Abstract: A method is described for transmitting a frame in a wireless network. The method includes setting, by a wireless device, a first field of the frame according to a first characteristic of the frame; setting, by the wireless device, a second field of the frame according to a second characteristic of the frame; setting, by the wireless device, a puncturing field of the frame in response to the first field of the frame meeting a first criteria and the second field of the frame meeting a second criteria, wherein the puncturing field is associated with puncturing a set of sub-channels of a transmission bandwidth of the frame; and transmitting, by the wireless device, the frame based on the transmission bandwidth and according to the set of sub-channels.

Abstract: A method includes determining, by a Media Access Control (MAC) layer of a first wireless station, a total length of user data in a first Physical Layer (PHY) Protocol Data Unit (PPDU); determining, by the MAC layer, a Hybrid Automatic Repeat Request (HARQ) block size; adding a first indication to a transmission vector, wherein the first indication indicates the total length of user data in the first PPDU; adding a second indication to the transmission vector, wherein the second indication indicates the HARQ block size; passing the transmission vector to a PHY layer of the first wireless station; generating, by the PHY layer, the first PPDU based on the first indication and the second indication, wherein the first PPDU includes a first set of HARQ blocks that each have a size equal to the HARQ block size; and transmitting the first PPDU to a second wireless station.

Abstract: A method is described for generating and transmitting a frame by a station. The method includes determining a bandwidth of a frame to be transmitted by the station; generating a long training field for the frame, wherein the long training field includes a set of pilot tones located at a set of subcarrier positions, wherein when the bandwidth of the frame is 10 MHz, the set of subcarrier positions include four subcarrier positions and the four subcarrier positions are set as {−21-α1,−7-α2,7+α3,21+α4} where α1, α2, α3, and α4 are odd values, and wherein when the bandwidth of the frame is 20 MHz, the set of subcarrier positions include six sub carrier positions, including {−53-β1,−25-β2,−11-β3, 11+β4,25+β5,53+β6} where β1, β2, β3, β4, β5, and β6 are odd values.

Abstract: A method for encoding a bitstream is described. The method includes receiving, by an error correction unit, the bitstream; performing, by the error correction unit, encoding on the bitstream to generate an encoded bit stream that includes the bitstream and parity bits; processing, by a constellation unit, the encoded bitstream to generate constellation points in one or more encoded streams; determining, by a low-density parity-check (LDPC) tone mapper, a distance between subcarriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the frame; and performing, by the LDPC tone mapper, LDPC tone mapping based on the one or more encoded streams and on the determined distance to generate a permuted stream of complex numbers, wherein the distance between subcarriers is determined to be either (1) 18 for a first resource unit size used in the frame and (2) 20 for a second resource unit size used in the frame.
