Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In UE-to-UE relay scenarios, determining radio bearer configuration to ensure consistent and high-quality communication between source, relay, and target UEs is challenging due to the complexity of multiple communication paths and varying quality of service requirements.
Innovation Solution
A method for radio bearer configuration involving the exchange of configuration information and quality of service parameters between UEs and network devices to establish associated channels and bearers, ensuring end-to-end communication quality by aligning QoS profiles and identifiers, thereby facilitating data transmission through relay UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay UE is introduced to enhance coverage or capacity, then communication coverage and capacity are improved, but the complexity of radio bearer configuration increases
Solution Approach 1:
The patent segments the radio bearer configuration into two independent parts: first configuration information for the first link (source UE to relay UE) and second configuration information for the second link (relay UE to target UE). This segmentation allows each link to be configured independently while maintaining overall system functionality, thereby reducing configuration complexity despite the introduction of relay UE for enhanced coverage.
Solution Approach 2:
The patent introduces association information as an intermediary element that links the first configuration information and second configuration information. This association information acts as a mediator between the two configuration sets, enabling the relay UE to properly associate and forward data between the source UE and target UE while simplifying the configuration process through a clear linking mechanism.
2Reliability
If multiple communication paths are established for relay communication, then communication capacity and reliability are improved, but the difficulty of determining consistent radio bearer configuration increases
Solution Approach 1:
The patent segments the configuration determination process into separate steps for the first link and second link, each with its own configuration information. This segmentation makes it easier to determine and measure the configuration parameters for each link independently, while the association information ensures consistency across the entire relay communication path, thereby maintaining reliability without increasing determination difficulty.
Solution Approach 2:
The patent implements a feedback mechanism where the relay UE receives first configuration information from the source UE and second configuration information from the target UE, then uses association information to align and verify the configurations. This feedback loop ensures consistent radio bearer configuration across multiple communication paths while simplifying the determination process through structured information exchange and verification.
3Manufacturing precision
If QoS parameters are aligned across multiple links, then communication quality is improved, but the complexity of configuration information exchange increases
Solution Approach 1:
The patent uses association information as an intermediary that links the QoS parameters between the first link and second link configurations. This intermediary mechanism enables precise alignment of QoS parameters across multiple links while simplifying the exchange process by providing a clear mapping relationship between the configuration information sets, thereby achieving high precision without excessive complexity.
Solution Approach 2:
The patent applies parameter changes by transforming QoS parameters into a standardized format through the association information mechanism. This allows different QoS parameters from the first link and second link to be consistently aligned and compared, improving communication quality while reducing the complexity of parameter exchange through standardization and structured transformation.
