Abstract: A method includes: A first node sends a first message on at least one broadcast frequency hopping channel, where the first message indicates a first resource on a first frequency hopping channel. The first node sends a second message on the first resource, where the second message indicates a second resource, and the second resource includes at least one third resource used to carry a request message. A second node receives the first message and the second message from the first node, selects a third resource from the at least one third resource, and sends a request message based on the third resource. The first node detects the request message on the at least one third resource.
