Uplink Information Conflict Resolution via Spatial Relation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in managing conflicts between multiple uplink information channels in a multi-TRP scenario, where conflicts arise due to overlapping time-frequency resources, leading to inefficiencies in transmission reliability and throughput.
Innovation Solution
The method involves determining a target spatial relation for conflicting uplink information, configured or indicated by the network device, and sending the information based on this relation to avoid conflicts, using techniques such as multiplexing, discarding, or switching to resolve overlapping issues.

Engineering Contradiction Analysis
1Reliability
If multiple uplink information channels are transmitted simultaneously in a multi-TRP scenario, then transmission reliability and throughput performance are improved, but conflicts arise due to overlapping time-frequency resources
Solution Approach 1:
The patent segments uplink information into different types (first type and second type) and applies different conflict resolution strategies to each type. First type information is discarded when conflicts occur, while second type information undergoes multiplexing processing. This segmentation allows the system to maintain transmission reliability for critical information while managing resource conflicts effectively.
Solution Approach 2:
The patent merges multiple conflicting uplink information channels by multiplexing second type information onto a single physical uplink shared channel (PUSCH). This combining approach resolves time-frequency resource conflicts while preserving the content of multiple information sources, thereby maintaining throughput performance without generating harmful interference.
2Duration of action of stationary object
If multiplexing processing is applied to resolve channel conflicts, then transmission continuity is maintained, but processing complexity increases
Solution Approach 1:
The patent applies different processing qualities to different types of uplink information based on their importance. First type information receives simple discard processing when conflicts occur, while second type information receives complex multiplexing processing. This localized quality approach ensures transmission continuity for critical information while minimizing unnecessary processing complexity for less critical information.
3Device complexity
If discarding processing is used to resolve conflicts, then processing complexity is reduced, but information loss occurs
Solution Approach 1:
The patent implements dynamic conflict resolution by adapting the processing strategy to the specific type of uplink information involved. The system dynamically selects between discard and multiplexing approaches based on information classification, ensuring that discarding is applied only when appropriate (first type information) to minimize information loss while keeping processing complexity manageable.
