This application relates to the field of communication technologies and discloses a communication method and a communication apparatus. One example method includes: A network device sends temporary SSB burst configuration information to a terminal device served by a secondary serving cell, where the temporary SSB burst configuration information includes a periodicity and/or an offset for sending a temporary SSB burst by the network device in the secondary serving cell configured for the terminal device. The network device sends a temporary SSB burst in the secondary serving cell based on the temporary SSB burst configuration information, where a temporary SSB included in the temporary SSB burst does not include a PBCH.
