Abstract: A method includes sending, by a communication apparatus, configuration information. The configuration information includes a quantity of cyclic shift positions that corresponds to each device, the quantity of cyclic shift positions is used to cyclically shift a perfect sequence, and quantities that are of cyclic shift positions and that correspond to devices used for completing different services are different. The method is applied to an ultra-wideband (UWB)-based wireless personal local area network system, a sensing system, and the like, including 802.15 series protocols, such as an 802.15.4a protocol, an 802.15.4z protocol, or an 802.15.4ab protocol. The method is further applied to a wireless local area network system that can support a next-generation WI-FI protocol of 802.11ax, such as 802.11be, Wi-Fi 7, or extremely high-throughput (EHT), and 802.11 series protocols, such as a next generation of 802.11be or WI-FI 8.

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: A packet processing method, where a server allocates an identifier of a network slice to a terminal device based on a service type of the terminal device and sends the identifier of the network slice to a control device. The control device determines parameter information of the network slice based on the identifier and determines a forwarding path based on the parameter information. Then, the control device adds a forwarding resource included in the forwarding path to a forwarding resource of the network slice. When the terminal device sends the service packet, the service packet is forwarded using the forwarding resource of the network slice. Hence, the control device dynamically determines the forwarding resource for the network slice based on a service requirement such that a forwarding resource in a network can be fully used, saving forwarding resource and improving network flexibility.
