Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including generating an extended range physical layer protocol data unit (ER-PPDU) for transmission to a receiver, the ER-PPDU including an ultra-high reliability extended range long training field (UHR-ER LTF) and an ultra-high reliability extended range signal field (UHR-ER SIG), and transmitting the ER-PPDU to the receiver, in which at least one of the UHR-ER-LTF or the UHR-ER-SIG is repeated two or more times in the time domain or the frequency domain.
