(EN) The invention discloses a detection method of a multi-link device and a communication device, which can be applied to a wireless local area network supporting an 802.11 be standard, and the method comprises the steps that an STA multi-link device generates a detection request frame, the detection request frame carries first indication information, and the first indication information is sent to the STA multi-link device, wherein the AP multi-link device is used for indicating the AP multi-link device to feed back communication information of an AP working on at least one link in the AP multi-link device, the communication information is used for multi-link communication between the STA multi-link device and the AP multi-link device, at least one link comprises a second link, and the second link is different from the first link; and the STA multi-link device sends a detection request frame on the first link, and further, the STA multi-link device receives the communication information of the AP on at least one link fed back by the AP multi-link device on the first link. Therefore, based on the method disclosed by the invention, the STA multi-link device can obtain the communication information of the AP working on the second link in time.
(ZH) 本申请公开了多链路设备的探测方法及通信装置，可应用于支持802.11be标准的无线局域网中，该方法包括：STA多链路设备生成探测请求帧，该探测请求帧携带第一指示信息，用于指示AP多链路设备反馈AP多链路设备中工作在至少一条链路上的AP的通信信息，通信信息用于STA多链路设备与AP多链路设备进行多链路通信，该至少一条链路包括第二链路，该第二链路与第一链路不相同；STA多链路设备在第一链路上发送探测请求帧，进一步的，STA多链路设备在第一链路上接收AP多链路设备反馈的在至少一条链路上的AP的通信信息。可见，基于本申请公开的方法，STA多链路设备能够及时地获取工作于第二链路的AP的通信信息。
