Abstract: Example signal transmission methods and apparatus are described. In one example method, a first initiating device sends a poll frame. The poll frame includes time-frequency location information of N first ultra-wideband (UWB) segment signals, and the poll frame further includes first delay information for each of M second responding devices to reply to the first initiating device with a response frame. The first initiating device receives a plurality of response frames based on a timestamp of the poll frame and the first delay information for each of the M second responding devices to reply to the first initiating device with the response frame.

Abstract: This application is applied to an ultra-wideband (UWB)-based wireless personal area network system, including 802.15 series protocols, for example, the 802.15.4a protocol, the 802.15.4z protocol, or the 802.15.4ab protocol; a wireless local area network system that can support 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and for another example, a next generation protocol of 802.11be, and Wi-Fi 8; a sensing system; or the like. This application provides a signaling transmission method, including receiving a UWB test signal, determining indication information of a number of fragment signals of a UWB measurement signal based on the UWB test signal, and sending the indication information. The number of fragment signals of the UWB measurement signal is determined based on the UWB test signal. This reduces a probability of incorrectly configuring the number of fragment signals.

Abstract: A method for feeding back a sensing measurement result based on UWB and an apparatus are applied to a UWB-based WPAN system, for example, the 802.15.4a protocol, the 802.15.4z protocol, or the 802.15.4ab protocol in 802.15 series protocols, or may be applied to a wireless local area network system, a sensing system, or the like in 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next generation protocol of 802.11be, for example, Wi-Fi 8. The method includes: A transmitter sends control information; and correspondingly, a receiver receives the control information. Then, the receiver sends feedback information, and correspondingly, the transmitter receives the feedback information. According to the technical solutions provided in this application, signaling overheads can be effectively reduced.
