Solution Overview

Problem

Current methods for channel information processing in communication technologies face challenges in efficiently compressing and transmitting large amounts of data, particularly in scenarios involving multiple network nodes, which leads to increased overhead and potential intellectual property leakage.

Innovation Solution

A channel information processing method and apparatus that involves a first device obtaining target channel information, compressing it using different compression methods, and sending the compressed information to a second device, which then decompresses it using a corresponding method, thereby reducing redundancy and transmission overhead.

Engineering Contradictions & Design Principles

1Loss of information

If channel information is transmitted without compression, then information completeness is maintained, but transmission overhead increases

Engineering Contradiction:

Improvechannel information completenessVSAvoidtransmission overhead

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The channel information is divided into two parts: first channel information (original) and second channel information (compressed). The first device compresses only the second channel information using a second compression method, while the first channel information is transmitted uncompressed. This segmentation allows selective compression to reduce overhead while maintaining information completeness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different compression methods (first compression method vs. second compression method) to different parts of the channel information. The second compression method is specifically designed to achieve higher compression ratios for the second channel information, changing the compression parameter to optimize the balance between information retention and overhead reduction.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If channel information is compressed using a single method, then processing simplicity is maintained, but compression efficiency decreases

Engineering Contradiction:

Improvecompression efficiencyVSAvoidprocessing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The channel information processing is segmented into two streams: one using a first compression method and another using a second compression method. The first device applies the second compression method to the second channel information, while the second device uses corresponding decompression methods. This segmentation enables higher compression efficiency for specific data types while maintaining overall system manageability.

Inventive Principle:

Principle #1Segmentation

3Quantity of substance

If all channel information is compressed, then transmission overhead is reduced, but information loss increases

Engineering Contradiction:

Improvetransmission overheadVSAvoidchannel information accuracy

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent segments channel information into first channel information (transmitted uncompressed to preserve accuracy) and second channel information (compressed to reduce overhead). The first device sends both uncompressed first channel information and compressed second channel information to the second device, which then decompresses the second channel information using the corresponding decompression method, thereby reducing overall transmission overhead while maintaining information accuracy where needed.

Inventive Principle:

Principle #1Segmentation

4Productivity

If multiple compression methods are used, then compression efficiency improves, but system complexity increases

Engineering Contradiction:

Improvecompression efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses different compression methods for different data streams: a first compression method for first channel information and a second compression method for second channel information. The first device implements the second compression method, while the second device implements corresponding decompression methods. This segmentation allows the system to achieve higher compression efficiency for specific data types while maintaining clear functional separation that manages system complexity.
