UE Resource Conflict Detection and Indication in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resource reservations across user equipment (UEs), leading to potential conflicts that can result in transmission failures and resource inefficiencies.
Innovation Solution
A method for wireless communication where a first UE receives a resource reservation from a second UE and transmits an indication of a conflict if at least one resource is already reserved, including identification of the conflicting resource, reservation, or UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource reservations are managed without conflict indication mechanisms, then device complexity is reduced, but transmission reliability deteriorates due to undetected resource conflicts
Solution Approach 1:
The system performs preliminary detection of resource conflicts before transmission occurs. UEs monitor reserved resources and identify conflicts in advance, allowing them to notify other UEs before transmission failures happen. This preliminary action prevents the harmful effect of undetected conflicts while maintaining relatively simple device architecture.
Solution Approach 2:
The patent implements a feedback mechanism where UEs transmit conflict indication messages to notify other UEs about resource conflicts. This feedback loop allows the network to dynamically adjust resource allocations and avoid conflicts, improving transmission reliability without requiring complex centralized control.
2Reliability
If comprehensive resource conflict detection is implemented, then transmission reliability improves, but information overhead increases due to conflict indication messages
Solution Approach 1:
The conflict indication message extracts only the essential information needed to resolve conflicts - specifically, the resource allocation parameters and resource block indices where conflicts occur. By extracting only this critical information rather than transmitting complete resource reservation details, the system maintains high reliability while minimizing information overhead.
Solution Approach 2:
The system applies partial action by sending conflict indication messages only when actual conflicts are detected, rather than continuously transmitting resource status information. This selective approach ensures reliability for conflicted resources while avoiding unnecessary information overhead for non-conflicted resources.
3Productivity
If real-time resource conflict notification is implemented, then resource utilization efficiency improves, but processing speed requirements increase
Solution Approach 1:
The conflict detection and notification process is segmented into distinct phases: resource monitoring, conflict detection, conflict indication message transmission, and resource reallocation. This segmentation allows each component to be optimized independently, improving overall resource utilization efficiency without requiring excessively high processing speeds across the entire system.
Solution Approach 2:
The system employs periodic resource monitoring and conflict detection rather than continuous real-time analysis. UEs check for conflicts at defined intervals and trigger notification mechanisms when conflicts are detected, which improves resource utilization efficiency while reducing the instantaneous processing speed requirements compared to continuous monitoring approaches.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a resource reservation that indicates a reservation for one or more resources; and transmit an indication that at least one resource of the one or more resources is in conflict with an additional resource reservation, the indication including one or more of an identification of the at least one resource, an identification of the resource reservation, or an identification of the second UE. Numerous other aspects are provided.
