Abstract: Embodiments of this application relate to the field of communication technologies, and provide an ultra-wideband frame sending method and a communication device, to improve a security protection capability in UWB sending and receiving processes. A specific solution is as follows: A communication device obtains key information of an ultra-wideband frame, where the ultra-wideband frame includes a plurality of data fragments. The communication device sends the plurality of data fragments based on one or more gaps between the plurality of data fragments, or the communication device receives the plurality of data fragments based on one or more gaps between the plurality of data fragments, where the gaps between the plurality of data fragments are determined based on the key information. Embodiments of this application are used in a process of sending the ultra-wideband frame by the communication device.

Abstract: This application provides a signal transmission method, apparatus, and system. The method includes: generating an ultra-wideband signal, where the ultra-wideband signal includes a channel impulse response training sequence (CTS) field, and the CTS field is obtained by separately spreading at least one first preamble symbol based on a pseudo-random sequence; and sending the ultra-wideband signal, where the CTS field is used to determine a channel impulse response. This application can effectively improve ranging and positioning efficiency while implementing secure high-precision ranging and positioning.

Abstract: An initiating device randomly generates a sending time interval at which the initiating device sends ranging signal frames to a responding device such that an attacker cannot determine a rule of sending the ranging signal by the initiating device to the responding device and cannot send an interference signal at a same moment to perform interference and an attack, thereby enhancing information security of electronic devices during interactive communication.
