Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional communication structure is used, then system simplicity is maintained, but communication flexibility and efficiency are limited
Solution Approach 1:
The patent implements dynamic resource allocation where the network device can flexibly configure and reconfigure resource pools, reference signal resources, and communication parameters based on real-time network conditions and service requirements. This allows the system to adapt to different scenarios (eMBB, mMTC, URLLC) without requiring multiple fixed communication structures, thus improving flexibility while maintaining manageable complexity through centralized control.
Solution Approach 2:
The patent creates a universal communication framework that can handle multiple service types (eMBB, mMTC, URLLC) and multiple communication modes (uplink, downlink, sidelink) using a single flexible resource allocation mechanism. The same base station and user equipment can dynamically switch between different communication patterns and resource configurations, eliminating the need for separate dedicated structures for each service type.
2Productivity
If resource allocation is optimized for specific scenarios, then efficiency for those scenarios improves, but adaptability to other scenarios deteriorates
Solution Approach 1:
The system employs dynamic resource pool configuration where the network device can allocate, modify, and release resource pools based on current service demands. Different resource pools can be configured with different parameters (time, frequency, spatial resources) and activated/deactivated dynamically to optimize efficiency for the current scenario while maintaining the capability to adapt to other scenarios when needed.
Solution Approach 2:
The patent utilizes parameter-based resource configuration where resource pools are defined by configurable parameters (time resources, frequency resources, spatial resources, reference signal resources). By changing these parameters dynamically, the system can optimize resource allocation for different service scenarios without changing the underlying resource allocation mechanism, thus maintaining adaptability while achieving scenario-specific efficiency.
3Reliability
If multiple resource pools are configured for different services, then service-specific optimization is achieved, but system complexity increases
Solution Approach 1:
The patent segments communication resources into distinct resource pools (time resources, frequency resources, spatial resources, reference signal resources) that can be independently configured and managed. Each resource pool can be dedicated to specific services or scenarios, ensuring service reliability through isolated resource allocation while the modular structure keeps management complexity manageable through standardized pool definitions and centralized control.
Solution Approach 2:
The network device acts as an intermediary that centrally manages multiple resource pools, handling the complexity of resource pool configuration, activation, and coordination. This centralized mediation allows multiple service-specific resource pools to coexist without requiring complex peer-to-peer coordination between user equipments, thus achieving service reliability while containing system complexity through hierarchical control.

AI summary
A user equipment (UE) is described. The UE may comprise higher layer processing circuitry configured to receive SystemInformationBlockTypeXX (SL PRS related System Information Block) from a base station. The UE may also comprise transmission circuitry configured to perform a transmission of sidelink positioning reference signal (SL-PRS). When the UE is in-coverage for the transmission of the SL-PRS, the UE may perform a first procedure of the transmission of the SL-PRS according to SystemInformationBlockTypeXX. When out-of-coverage for the transmission of the SL-PRS, the UE may perform a second procedure of the transmission of the SL-PRS according to pre-configuration.
