Abstract: This application provides a communication method and a communication apparatus. The method includes: A terminal device obtains first indication information and downlink channel information, where the first indication information indicates a first path domain parameter, the first path domain parameter is a path domain parameter shared by a first uplink channel and a first downlink channel, and the first uplink channel and the first downlink channel are channels for communication between a network device and the terminal device. The terminal device estimates a second path domain parameter based on the first path domain parameter and the downlink channel information, and sends the second path domain parameter to the network device. The first path domain parameter and the second path domain parameter are used by the network device to reconstruct the first downlink channel.

Abstract: A multicast broadcast service sending method includes receiving indication information from a core network device. The indication information indicates that a receiver of a target multicast broadcast service includes a narrowband terminal and a broadband terminal. The method also includes sending a multicast control channel (MCCH) to the narrowband terminal and the broadband terminal. The MCCH is used to carry configuration information of a multicast traffic channel (MTCH) of the target multicast broadcast service, and a first frequency domain resource corresponding to the MCCH or a scheduling bandwidth occupied by the MCCH does not exceed a maximum bandwidth capability of the narrowband terminal. The method further includes sending the target multicast broadcast service to the narrowband terminal and the broadband terminal on a frequency domain resource corresponding to the MTCH.
