Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, existing methods for configuring control resource sets (CORESETs) face challenges in efficiently managing control information transmission, particularly in scenarios requiring flexible UL/DL configuration and interference mitigation, which affects RSSI measurement accuracy and network flexibility.
Innovation Solution
The proposed solution involves configuring RSSI measurement resources (RMR) to always be downlink, with the option to override transmission direction configurations, allowing for carrier-specific and periodic RMR settings, and providing UE behavior options to handle RMR configurations, ensuring accurate RSSI measurements and network flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transmission direction configuration is overridden to prioritize downlink RMR, then RSSI measurement accuracy is improved, but network flexibility is reduced
Solution Approach 1:
The system dynamically adjusts the transmission direction of RMR based on measurement requirements. The network can flexibly configure RMR resources as downlink-only when RSSI measurement accuracy is prioritized, while maintaining the ability to switch to dynamic UL/DL configurations when network flexibility is needed, allowing adaptive response to different operational scenarios
Solution Approach 2:
The invention changes the transmission direction parameter of RMR resources from dynamic (following UL/DL configuration) to fixed downlink when measurement accuracy is required. This parameter change ensures accurate RSSI measurements by eliminating uplink transmission interference, while the network retains flexibility through separate configuration mechanisms for different RMR instances
2Productivity
If carrier-specific and periodic RMR settings are implemented, then control information transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The invention segments RMR configuration into carrier-specific and periodic components, allowing independent optimization of each aspect. Carrier-specific settings handle frequency-dependent characteristics, while periodic settings manage time-dependent patterns, reducing the complexity burden on UE by dividing the configuration into manageable, independent parameters
Solution Approach 2:
The network autonomously configures carrier-specific and periodic RMR parameters based on system requirements, reducing the burden on UE. The UE simply follows the configured patterns without needing complex decision-making logic, thereby improving transmission efficiency while keeping device complexity manageable
