Abstract: This application provides a communication method and apparatus. The 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 general frequency hopping channel; and sends a second message on the first resource, where the second message indicates a transmission opportunity group or a transmission opportunity group set. According to the method, the first node may communicate with another node (for example, a second node) without establishing a connection relationship. In addition, when the transmission opportunity group or the transmission opportunity group set includes two or more transmission opportunities, because the second node may learn of a resource of each transmission opportunity based on the second message, operations of receiving a message by the second node in all the transmission opportunities are independent of each other.

Abstract: A method includes: A first device obtains service structure information of a second device from the second device; the first device obtains a service structure hash value of the second device; the first device obtains first information from a third device, where the first information includes a service structure hash value of the third device; and when the service structure hash value of the second device is the same as the service structure hash value of the third device, the first device accesses a service of the third device. According to this method, time for the first device to access the service of the third device is reduced, and a transmission resource of the first device is also saved.
