Abstract: Examples in this application provide a communication method and a communications apparatus. One example communication method includes determining to deactivate or activate a first synchronization signal and physical broadcast channel block (SSB), and sending a first request message to a second network device. Specifically, the first request message carries first indication information for indicating the first SSB, and when the first SSB is an SSB in the first network device, the first request message requests the second network device to update a state of the first SSB, and the second network device maintains information about at least one SSB in the first network device, or when an active first SSB is an SSB in the second network device, the first request message requests the second network device to activate the first SSB, and the first network device maintains information about at least one SSB in the second network device.

Abstract: A data transmission method, a communications device, and a communications system are provided for wireless communications. A terminal device receives a first system information broadcast by a radio access network device. The first system information includes a non-public network (NPN), identification information list and a first association information. The NPN identification information list includes at least one NPN identification information and determines a second system information is valid when first NPN identification information in the NPN identification information list is identical to second NPN identification information stored in the terminal device, and the first association information is identical to a second association information stored in the terminal device. The second system information can include the second NPN identification information and the second association information.
