Abstract
Various schemes pertaining to transmission power control (TPC) for distributed-tone resource units (dRUs) and distributed multi-resource units (dMRUs) in 6 GHz low-power indoor (LPI) systems are described. A communication entity distributes subcarriers of a resource unit (RU) and a multi-RU over a physical-layer protocol data unit (PPDU) bandwidth or a frequency subblock of a bandwidth to generate a dRU and a dMRU associated with an uplink (UL) trigger-based (TB) PPDU comprising at least an extremely-high-throughput (EHT) short training field (EHT-STF), an EHT long training field (EHT-LTF), and a payload of data. The communication entity then transmits the dRU or dMRU associated with the UL TB PPDU with transmission power control such that symbols associated with the EHT-STF are transmitted with a first power and symbols associated with the EHT-LTF and the payload are transmitted with a second power.
