Title:
DATA TRANSMISSION METHOD, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/214212
Kind Code:
A1
Abstract:
The present application provides a data transmission method, device, and storage medium, the method comprising: a transmitting end transmits a PPDU to a receiving end, wherein a bandwidth of the PPDU is P * 10 MHz, the PPDU comprises a first part field and a second part field, the number of subcarriers distributed per 10 MHz subcarrier corresponding to the first part field is 64 and subcarrier spacing thereof is 156.25 KHz, and the number of subcarriers distributed per 10 MHz subcarrier corresponding to the second part field is 128 and subcarrier spacing thereof is 78.125 KHz. The method can be applied for 10 MHz, 20 MHz, 40 MHz, and 60 MHz and the like, and increases transmission bandwidth relative to 802.11p, thereby improving system throughput. The transmitting end can transmit data via a portion of RUs, thereby increasing a data transmission distance, and can simultaneously transmit data of different services by simultaneously adopting multiple RUs, thereby improving data transmission efficiency.
