Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless device continuously monitors and evaluates sidelink resources to ensure reliable communication, then communication reliability is improved, but device complexity and processing overhead increase
Solution Approach 1:
The network configures the wireless device with a set of pre-selected sidelink resources in advance, before the device needs to use them for communication. This preliminary configuration allows the device to skip continuous monitoring and evaluation, reducing processing overhead while maintaining reliable communication through pre-validated resource assignments
Solution Approach 2:
The wireless device autonomously selects sidelink resources from a pre-configured set based on simple criteria (such as availability checks), rather than requiring continuous network coordination or complex evaluation algorithms. This self-service approach reduces device complexity while maintaining communication reliability
2Manufacturing precision
If a wireless device performs comprehensive resource evaluation for sidelink transmission, then resource allocation quality is improved, but processing time and energy consumption increase
Solution Approach 1:
The wireless device performs a simplified, partial evaluation of sidelink resources by checking only critical parameters (such as resource availability and basic interference conditions) from a pre-configured set, rather than conducting comprehensive evaluations of all possible resources. This partial action approach achieves sufficient resource allocation quality while significantly reducing processing time
Solution Approach 2:
The network configures specific parameters and criteria that guide the wireless device's resource selection process, allowing the device to focus evaluation efforts on the most relevant parameters. This parameter-driven approach ensures adequate resource allocation quality without requiring exhaustive evaluation of all resource characteristics
3Adaptability or versatility
If the network provides detailed configuration for sidelink resource selection, then communication adaptability is improved, but signaling overhead and network complexity increase
Solution Approach 1:
The network divides sidelink resource configuration into multiple levels: core parameters are configured by the network, while secondary parameters are determined autonomously by the wireless device based on pre-configured rules. This segmentation reduces network signaling overhead while maintaining communication adaptability across different scenarios
Solution Approach 2:
The network provides a universal set of pre-configured sidelink resources and selection criteria that can be applied across multiple wireless devices and different communication scenarios. This universal configuration approach reduces network complexity by avoiding device-specific custom configurations while maintaining adaptability through parameter adjustments

AI summary
A wireless device selects a first resource, from a set of resources in a sidelink resource pool, for a sidelink transmission. The wireless device transmits the sidelink transmission via a second resource, wherein the second resource is selected: from remaining resources, other than the first resource, of the set; and based on re-evaluation of the first resources being skipped.
