Abstract: A communication method and an apparatus are provided. The method includes: a first node receives a resource scheduling message transmitted by an upper-level node. The resource scheduling message carries template identification information indicating a target time slot allocation template to be used. The first node determines a transmission time slot of the first node based on indication information that is included in the target time slot allocation template and that is used for allocating time slots to a plurality of nodes. Because a byte length occupied by the template identification information is far less than a byte length occupied by time slot allocation information corresponding to each node, a length of the resource scheduling message can be greatly shortened, and even if a quantity of nodes in the communication system increases, the length of the resource scheduling message does not increase.
