The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A Wi-Fi transmitter station (110; 120) for robust, yet efficient orthogonal frequency division multiplexing, OFDM, based communication with a Wi-Fi receiver station (120; 110) via a wireless channel (130) is disclosed. The Wi-Fi transmitter station (110; 120) is configured to generate a signal carrying a physical-layer protocol data unit, PPDU, wherein the PPDU comprises a preamble part and a data part, and wherein the signal carrying the PPDU is modulated over a plurality of subcarriers spanning a plurality of OFDM symbols. Moreover, the Wi-Fi transmitter station (110; 120) is configured to transmit the signal to the Wi-Fi receiver station (120; 110), wherein the preamble part of the PPDU further comprises a dedicated field comprising one or more OFDM symbols with a guard interval, GI, duration larger than a GI duration of the plurality of OFDM symbols of the data part. The Wi-Fi receiver station (120; 110) is configured to receive the signal with the PPDU.
