Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing sidelink-based resource configuration manner is used, then resource allocation can be performed, but the configuration manner is monotonous and lacks flexibility
Solution Approach 1:
The patent implements dynamic resource scheduling where the scheduling terminal device can flexibly select between different resource allocation modes (mode 1, mode 2, mode 2d) based on real-time communication conditions, terminal capabilities, and network state, transforming the static resource configuration into a dynamic adaptive system that enhances versatility without proportionally increasing complexity
Solution Approach 2:
The scheduling terminal device is designed with multi-functional capability to support multiple resource allocation modes (mode 1 for network-scheduled, mode 2 for autonomous selection, mode 2d for group-based scheduling), allowing a single device to perform diverse scheduling functions that were previously distributed across different specialized mechanisms, thereby improving adaptability while managing complexity through consolidation
2Productivity
If mode 2(d) resource scheduling is implemented, then resource allocation efficiency is improved, but the specific procedure is unclear when combined with other modes
Solution Approach 1:
The patent segments the resource scheduling procedure into distinct phases: resource pool configuration phase, mode selection phase, resource allocation phase, and resource usage phase. Each phase has clearly defined inputs, processes, and outputs, making the complex mode 2d scheduling procedure easier to understand and implement while maintaining high allocation efficiency through structured decision-making
3Adaptability or versatility
If multiple resource allocation modes are supported, then adaptability is improved, but system complexity increases
Solution Approach 1:
The scheduling terminal device acts as an intermediary that manages the complexity of multiple resource allocation modes. It receives configuration information from the network, determines the appropriate mode based on predefined criteria and current conditions, and coordinates resource allocation among group members. This intermediary role centralizes the complexity management, allowing multiple modes to coexist without proportionally increasing overall system complexity

AI summary
This application discloses a resource scheduling method, an apparatus, and a system, to provide a resource scheduling manner based on sidelink transmission. The method includes: A scheduling terminal device determines a resource for a sending terminal device to perform sidelink (sidelink) transmission; and the scheduling terminal device sends a first message to the sending terminal device, where the first message is used to indicate the transmission resource, where the resource is specifically used to perform a part or all of the following: transmission of data information, transmission of control information, and transmission of feedback information. A manner in which the scheduling terminal device determines, for the sending terminal device, the transmission resource for data transmission is provided, and is an enriched and complete sidelink-based resource configuration manner.
