Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resource configurations are used for different signals and channels, then network functionality and service coverage are improved, but time domain resource conflicts occur and energy consumption increases
Solution Approach 1:
The patent applies preliminary action by establishing a priority relationship between different resource configurations before conflicts occur. The network side configures priority indicators (such as priority fields in DCI or RRC signaling) that predefine which signals/channels should take precedence when resource conflicts are detected, enabling proactive conflict resolution rather than reactive handling
Solution Approach 2:
The patent changes the parameter of resource allocation by dynamically adjusting time domain resource positions based on priority levels. When a high-priority signal conflicts with a low-priority signal, the system modifies the time domain parameters (slot offset, start symbol) of the low-priority signal to avoid conflict, thereby reducing unnecessary transmissions and saving energy
2Use of energy by stationary object
If resource configurations are dynamically adjusted for energy saving, then network energy efficiency is improved, but resource allocation complexity and signaling overhead increase
Solution Approach 1:
The patent segments resource configurations into multiple priority levels (e.g., high priority for critical control signals, low priority for data transmissions). This segmentation allows the system to apply different energy-saving strategies to different signal types independently, simplifying the overall decision-making process while maintaining energy efficiency
Solution Approach 2:
The patent implements self-service by enabling the wireless terminal to autonomously detect resource conflicts and apply priority-based resolution rules without requiring complex network-side coordination for each conflict. The terminal uses pre-configured priority information to automatically determine which signals to transmit and which to skip, reducing signaling overhead
3Reliability
If priority-based resource allocation is implemented, then resource conflict resolution is improved, but signaling overhead for conveying priority information increases
Solution Approach 1:
The patent merges priority information with existing signaling structures rather than introducing separate dedicated signaling. Priority indicators are embedded within DCI formats or RRC configuration messages that are already transmitted for resource allocation, thereby conveying priority information without significantly increasing overall signaling overhead
Solution Approach 2:
The patent creates a universal priority indication mechanism that can be applied across multiple signal types and scenarios (uplink grants, downlink assignments, random access procedures). This multi-functional priority system reduces the need for scenario-specific signaling, as the same priority indication framework serves multiple purposes

AI summary
The present application discloses a method and apparatus for a node used for wireless communication. The method comprises: a first node receiving a second information block, the second information block being used for determining a second resource configuration; receiving target signaling, the target signaling being used for scheduling a target signal on a first cell; receiving a first information block, the first information block being used for determining a first resource configuration; and sending the target signal in a target time domain resource, or forgoing sending the target signal in the target time domain resource, wherein the target time domain resource depends on the second resource configuration, whether the target signal is forgone being sent in the target time domain resource or not depends on whether a first condition is met or not, and when the first condition is met, the target signal is forgone being sent in the target time domain resource. The present application can improve the network side energy efficiency and the transmission reliability.
