Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless devices perform sidelink communications autonomously without base station coordination, then device autonomy and communication speed are improved, but resource allocation efficiency and coordination reliability deteriorate
Solution Approach 1:
The base station acts as an intermediary that coordinates sidelink resource allocations between wireless devices. The base station receives capability information from devices, determines appropriate ranging methods and parameters, and allocates radio resources (time, frequency, spatial) for sidelink communications. This mediator approach enables autonomous device operation while maintaining centralized resource management efficiency.
2Productivity
If base station coordinates all sidelink communications, then resource allocation efficiency is improved, but system complexity and coordination overhead increase
Solution Approach 1:
The coordination function is segmented between the base station and wireless devices. The base station handles high-level resource allocation and parameter determination, while wireless devices autonomously execute specific ranging procedures using allocated resources. This segmentation reduces base station processing burden and simplifies device implementation.
Solution Approach 2:
Wireless devices autonomously determine their ranging capabilities, select appropriate ranging methods from base station-provided options, and execute ranging procedures using allocated resources without continuous base station intervention. Devices self-configure their sidelink communications based on base station allocations.
3Adaptability or versatility
If devices select ranging methods autonomously, then device flexibility is improved, but measurement precision and coordination reliability deteriorate
Solution Approach 1:
The base station performs preliminary actions by determining suitable ranging methods and parameters based on device capabilities and network conditions before devices execute ranging. The base station pre-allocates resources and provides configuration parameters that ensure measurement precision while allowing devices flexibility in execution.
Solution Approach 2:
Devices provide feedback to the base station regarding their ranging capabilities and performance. The base station uses this feedback to optimize ranging method selection and parameter configuration, improving measurement precision while maintaining device autonomy in method selection.
