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.

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: Embodiments of this application provide a communication method and apparatus. The method includes: sending, on a first narrowband channel, a first frame used to trigger data measurement; sending a first UWB signal and receiving a second UWB signal on a first ultra-wideband UWB channel, where the first UWB signal and the second UWB signal are used to perform the data measurement to obtain a data measurement result; and specifically, sending, on a second narrowband channel, a first trigger frame used to trigger reporting of a first measurement result. A trigger frame is delivered to trigger a measurement result reporting procedure. This avoids a reporting failure when the measurement result is directly reported on the first narrowband channel.
