Solution Overview
Problem
The increasing amount of data in wireless communication leads to lower communication efficiency, as existing technologies struggle to effectively process and manage channel state information.
Innovation Solution
A method and apparatus for processing and receiving channel state information, where a second communication node receives configuration information from a first communication node, determines a target frequency band, generates channel state information including precoding matrix information, and feeds it back to the first communication node, thereby improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel state information is transmitted using existing technologies, then communication can be maintained, but communication efficiency deteriorates due to increasing data amounts
Solution Approach 1:
The patent segments channel state information into different types (e.g., CRI, PMI, CQI) and assigns them to different frequency domains or reporting mechanisms. This segmentation allows for more efficient processing and transmission by treating different information types differently, thereby improving communication efficiency despite increasing data amounts.
Solution Approach 2:
The patent introduces frequency domain differentiation for channel state information reporting. By utilizing frequency domain resources differently for different types of channel state information, the system adds a dimensional aspect to information transmission, allowing more efficient use of available resources and improving overall communication efficiency.
2Productivity
If all channel state information is processed uniformly, then processing is simple, but communication efficiency deteriorates due to inability to optimize specific information types
Solution Approach 1:
The patent applies different processing and reporting strategies to different types of channel state information based on their specific characteristics. For example, certain information types may be reported in specific frequency domains or with different periodicities, optimizing each type's transmission efficiency while managing processing complexity through targeted rather than universal approaches.
