AP (Access Point) station has a capability to acquire information for available channels from a database using a specific protocol related to an operation within the White Space (e.g. Access Network Query Protocol (ANQP)). And, non-AP station can retrieve the information for available channels by transmitting a Generic Advertisement Service (GAS) initial request frame to the AP station, wherein the GAS initial request frame comprises an Advertisement Protocol Element whose element ID indicates the specific protocol, and receiving a GAS initial response frame comprising a White Space Map (WSM) the specific protocol. The WSM comprises one or more white space channel units, and each of the white space channel units comprises a channel number field indicating one of the available channels and a power constraint field indicating a maximum allowable power on the indicated channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for acquiring available channel information in a wireless local area network system","description":"Methods and apparatuses for acquiring/providing available channel information using Generic Advertisement Service (GAS) protocol in a wireless local area network (WLAN) are disclosed.
