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: This application discloses a communication method and apparatus. A first device receives, through a multicast physical channel, a first multicast frame sent by a second device, where the first multicast frame includes first information; and when the first information indicates that the first multicast frame is the last multicast frame sent by the second device within a preset time period, the first device stops receiving multicast frames through the multicast physical channel within the preset time period. This can reduce power consumption of the first device.
