Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no suitable solution for performing interference measurement on reference signal resources in the New Radio (NR) system, which is essential for accurate channel quality acquisition and data scheduling.
Innovation Solution
A method and apparatus for interference measurement using a subset of resources for reference signals, specifically configuring interference measurement resources within the NR system, including channel state information-reference signals (CSI-RS), demodulation reference signals (DMRS), and sounding reference signals (SRS), with configuration indications transmitted by the network device to the terminal device to determine appropriate measurement resources and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If interference measurement is performed on all reference signal resources, then measurement accuracy is improved, but resource overhead and system complexity increase
Solution Approach 1:
The patent segments reference signal resources into specific interference measurement resources (IMR) that are distinct from other reference signal uses. By dividing the resource pool and designating specific resources for interference measurement purposes, the system achieves accurate interference measurement without requiring all reference signal resources to be used for measurement, thereby reducing overall system complexity while maintaining measurement precision.
2Reliability
If interference measurement resources are allocated for all reference signal functionalities, then measurement completeness is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent applies local quality by configuring interference measurement resources with specific properties tailored for interference measurement tasks. Instead of using all reference signal resources with their diverse configurations for interference measurement, the system designates specific resources with appropriate characteristics (such as ZP CSI-RS resources) that are locally optimized for interference measurement, achieving measurement completeness while minimizing resource overhead.
3Ease of operation
If a unified reference signal resource configuration is used for all purposes, then configuration simplicity is improved, but functional adaptability deteriorates
Solution Approach 1:
The patent implements universality by designing interference measurement resources that can serve multiple purposes within the NR system. The configured IMR resources can be used for interference measurement while also being integrated with other reference signal functionalities, allowing a single resource configuration to fulfill multiple roles and thereby maintaining configuration simplicity while achieving functional adaptability.
