Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flexible resource allocation is implemented to improve spectral efficiency and adaptability, then resource utilization efficiency is improved, but resource direction ambiguity and communication reliability deteriorate
Solution Approach 1:
The network node pre-configures a set of resolution rules for handling flexible resources before actual resource allocation occurs. These rules are established in advance through RRC signaling, enabling the repeater to autonomously resolve resource direction (uplink or downlink) without real-time network intervention, thus maintaining both flexibility and reliability
Solution Approach 2:
The repeater is empowered to autonomously resolve the direction of flexible resources by applying pre-configured rules based on local observations of preceding or succeeding resource directions. This self-service mechanism eliminates the need for continuous network control signaling, improving both resource utilization efficiency and reducing direction ambiguity
2Adaptability or versatility
If network-controlled repeaters are deployed to enhance coverage and capacity, then network coverage and communication capacity are improved, but system complexity and configuration difficulty increase
Solution Approach 1:
The repeater autonomously determines the direction of flexible resources by observing the directions of preceding or succeeding resources and applying pre-configured resolution rules. This self-service capability eliminates the need for complex real-time control signaling between the network and repeater, significantly reducing system configuration complexity while maintaining enhanced coverage and capacity
Solution Approach 2:
The repeater uses feedback from the resource direction configuration to autonomously resolve flexible resource directions. By monitoring the directions of neighboring resources and applying resolution rules, the repeater creates a self-regulating system that reduces configuration complexity while maintaining adaptability

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information identifying a resource as a flexibly assigned resource, wherein the flexibly assigned resource is usable for an uplink or a downlink. The network node may resolve the resource based at least in part on a direction of one or more other resources preceding or succeeding the resource. Numerous other aspects are described.
