Channel State Information Report Calculation Using Resource Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently calculating channel state information reports, particularly when multiple beams are transmitted concurrently from different transmission reception points, leading to increased signaling overhead and complexity in determining which channel state information reference signal resources can be transmitted simultaneously.
Innovation Solution
The method involves receiving configuration information for multiple channel state information reference signal resources, determining two channel state information reference signal resources from different transmission reception points or panels that can be used for calculating a channel state information report, and transmitting this report, utilizing quasi co-location information and sets of mutually-exclusive or co-transmission sets to simplify the process.

Engineering Contradiction Analysis
1Productivity
If multiple beams are transmitted concurrently from different transmission reception points, then the system capacity and connectivity are improved, but the signaling overhead and complexity in determining channel state information reference signal resources increase
Solution Approach 1:
The patent segments the channel state information reference signal resources into distinct sets based on transmission reception points. By dividing the resources into mutually exclusive sets and co-transmission sets, the system can efficiently determine which resources can be transmitted concurrently without requiring complex signaling across all possible resource combinations, thus reducing overall signaling complexity while maintaining multi-beam capability.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the remote unit with information about mutually-exclusive sets and co-transmission sets of channel state information reference signal resources. This advance preparation allows the remote unit to automatically determine valid resource combinations for concurrent transmission without requiring real-time complex signaling, thereby reducing signaling overhead while enabling multiple concurrent beams.
2Measurement precision
If multiple channel state information reference signal resources are configured, then the accuracy of channel state information reporting is improved, but the complexity of determining which resources can be transmitted simultaneously increases
Solution Approach 1:
The patent segments the channel state information reference signal resources into mutually-exclusive sets and co-transmission sets. This segmentation provides a structured framework that simplifies the determination of which resources can be transmitted simultaneously. By organizing resources in this manner, the system maintains accurate channel state information measurement across multiple resources while reducing the complexity of selecting valid combinations for concurrent transmission.
Solution Approach 2:
The patent introduces mutually-exclusive sets and co-transmission sets as intermediary structures that mediate between the need for high measurement precision and the need for simple resource selection. These intermediary sets act as rules or guidelines that help the remote unit determine valid resource combinations without requiring complex analysis of all possible resource interactions, thus maintaining accuracy while simplifying the selection process.
