AI Technical Summary
Technical Problem
In Wi-Fi 7, terminals occupying consecutive subcarriers result in low AP power, reduced coverage, and weakened signal affecting overall data transmission quality.
Method used
Data transmission is performed using a hybrid approach of distributed resource units (dRU) and ordinary resource units (NRU). The subcarrier spacing in a distributed RU does not belong to that RU, forming a hybrid RU. Terminals can use either distributed RUs or ordinary RUs for communication.
Benefits of technology
It improves the signal coverage radius and uplink/downlink power balance, reduces the impact of signal attenuation on overall transmission quality, and enhances the stability and efficiency of data transmission.

Abstract
The embodiment of the invention provides a data transmission method, an AP, a terminal and a device, relates to the technical field of communication, is applied to the AP, and comprises the following steps: performing data transmission with the terminal through a subcarrier contained in an MRU corresponding to the terminal; different terminals correspond to different MRUs; each MRU comprises a plurality of distributed RUs, and the intervals between subcarriers contained in each distributed RU do not belong to other subcarriers in the distributed RU; or data transmission with the terminal is carried out through subcarriers contained in the distributed RU or the common RU corresponding to the terminal; in all the subcarriers, except for preset idle subcarriers not participating in data transmission, the subcarriers contained in each common RU are adjacent to each other, the distributed RU and the common RU form a hybrid RU, and the hybrid RU is used by all terminals accessing the AP. By applying the embodiment of the invention, data transmission between the AP and the terminal can be realized based on the OFDMA mode.
