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 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.
