1. A method, comprising:
processing, by a processor of an apparatus, a plurality of subcarriers of a resource unit (RU) to generate a distributed-tone RU (dRU) or a distributed-tone multi-RU (dMRU); and
transmitting, by the processor via a transmitter of the apparatus, the dRU or the dMRU to another apparatus,
wherein the processing of the plurality of subcarriers comprises coding a plurality of information bits by either low-density parity-check (LDPC) encoding or binary convolutionally-coded (BCC) encoding and transmitting the plurality of subcarriers with one or more optimization parameters using a LDPC tone mapper or a BCC interleaver,
wherein the one or more optimization parameters comprise tone mapper parameters with respect to a tone mapping distance (DTM),
wherein the one or more optimization parameters further comprise BCC interleaver parameters with respect to a number of columns (Ncol), a number of rows (Nrow), a number of rotations (Nrot) and a number of coded bits per subcarrier spacing (Nbpscs), and
wherein:
DTM=3 or 6 for a 26-tone dRU;
DTM=1 or 8 or 12 for a 52-tone dRU;
DTM=1 or 9 or 12 for a 78-tone dMRU;
DTM=1 or 3 or 17 for a 106-tone dRU;
DTM=1 or 9 for a 132-tone dMRU;
DTM=1 or 13 or 18 for a 242-tone dRU or dMRU;
DTM=1 or 18 or 26 for a 484-tone dRU or dMRU;
Ncol=8, Nrow=3×Nbpscs, and Nrot=2 for the 26-tone dRU;
Ncol=16, Nrow=3×Nbpscs, and Nrot=11 for the 52-tone dRU;
Ncol=8, Nrow=6×Nbpscs, and Nrot=11 for the 52-tone dRU on a 20 MHz bandwidth;
Ncol=18, Nrow=4×Nbpscs, and Nrot=18 for the 78-tone dMRU;
Ncol=12, Nrow=6×Nbpscs, and Nrot=18 for the 78-tone dMRU on the 20 MHz bandwidth;
Ncol=17, Nrow=6×Nbpscs, and Nrot=29 for the 106-tone dRU;
Ncol=21, Nrow=6×Nbpscs, and Nrot=31 for the 132-tone dMRU;
Ncol=14, Nrow=9×Nbpscs, and Nrot=31 for the 132-tone dMRU on the 20 MHz bandwidth; and
Ncol=26, Nrow=9×Nbpscs, and Nrot=58 for the 242-tone dRU or dMRU.
