5G Base Station Channel Measurement Resource Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G New Radio communications, base stations face challenges in determining which resources are used for channel measurement values, as user equipment feeds back multiple channel and interference measurement values without clear resource identification, making it difficult for the base station to determine the specific resources used for measurement.
Innovation Solution
The proposed solution involves a communication method where the user equipment feeds back channel measurement values along with corresponding resource identifiers, allowing the base station to determine the resources used for measurement by using channel measurement resource identifiers and interference measurement resource identifiers, and configuring multiple channel and interference measurement resources for dynamic combination and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resources are configured for channel and interference measurement, then measurement comprehensiveness is improved, but resource identification capability deteriorates
Solution Approach 1:
The patent introduces resource identifiers as intermediary elements that link measurement resources to channel measurement values. The UE feeds back not only the measurement values but also the associated resource identifiers, enabling the base station to accurately identify which resources were used for measurement. This intermediary mechanism resolves the contradiction by maintaining comprehensive measurement capability while preserving clear resource identification through the feedback of resource identifier information.
2Quantity of substance
If multiple channel measurement values are fed back without resource identification, then feedback comprehensiveness is improved, but base station processing complexity increases
Solution Approach 1:
The patent applies preliminary action by having the UE prepare and attach resource identifiers to channel measurement values before feedback transmission. The UE determines which resources correspond to each measurement value and includes this identification information in the feedback message. This preliminary organization of information reduces base station processing complexity by eliminating the need for the base station to infer resource mappings, while still maintaining comprehensive feedback of multiple measurement values.
3Productivity
If resource settings are selected according to report settings, then feedback efficiency is improved, but measurement flexibility deteriorates
Solution Approach 1:
The patent implements dynamics by allowing the UE to dynamically determine and report the resource settings corresponding to channel measurement values. Rather than using fixed predetermined mappings, the system adapts the resource identification based on the actual measurement configuration and UE capabilities. This dynamic approach maintains feedback efficiency through structured reporting while preserving measurement flexibility by allowing adaptive resource selection and identification.

AI summary
This application provides a communication method and an apparatus, so that a base station can determine a resource corresponding to a channel measurement value. The method includes: receiving, by a network device, k channel measurement values, k channel measurement resource identifiers, and k interference measurement resource identifiers that are sent by user equipment, where k is an integer greater than or equal to 1, each channel measurement value corresponds to one channel measurement resource identifier and one interference measurement resource identifier, and the channel measurement value is calculated based on the channel measurement resource identifier and the interference measurement resource identifier that correspond to the channel measurement value.
