Abstract
Various schemes pertaining to extremely-high-throughput long training filed (EHT-LTF) sequence design for distributed-tone resource units (dRUs) with peak-to-average power ration (PAPR) reduction in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes subcarriers of a RU with a resolution of four times (4×) subcarrier spacing to generate a 4×EHT-LTF of an uplink (UL) trigger-based (TB) physical-layer protocol data unit (PPDU) with a dRU. The communication entity then transmits the 4×EHT-LTF for the UL TB PPDU with dRU.
