Shared IMR Configuration for SINR Reporting in Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently reporting signal-to-interference noise ratio (SINR) due to high signaling overhead and latency, particularly in configuring channel measurement resources (CMR) and interference measurement resources (IMR) between terminals and base stations.
Innovation Solution
The method involves receiving CMR and IMR configurations from a base station, assuming multiple CMR configurations with the same Quasi Co-located (QCL) source share the same IMR configuration, and calculating and reporting the SINR based on these configurations, reducing signaling overhead and latency by establishing CMR and IMR configurations with a common spatial parameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate IMR configurations are provided for each CMR configuration, then SINR measurement accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent merges multiple IMR configurations into a single shared IMR configuration that can be used by multiple CMR configurations. Specifically, a first CMR configuration and a second CMR configuration both share the same IMR configuration, reducing the total number of IMR configurations from two to one while maintaining SINR measurement capability across different channel conditions
Solution Approach 2:
The patent makes a single IMR configuration universal by enabling it to serve multiple CMR configurations simultaneously. The shared IMR configuration is designed to measure interference for both the first and second CMR configurations, allowing one interference measurement resource to perform multiple functions that would traditionally require separate dedicated resources
2Measurement precision
If multiple separate IMR configurations are provided for each CMR configuration, then interference measurement accuracy is improved, but latency in SINR reporting increases
Solution Approach 1:
The patent combines multiple interference measurement processes into a single unified process by sharing the IMR configuration. This merging reduces the time required to configure and execute separate interference measurements for each CMR configuration, thereby reducing latency in SINR reporting while maintaining measurement accuracy through the shared interference measurement resource
3Manufacturing precision
If separate IMR configurations are configured for each CMR configuration, then configuration precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the configuration management of multiple IMR configurations into a single shared IMR configuration. This reduces the complexity of configuration management in the terminal device while maintaining precise configuration through the unified IMR setup that serves multiple CMR configurations, thereby reducing device complexity without sacrificing configuration precision

AI summary
The present disclosure provides an operation method of a terminal and a base station in a wireless communication system, and a device supporting same. According to an embodiment applicable to the present disclosure, on the basis of an assumption that two or more channel measurement resource (CMR) configurations having the same quasi co located (QCL) source in terms of a related spatial parameter from among a plurality of CMR configurations configured for the terminal share the same interference measurement resource (IMR) configuration, the terminal may calculate a signal to interference noise ratio (SINR) and report the calculated SINR to the base station.
