Ultra-wideband frame sending method and communication device

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.
