Abstract: 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. 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.

Abstract: Methods, systems, and devices for analyzing communication messages (e.g., emails) and selecting corresponding actions are described. In some database systems, a user may receive multiple messages at a user device. To efficiently determine responses to these messages, the user device may send the messages to a backend server for analysis. The server may perform natural language processing (NLP) to classify the message with one or more binary classifications and may extract metadata from each message. Based on the classifications and the metadata, the server may determine one or more actions the user device may perform to respond to each message. The server may send instructions to the user device indicating the suggested actions, and the user device may display these actions as options to a user. Additionally, the user device may use the classifications and metadata to automatically generate one or more communication templates in response to the message.
