1. An apparatus, comprising:
a Radio Frequency (RF) interface; and
processor circuitry coupled with the RF interface and configured to:
generate an Extremely High Throughput (EHT) Physical Protocol Data Unit (PPDU); and
provide the EHT PPDU to the RF interface for transmitting on a transmission bandwidth, wherein
any of distributed Resource Units (dRUs) for transmitting a data portion of the EHT PPDU is associated with a whole or part of an EHT-Short Training Field (STF) sequence constituting the EHT PPDU,
any of the dRUs is a resource unit, subcarriers of which are distributed across one or more frequency sub-blocks within the transmission bandwidth for transmitting the EHT PPDU, and
when the transmission bandwidth for transmitting the EHT PPDU is 80 MHz and preamble puncturing is not applied, any of the dRUs is associated with the whole of the EHT-STF sequence.
