AI Technical Summary

Technical Problem

In wireless communication, precise channel information requires a large amount of data, resulting in low transmission efficiency, serious resource waste, and difficulty in meeting the requirements of high data rate and low latency.

Method used

Differential channel information is sent to the terminal through network devices. The terminal determines the current channel information based on the differential information and reference channel information, thereby reducing the amount of data transmitted and improving the transmission efficiency and stability of channel information.

Benefits of technology

It reduces the consumption of transmission resources, improves the transmission efficiency and accuracy of channel information, reduces the accumulation of transmission errors, and adapts to the needs of transmitting different channel information.

Abstract

The present application relates to the field of communications, and provides a channel information transmission method, a communication apparatus, and a communication system. The method comprises: a terminal receives first information, the first information being used for indicating a plurality of pieces of channel information corresponding to a plurality of pieces of location information, the first information comprising first differential information corresponding to first location information, the first differential information being differential information between first channel information and first reference channel information, and the first channel information being channel information, among the plurality of pieces of channel information, corresponding to the first location information; and the terminal determines the first channel information on the basis of the first differential information and the first reference channel information. The solution can reduce the amount of transmitted data when a network device delivers channel information to a terminal, thereby reducing consumed transmission resources and ensuring the timeliness of channel information delivery.
