Abstract: A power communication method includes a first node that receives a first multicast frame. The first multicast frame includes multicast member information and a payload of a multicast member. When the multicast member information indicates that the multicast includes the first node, the first node sends response information. The response information indicates whether one or more units in the payload are correctly received. When the multicast member information indicates that the first node is not a multicast member, no response information is sent.

Abstract: An apparatus includes one or more channel groups, each group comprising a first coupler, first channels, and second couplers. The first coupler includes a first end and second ends. One end of each of the first channels is coupled to a corresponding one of the second ends, and the other end is coupled to a corresponding one of the second couplers. The first channel includes a first branch and a second branch. An impedance of the first branch is greater than an impedance of the second branch. The first channel is used to select the first branch or the second branch, to transmit a communication signal. so that a signal of a first channel connected to a source node or a destination node flows through a low-impedance branch, and a signal of a first channel not connected to the source node or the destination node flows through a high-impedance branch.

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.
