AI Technical Summary
Technical Problem
In existing Wi-Fi channel switching mechanisms, the single-channel switching latency cannot meet the needs of different application scenarios, resulting in wasted channel resources and switching mismatch.
Method used
By introducing a flexible channel handover delay indication mechanism into the communication method, nodes are allowed to dynamically adjust the channel handover delay and schedule channel handover according to actual needs, including sending indication information to indicate different handover delays and request frames to adjust the handover delay.
Benefits of technology
It achieves flexibility and adaptability in channel switching delay, improves channel utilization, meets the needs of different application scenarios, and reduces channel resource waste.

Abstract
The application provides a communication method and device. The method comprises the following steps: a first node sends a first frame, then sends a second frame, and then receives a first control frame. The first frame comprises first indication information indicating a first switching time delay. The second frame comprises second indication information indicating a second switching time delay. The second switching time delay is used by a second node to determine the length of a padding field included in the first control frame. When the next channel switching needs to use the second switching time delay, the first node can send the second frame to the second node, so that the second node can accurately use the second switching time delay to determine the length of the padding field included in the first control frame when scheduling the first node. Therefore, the second node can schedule the first node according to the actual switching time delay requirement of the first node, which helps to make the switching time delay used in channel switching more in line with the actual scene requirement.
