Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face duplex mode conflicts among control resource sets (CORESETs) and search space (SS) sets, leading to degraded communications and resource wastage due to unresolved duplex mode conflicts.
Innovation Solution
A method and apparatus for determining duplex mode conflicts among CORESETs and SS sets, with conflict rules used to select an optimal duplex mode for communication, such as prioritizing based on CORESET or SS set identifiers, types, and aggregation levels, to resolve conflicts and improve communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CORESETs and SS sets are configured with different duplex modes, then communication flexibility is improved, but resource wastage and communication degradation occur due to unresolved conflicts
Solution Approach 1:
The system enables self-service by allowing the UE to autonomously determine and resolve duplex mode conflicts using pre-configured conflict resolution rules. The UE independently identifies conflicts among CORESETs and SS sets, applies appropriate resolution rules based on their identifiers and types, and selects the final duplex mode without requiring additional network intervention, thus preventing resource wastage while maintaining configuration flexibility
Solution Approach 2:
The invention changes the parameter of duplex mode selection by introducing conflict resolution rules that prioritize based on CORESET/SS set identifiers and types. When conflicts are detected, the system transforms the ambiguous state into a deterministic decision by applying parameter-based prioritization, resolving the contradiction between flexible configuration and resource efficiency
2Device complexity
If duplex mode conflicts are left unresolved, then system complexity is reduced, but communication quality degrades and time is wasted
Solution Approach 1:
The system applies preliminary action by pre-configuring conflict resolution rules that define prioritization criteria for CORESETs and SS sets. These rules are established in advance, enabling the UE to quickly resolve conflicts without complex real-time negotiations, thus reducing communication delay while maintaining manageable system complexity through standardized resolution procedures
Solution Approach 2:
The invention introduces dynamics by enabling adaptive duplex mode selection that responds to detected conflicts. The system dynamically adjusts the duplex mode based on the specific conflict scenario and applicable resolution rules, allowing flexible adaptation without permanent complexity increases, as the complexity is only activated when conflicts actually occur

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that there is a duplex mode conflict among control resource sets (CORESETs), among search space (SS) sets, or among one or more CORESETs and one or more SS sets, select a duplex mode based at least in part on one or more conflict rules after determining that there is a duplex mode conflict, and communicate with a base station using the duplex mode. Numerous other aspects are provided.
