Abstract

A communication method and device are applied to a wireless local area network system supporting an IEEE 802.11 ax next generation Wi-Fi protocol, such as 802.11 be, Wi-Fi 7 or EHT, and 802.11 series protocols, such as 802.11 bn or Wi-Fi 8, 802.11 ay, 802.11 aj and the like, of the 802.11 be next generation, and can also be applied to a UWB-based wireless personal local area network system, a sensing system and the like. A first communication device sends a PPDU, and a second communication device receives the PPDU. The PPDU corresponds to at least one target user, the PPDU comprises a data field corresponding to the target user and a parameter NSD corresponding to the target user, and the short is determined by an RU / MRU used for transmitting the data field and an MCS of the data field. The coding and decoding time is effectively shortened, and the coding and decoding efficiency is improved.
