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: This application discloses a communication method, apparatus, and system. The method includes: receiving first information from a first node, where the first information is used to request to establish a first protocol data unit PDU session; sending second information to the first node, where the second information indicates an identifier of the first PDU session and a first quality of service QoS configuration policy corresponding to the first PDU session; and sending third information to the first node, where the third information indicates a data routing policy corresponding to the first PDU session, and the data routing policy includes session information of the first PDU session. In the method, a second node can configure a PDU session for the first node, so that a service provided by a core network can better meet a requirement of a terminal that does not support NAS signaling transmission.

Abstract: A communication method and apparatus are applied to the field of wireless communication technologies. A first communication device receives first indication information sent by a second communication device, where the first indication information is carried on a synchronization link and indicates the first communication device to stop receiving an asynchronous link associated with the synchronization link. The first communication device stops, based on the first indication information, receiving the asynchronous link. The first communication device may further receive second indication information sent by the second communication device, where the second indication information is carried on the synchronization link and indicates the first communication device to start receiving the asynchronous link. The first communication device starts, based on the second indication information, receiving the asynchronous link.
