Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoS parameters are managed for relay-assisted positioning measurements, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments QoS parameter management into separate configurations for different wireless links (first link between relay UE and network entity, second link between relay UE and remote UE). Each link has its own QoS parameters (first QoS parameters and second QoS parameters respectively), allowing independent optimization without increasing overall system complexity.
Solution Approach 2:
The patent implements dynamic QoS parameter adjustment by configuring different time periods for first and second QoS parameters. The relay UE can adaptively adjust positioning measurement reporting based on varying QoS requirements and channel conditions, improving positioning accuracy while maintaining manageable system complexity through flexible configuration.
2Measurement precision
If positioning measurements are reported frequently to improve accuracy, then positioning accuracy is improved, but network signaling overhead increases
Solution Approach 1:
The patent implements periodic positioning measurement reporting with configurable time periods for both first QoS parameters (relay UE to network entity) and second QoS parameters (relay UE to remote UE). This periodic action allows accurate positioning information to be transmitted at optimized intervals, improving positioning accuracy while controlling signaling overhead through configurable reporting periods.
Solution Approach 2:
The patent enables dynamic adjustment of reporting frequency through QoS parameter configuration. The network entity can configure different time periods and QoS parameters adaptively based on positioning accuracy requirements and network conditions, allowing frequent reporting when needed while reducing overhead during normal operation.
3Productivity
If QoS parameters are optimized for relay-assisted positioning, then positioning efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides QoS parameter management into separate configurations for different wireless links at the relay UE. The relay UE handles first QoS parameters for the link to the network entity and second QoS parameters for the link to the remote UE independently, which improves positioning efficiency through link-specific optimization while managing device complexity through modular configuration handling.
Solution Approach 2:
The relay UE is configured to autonomously manage QoS parameters and positioning measurement reporting based on received configurations from the network entity. This self-service capability improves positioning efficiency by enabling automatic QoS adjustment and reporting without continuous network intervention, while keeping device complexity manageable through standardized configuration procedures.

AI summary
A relay user equipment (UE) may be configured to receive an indication of one or more of at least one first quality of service (QOS) parameter for a first wireless link or at least one second QoS parameter for a second wireless link. The first wireless link may be associated with the relay UE and a network entity. The second wireless link may be associated with the relay UE and at least one remote UE. The at least one first QoS parameter and the at least one second QoS parameter may be associated with a time period. The relay UE may be configured to transmit a report of at least one positioning measurement within the time period based on one or more of the at least one first Qos parameter or the at least one second QoS parameter.
