    Abstract: A method is provided for transmitting data in a wireless local area network. A transmitter generates an encoded data unit by performing a channel coding to transmission data to be included in a data field of a physical layer protocol data unit (PPDU). The transmitter generates at least one spatial block by re-arranging the encoded data unit, and divides each spatial block of at least one spatial block into two frequency segments. A bandwidth of each frequency segment is half of a bandwidth of the each spatial block. The transmitter interleaves the two frequency segments to generate a first interleaved segment and a second interleaved segment, respectively, and generates first and second mapped sequences by respectively mapping the first and second interleaved segments into a signal constellation. The transmitter performs an Inverse Discrete Fourier Transform (IDFT) on the first and second mapped sequences to generate and transmit a transmission signal.

The method according to one embodiment includes selecting, by a transmitting station, a transmission channel; and transmitting, by the transmitting station, a Physical layer Protocol Data Unit (PPDU) over the selected transmission channel to a receiving station. The transmission channel includes a primary channel and a first channel if the first channel was idle. The transmission channel includes the primary channel, the first channel and a second channel if both the first channel and the second channel were idle. The primary channel is positioned between the first channel and the second channel if the transmission channel includes the primary channel, the first channel and the second channel.

    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: A method for a channel sounding in a wireless local area network. A station receives a 20 MHz null data packet announcement (NDPA) frame and at least one duplicate 20 MHz NDPA frame. The at least one duplicate 20 MHz NDPA frame is a duplicate of the 20 MHz NDPA frame. The station also receives a null data packet (NDP) following the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame. The bandwidth over which the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame are transmitted is the same as a bandwidth over which the NDP is transmitted. The station transmits a report frame for the channel sounding. The 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame comprise bandwidth information indicating the bandwidth over which the frames are transmitted.
