Communication method and communication apparatus

A communication method, wherein the method comprises:

• receiving, by a second satellite, a first message sent by a first satellite, wherein the first message comprises information about a frequency reuse scheme, the information about the frequency reuse scheme comprises basic unit information, the basic unit information comprises a central point location and frequency information of each of at least N−1 beams, N is a frequency reuse factor of the first satellite, at least N−1 different pieces of frequency information exist in the frequency information that is of the at least N−1 beams and that is comprised in the basic unit information, and N is a positive integer greater than or equal to 3;
• and
• updating, by the second satellite, a frequency reuse scheme of the second satellite based on the basic unit information of the frequency reuse scheme.

A communication apparatus, wherein the apparatus comprises:

• a transceiver module, configured to send a first message to a second satellite, wherein the first message comprises information about a frequency reuse scheme of the apparatus, the information about the frequency reuse scheme comprises basic unit information, the basic unit information comprises central point locations and frequency information of at least N−1 beams, N is a frequency reuse factor of a first satellite, at least N−1 different pieces of frequency information exist in the frequency information that is of the at least N−1 beams and that is comprised in the basic unit information, and N is a positive integer greater than or equal to 3.
