Abstract

This disclosure describes systems, methods, and devices related to extremely high throughput (EHT) resource unit (RU) allocation. A device may utilize a tone plan to generate an EHT frame to be sent using an 80 MHz frequency band, wherein the tone plan comprises a plurality of null tones. The device may encode one or more resource units (RUs) for the EHT frame, wherein the one or more RUs comprise at least one of a 26-tone RU, a 52-tone RU, a 106-tone RU, a 242-tone RU, a 484-tone RU, or a 996-tone RU, wherein the 106-tone RU, the 242-tone RU, and the 484-tone RU comprise null tones located at least at subcarriers ±258, ±257, ±256, ±255, and ±254. The device may cause to send the EHT frame to a first station device using the 80 MHz frequency band.
