Data transmission methods, AP, terminal and apparatus

Abstract

The embodiments of the present application relate to the technical field of communications. Provided are data transmission methods, an AP, a terminal and an apparatus. A method applied to an AP comprises: by means of subcarriers comprised in an MRU corresponding to a terminal, performing data transmission with the terminal, different terminals corresponding to different MRUs, each MRU comprising a plurality of distributed RUs, and the subcarriers within each distributed RU being spaced apart from other subcarriers that do not belong to the distributed RU; or, by means of subcarriers comprised in a distributed RU or common RU corresponding to the terminal, performing data transmission with the terminal, wherein among all of the subcarriers, excepting preset idle subcarriers which do not participate in data transmission, the subcarriers comprised in each common RU are adjacent to each other, the distributed RUs and the common RUs constituting mixed RUs, and the mixed RUs being used by all of terminals accessing the AP. Applying the embodiments of the present application can implement data transmission between APs and terminals on the basis of an OFDMA mode.
