摘要： 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.

摘要： 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.
