Communication method and communication apparatus

A method comprising:

• receiving, by a second communication apparatus, second data from a first communication apparatus, wherein the second data is partial data of first data, and the first data is network measurement data;
• obtaining, by the second communication apparatus, third data in a first data recovery manner based on the second data, wherein a difference between the third data and the first data is less than or equal to a target threshold;
• receiving, by the second communication apparatus, fourth information from the first communication apparatus, wherein the fourth information comprises at least one of the following:
• the error between the third data and the first data;
• and
• a ratio of a data amount of the second data to a data amount of the first data;
• updating, by the second communication apparatus, the target threshold based on the fourth information;
• and
• sending, by the second communication apparatus, an updated target threshold to the first communication apparatus.

A method applied to a communication system comprising a first communication apparatus and a second communication apparatus, wherein the method comprises:

• obtaining, by the first communication apparatus, first data, obtaining second data in a first processing manner based on the first data, and sending the second data to the second communication apparatus, wherein the first data is network measurement data, and the second data is partial data of the first data;
• receiving, by the second communication apparatus, the second data from the first communication apparatus, and obtaining third data in a first data recovery manner based on the second data, wherein a difference between the third data and the first data is less than or equal to a target threshold;
• sending, by the first communication apparatus, fourth information to the second communication apparatus, wherein the fourth information comprises at least one of the following:
• the error between the third data and the first data;
• and
• a ratio of a data amount of the second data to a data amount of the first data;
• receiving, by the first communication apparatus, an updated target threshold from the second communication apparatus.
