Abstract: Proposed is a method for receiving a Wi-Fi service by a wireless LAN station supporting an application service platform (ASP). Specifically, the Wi-Fi service can be received through at least two connection techniques, for example, a Wi-Fi direct connection of Wi-Fi infrastructure connection may be used. The wireless LAN station having an ASP may detect information on each of the connection techniques and may be provided with the Wi-Fi service using one of the connection techniques. In addition, when a change in a communication environment or the like occurs, the connection technique may be switched and, in this case, signaling for switching the connection technique may be used.

Abstract: A wireless communication system is disclosed. Specifically, a channelization method in a whitespace band and an apparatus for the same are disclosed. A method for providing whitespace operation information includes transmitting, by a first station (STA) to a second STA, a frame including a TV whitespace high throughput (TVHT) operation information field. The TVHT operation information field includes primary channel number, channel width, channel center frequency segment 0 and channel center frequency segment 1 subfields. A channel center frequency of frequency segment 0 or frequency segment 1 is determined based on a channel start frequency. The channel start frequency is determined as a function of a TV channel index corresponding to the frequency segment 0 or a TV channel index corresponding to the frequency segment 1.
