Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sidelink positioning configuration is implemented, then positioning functionality is improved, but system complexity increases
Solution Approach 1:
The patent segments the sidelink positioning configuration into separate system information blocks (SIBs) - specifically SIB12 for general sidelink configuration and dedicated SIBs for positioning-specific parameters. This segmentation allows the positioning functionality to be added without overwhelming complexity in the entire system configuration, enabling flexible deployment and management of positioning resources.
Solution Approach 2:
The patent introduces network entities (such as gNodeBs or eNodeBs) as intermediaries between user equipments (UEs) and the core network for managing sidelink positioning. These network entities act as mediators that handle the complex configuration, resource allocation, and failure management tasks, reducing the complexity burden on individual UEs while enabling advanced positioning functionality.
2Reliability
If comprehensive sidelink positioning configuration is provided, then positioning reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent implements preliminary configuration of sidelink positioning parameters through system information blocks that are broadcast before actual positioning sessions commence. Configuration parameters such as resource pools, reference signals, and measurement settings are pre-established, allowing UEs to prepare their positioning capabilities in advance. This preliminary action ensures reliability by ensuring all necessary parameters are available before needed, while managing signaling overhead by batching configuration information rather than transmitting it continuously.
Solution Approach 2:
The patent introduces dynamic resource allocation mechanisms where the network can allocate sidelink resources for positioning based on current conditions and requests from UEs. The configuration parameters can be updated dynamically through reconfiguration signaling, allowing the system to adapt to changing requirements. This dynamic approach ensures positioning reliability by optimizing resources in real-time while managing overhead through targeted updates rather than continuous broadcasting of all parameters.
3Reliability
If failure handling mechanism is added, then system robustness is improved, but procedure complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where UEs report the status of sidelink positioning configuration and resource utilization to network entities. Failure conditions are detected through these feedback loops, and the network can respond with corrective actions such as reconfiguration or resource reallocation. This feedback approach improves system robustness by enabling continuous monitoring and adjustment, while managing procedure complexity through standardized feedback protocols that automate the failure detection and recovery processes.
Data Source
AI summary
Apparatus, methods, and computer program products for providing sidelink UE information are provided. An example method may include receiving at least one system information block (SIB) from a network entity, the at least one SIB including a sidelink data configuration associated with a data transmission and a sidelink positioning configuration associated with a positioning session. The example method may further include transmitting sidelink UE information to the network entity, the sidelink UE information including an indication of at least one of: a failure associated with the sidelink positioning configuration, a request for transmission (Tx) sidelink resources for the positioning session, or a list of reception (Rx) sidelink resources for the positioning session.
