An enhanced directional multi-gigabit (EDMG) modulation field in the PPDU includes a channel estimation field (CEF), the CEF includes a CEF sequence, and a length of the CEF sequence is m, where m is determined based on a quantity of bonding channels and a quantity of subcarriers included on a channel. When a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) technology is introduced into a 60 GHz WLAN standard, an applied CEF sequence included in a CEF can be determined, and DFT-S-OFDM transmission is further performed by using the CEF sequence. In this way, a PAPR of a WLAN system can be reduced while frequency division multiplexing for a plurality of users is supported."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data transmission method and apparatus","description":"This application discloses a method including a transmit end that generates and sends a physical layer protocol data unit (PPDU), and a receive end that receives the PPDU and parses the PPDU.
