Solution Overview
Problem
The assessment of radio link quality in wireless communication systems is a key issue, particularly in diverse application scenarios, and existing methods do not efficiently adapt to changes in environment and scenario requirements, leading to potential inefficiencies and increased hardware complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing methods are used for radio link quality assessment, then the system can maintain basic functionality, but the system cannot efficiently adapt to changes in environment and scenario requirements, leading to increased hardware complexity
Solution Approach 1:
The patent implements dynamic adaptation by allowing the system to switch between different RS resource pools based on environmental conditions and scenario requirements. The network can dynamically configure and switch between first RS resource pools (for initial assessment) and second RS resource pools (for adapted assessment), enabling the system to respond to changing conditions without requiring multiple fixed hardware configurations for different scenarios.
Solution Approach 2:
The patent creates a universal radio link quality assessment mechanism that can handle multiple application scenarios (uplink, downlink, sidelink, vehicle networking) through a unified framework. The same assessment architecture supports different RS resource pools and assessment methods, allowing one hardware system to perform multiple functions across diverse scenarios without requiring scenario-specific hardware modifications.
2Speed
If existing methods are used for radio link quality assessment, then the system can operate with current hardware, but the adjustment speed of RS resources is slow, reducing system efficiency
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple RS resource pools (first and second pools) with different characteristics and purposes. The network can pre-prepare appropriate resource pools for different scenarios, so when environmental changes occur, the system can quickly switch to the pre-configured appropriate pool rather than creating resources from scratch, thereby increasing adjustment speed while maintaining system efficiency.
3Reliability
If scenario-specific solutions are implemented for different application scenarios, then each scenario can be optimized, but hardware complexity and costs increase
Solution Approach 1:
The patent implements a universal radio link quality assessment framework that serves multiple application scenarios (uplink, downlink, sidelink, vehicle networking) through a single standardized interface. The network can configure different RS resource pools with scenario-appropriate parameters, but the underlying hardware and assessment architecture remain unified, allowing scenario-specific optimization without requiring separate hardware systems for each application.
Solution Approach 2:
The patent achieves scenario-specific optimization through parameter changes rather than structural changes. Different scenarios are supported by configuring different parameters (RS resource pool characteristics, assessment thresholds, TCI state associations) within the same hardware framework, allowing each scenario to be optimized for its specific requirements while sharing the same physical infrastructure.

AI summary
The present application discloses a method used in a node for wireless communication, and an apparatus. A first node receiving a first higher layer message set, the first higher layer message set being used to configure a first RS resource pool for a first BWP, the first RS resource pool being used for radio link quality assessment; receiving a first signaling, the protocol layer to which the first signaling belongs is a protocol layer under the RRC layer; as a response to receiving the first signal, the radio link quality of the first BWP is assessed according to the second RS resource pool. At least one RS resource of the second RS resource pool depends on the TCI state of CORESET.
