Abstract
Techniques pertaining to physical-layer (PHY) parameter designs enabling resource unit (RU) duplication and tone repetition for next-generation wireless local area networks (WLANs) are described. An apparatus (e.g., station (STA)) generates an RU or multi-RU (MRU). The apparatus then performs a wireless communication with the RU or MRU. In generating the RU or MRU, the apparatus codes a spatial stream using a binary convolutional coding (BCC) interleaver or a low-density parity-check (LDPC) tone mapper. In performing the wireless communication, the apparatus performs the wireless communication with RU duplication or tone repetition in a frequency domain.

A method, comprising:
- generating, by a processor of an apparatus, a resource unit (RU) or multi-RU (MRU);
- and
- performing, by the processor, a wireless communication with the RU or MRU,

- wherein the performing of the wireless communication comprises performing the wireless communication with RU duplication or tone repetition in a frequency domain,
- wherein the generating of the RU or MRU comprises generating a 26-tone RU (RU26), 52-tone RU (RU52), 106-tone RU (RU106) or 242-tone RU (RU242) for one or more spatial streams,
- wherein the performing of the wireless communication comprises performing the wireless communication with tone repetition in the frequency domain and with or without leftover tones, and
