COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/051515
Kind Code:
A1
Abstract:
The present application provides a communication method and apparatus, which are used for reducing the dependence of a UWB system on a narrowband channel, and improving the reliability and robustness of a UWB ranging system. The method comprises: a first device sending a first segment of a first UWB signal to a second device, and then sending a second segment of the first UWB signal to the second device, wherein the first segment carries a first preamble, and the second segment carries a second preamble, the first preamble and the second preamble being used for triggering a first operation, and the first preamble being different from the second preamble. By means of preamble change indication information, the probability of a second device receiving information can be increased, and thus the reliability and robustness of a UWB system can be improved.
