transfer (FST) to a whitespace band, the method comprising:
transmitting, by the first station (STA), a multi-band element including information used as an FST request message to specify a desired band to which the first STA will move through the FST, to a second station (STA);
if the desired band achieved through the FST…
