1. A method for encoding a bitstream for a frame in a wireless transmission, the method comprising:
performing, by a wireless device, encoding on the bitstream to generate an encoded bit stream that includes the bitstream and parity bits;
processing, by the wireless device, the encoded bitstream to generate constellation points in one or more encoded streams;
determining, by the wireless device, a distance between subcarriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the frame;
performing, by the wireless device, low-density parity-check (LDPC) tone mapping based on the one or more encoded streams and on the determined distance between subcarriers to generate a permuted stream of complex numbers; and
setting an indication in the frame as to whether data is duplicated between a plurality of resource units of the frame,
wherein the distance between subcarriers is determined to be 18 for a first resource unit size used in the frame.
