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: This application provides a communication method and a communication apparatus. In this method, a sensing receive device sends first information to a sensing transmit device in advance, to use the first information to indicate a padding requirement of the sensing receive device for a trigger frame. The padding requirement is for sensing. The sensing transmit device sends the trigger frame having a padding bit for sensing to the sensing receive device. The padding bit is determined based on the padding requirement indicated by the first information. Therefore, the trigger frame sent by the sensing transmit device satisfies the padding requirement of the sensing receive device for the trigger frame.

Abstract: This application relates to the field of wireless communication, and is applied to a wireless local area network that supports the 802.11 series standards such as the 802.11bf standard, and in particular, to a measurement setup identifier determining method and a related apparatus. The method includes: A requesting station requests an AP as a proxy of the requesting station to perform sensing measurement. The AP obtains parameters used by the AP and a sensing responder in a proxy sensing procedure, and identifies the parameters. The AP uses an identifier different from an existing identifier at the AP when identifying the parameters. The AP then sends the parameters and the identifier to the sensing responder.

Abstract: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

Abstract: The technology of this application relates to a communication method and a related apparatus. The method in embodiments of this application includes receiving, by a first device, first indication information from a second device, where the first indication information indicates the first device to enable or disable an intelligent channel access function, and the intelligent channel access function is a function of accessing a channel based on a channel access decision output by a neural network. The method further includes enabling or disabling, by the first device, the intelligent channel access function based on the first indication information. It can be learned that the first device may enable or disable the intelligent channel access function based on the first indication information, to enrich channel access functions supported by the first device. This helps avoid a communication collision between the first device and another device, to improve communication quality of the first device.

Abstract: The present disclosure relates to data communication methods and apparatuses. One example method includes when receiving a physical layer protocol data unit (PPDU), obtaining, by a network node, a basic service set (BSS) identifier in the PPDU.If the BSS identifier in the PPDU is different from a first BSS identifier and same as a second BSS identifier, the network node determines whether the PPDU meets a preset spatial reuse condition, where the first BSS identifier is an identifier of a first BSS to which the network node belongs, the second BSS identifier is an identifier of an extended BSS to which a target relay belongs, and the target relay and the network node belong to the first BSS. If the PPDU meets the preset spatial reuse condition, the network node contends for an access channel, and communicates with a station other than the target relay in the first BSS.
