Abstract: An ultra-wideband (UWB) signal transmission method includes that a plurality of initiators simultaneously sends a UWB signal. A UWB signal sent by any initiator is obtained by performing pulse shaping and modulation on a first sequence. The first sequence is obtained by performing a cyclic shift on a second sequence, and a number of cyclic shift bits is determined based on a shift factor and a step size of the cyclic shift that are of the any initiator. A responder determines time of arrival of the plurality of UWB signals based on the plurality of received UWB signals and the second sequence.

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.

Abstract: A data transmission method and a network device are provided. The method can include: determining, by a first network device, that a terminal device enters an RRC inactive state; sending, by the first network device, a first message to a second network device, where the first message is used to configure the second network device, so that the second network device transmits data for the terminal device in the RRC inactive state; and receiving, by the first network device, an acknowledgment message the first message and sent by the second network device. The second network device can transmit data of the terminal device to the first network device to enable the first network device to send the data to a core network, without having to establish a path between the second network device and the core network for the second network device to send the data to the core network.
