Long-range transmission and reception for low-power indoor applications in 6-GHz band

A wireless communication link is established between a first station (STA) and a second STA in a 6-GHz band. The first STA and the second STA the communicate in the 6-GHz band using a low-power indoor (LPI) long range (LR) physical-layer protocol data unit (PPDU). The LPI LR PPDU includes a legacy preamble, a universal signal field (U-SIG), an extreme-high-throughput signal field (EHT-SIG), an extreme-high-throughput short training field (EHT-STF), an extreme-high-throughput long training field (EHT-LTF), and a payload. Each of the legacy preamble, U-SIG and EHT-SIG is modulated and duplicated over multiple 20-MHz subchannels for a 80-MHz, 160-MHz or 320-MHz bandwidth over which the LPI LR PPDU is transmitted. Each of the EHT-STF, EHT-LTF and payload is modulated and transmitted on an entirety of the 80-MHz, 160-MHz or 320-MHz bandwidth.
