Abstract
Various schemes pertaining to global cyclic shift delay (CSD) assignment for distributed-tone resource unit (dRU) transmissions in wireless communications are described. An apparatus applies a CSD index assignment in distributing a plurality of subcarriers of a resource unit (RU) over a bandwidth to generate an extremely-high-throughput short training field (EHT-STF) of a dRU. The apparatus then transmits symbols of the EHT-STF of the dRU. The CSD index assignment is based on a dRU hierarchical structure with one or more CSD indexes shared among multiple dRUs of different sizes but not among multiple dRUs of a same size.
