    摘要： A method and apparatus of accessing a channel including receiving, by a device, an operation element for setting up or switching at least one channel from an access point (AP), the operation element including a channel type field indicating whether the at least one channel is either a single channel or multiple channels, and including two channel center frequency segment fields indicating a channel center frequency of a primary and a secondary channel if the channel type field indicates that the channel is multiple channels, determining whether the primary channel is idle during a first interval, determining whether the secondary channel is idle during a second interval if the primary channel is idle, and transmitting data by using the primary and secondary channels to the AP or at least one station in a basic service set (BSS) if the primary and secondary channel are idle.

    摘要： Methods and apparatuses for acquiring/providing available channel information using Generic Advertisement Service (GAS) protocol in a wireless local area network (WLAN) are disclosed. 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.
