Neighboring RS Resource Configuration for Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as 5G NR, face challenges in efficient beam management, particularly in identifying and reporting neighboring reference signal (RS) resources, which affects communication quality and latency.
Innovation Solution
The method involves configuring neighboring RS resources for user equipment (UE) and network nodes, allowing the UE to identify and report not only the strongest beam but also neighboring beams associated with a target beam, without increasing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE reports only the strongest beam, then the signaling overhead is reduced, but the beam management accuracy and neighboring beam identification is compromised
Solution Approach 1:
The patent segments the beam reporting process into two parts: (1) the UE identifies and reports the strongest beam (target RS resource), and (2) the UE identifies and reports neighboring beams based on pre-configured neighboring RS resource relationships. This segmentation allows the system to obtain both the strongest beam and neighboring beam information without requiring the UE to report all measured beams, thus reducing signaling overhead while maintaining beam management accuracy.
Solution Approach 2:
The network node performs preliminary action by configuring and providing the UE with neighboring RS resource configuration information before the actual beam measurement and reporting process. This pre-configuration includes information about which RS resources are considered neighbors of each other, allowing the UE to efficiently identify and report only the relevant neighboring beams without needing to measure and report all possible beams, thereby reducing signaling overhead.
2Measurement precision
If the UE measures and reports all reference signal resources, then the beam management precision is improved, but the time consumption and processing complexity increase
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different beam resources. Instead of uniformly measuring and reporting all RS resources, the system focuses measurement and reporting efforts on the strongest beam and its neighboring beams only. The neighboring RS resource configuration guides the UE to measure and report only the locally relevant beams (strongest and immediate neighbors) rather than all possible beams, thus improving measurement precision for critical beams while reducing overall processing time.
Solution Approach 2:
The network node performs preliminary action by pre-configuring the UE with neighboring RS resource information before the measurement process. This pre-configuration includes the relationships between different RS resources, allowing the UE to quickly identify which resources need to be measured and reported. This eliminates the need for the UE to systematically measure and evaluate all possible beam resources, significantly reducing measurement time while maintaining precision for the most important beams.
3Reliability
If the network configures detailed neighboring RS resource information, then the beam management accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies universality by designing the neighboring RS resource configuration to serve multiple functions simultaneously. The configuration not only identifies which RS resources are neighbors but also implicitly defines the spatial relationships and measurement requirements. This multi-functional configuration approach allows the network to provide comprehensive beam management information without proportionally increasing signaling overhead, as the same configuration data supports both neighbor identification and spatial relationship understanding.
Solution Approach 2:
The patent applies partial action by configuring only the necessary neighboring RS resource information that the UE needs for effective beam management. Rather than providing exhaustive details about all possible beam relationships, the network configures only the neighboring relationships that are most relevant for beam selection and switching. This partial configuration approach maintains beam management reliability by providing sufficient information for accurate beam identification while minimizing the complexity and overhead of the configuration process.
Data Source
AI summary
The UE may receive a neighboring RS resource configuration associated with an RS resource set and identify one or more neighboring RS resources associated with at least one target RS resource based on the neighboring RS resource configuration. The method of wireless communication may improve beam management through enabling the UE to report not just measurements of a strongest beam, but also enabling the UE to identify one or more neighboring beams associated with a target beam as a part of beam management, without increasing the signaling overhead to indicate the neighboring beams.
