Communication method and communication apparatus

A communication apparatus, comprising:

• a receiver, the receiver configured to receive first configuration information of a first cell of a second communication apparatus, wherein the first configuration information comprises first identification update information and information about a first update moment of the first cell, and the first identification update information is used to determine first identification information used by the first cell at the first update moment or after the first update moment;
• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to communicate based on the first configuration information by using the first identification information at the first update moment or after the first update moment, wherein the communication apparatus is in a coverage range of the first cell.
