Abstract: The technology of this application relates to a communication method, apparatus, and system. The method includes determining a target transmission requirement of a first node, determining, based on the target transmission requirement, whether to establish a first transmission channel, where the first transmission channel is used to communicate with a second node, and sending a first request message to the second node, where the first request message is used to request to establish the first transmission channel. The method further includes receiving a first response message from the second node, where the first response message is used to confirm establishment of the first transmission channel. In the method, the first transmission channel is dynamically established between the first node and the second node based on the target transmission requirement of the first node, to help flexibly schedule a transmission resource for the first node.

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.

Abstract: Example reference signal transmission methods and apparatus are described. One example method includes that a first node maps a reference signal to a first transmission resource and sends the reference signal. The first transmission resource is included in a second transmission resource used by the first node to send data, and the second transmission resource includes a first symbol and at least one subcarrier corresponding to the first symbol. The first transmission resource includes at least one of an Mth subcarrier or an Nth-to-last subcarrier in the at least one subcarrier corresponding to the first symbol, and M and N are preset, specified in a protocol, or configured. The reference signal is used to determine phase information of a channel.

Abstract: This application provides a downlink signal receiving method, a terminal, and a source base station. The method includes: A terminal may receive downlink signals from a source base station and a target base station in a handover process. When receiving no downlink signal from the target base station, the terminal receives the downlink signal only from the source base station. In addition, after handover is completed, the terminal receives the downlink signal only from the target base station, so that the terminal can still receive the downlink signal from the source base station in the handover process. Therefore, downlink signal transmission interruption caused by the handover process may be reduced to 0 ms or nearly 0 ms. In other words, zero interruption or nearly zero interruption of data transmission may be implemented.
