    Abstract: A method is provided for accessing a channel in a wireless local area network. A device receives an operation element to set up an operating channel from an access point (AP). The operation element includes a channel type field, a first frequency segment field and a second frequency segment field. The channel type field indicates a use of two 80 MHz channels. The first frequency segment field indicates a center frequency of a primary 80 MHz channel. The second frequency segment field indicates a center frequency of a secondary 80 MHz channel. is obtained based on activities on a part of the primary 80 MHz channel. The device determines whether the secondary 80 MHz channel was idle during an interval immediately preceding the start of the TXOP only after a transmission opportunity (TXOP) is obtained.

    Abstract: 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.
