Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent understanding of the time-domain interval determining parameter K between sending and receiving devices in sidelink communication systems leads to transmission issues, affecting communication effectiveness.
Innovation Solution
A method and device for determining a time-domain resource, where the parameter K is predefined, configured, indicated by the first information, or obtained based on processing time, allowing terminal devices to accurately determine the second time-domain resource occupied by second information, thereby resolving transmission problems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the time-domain interval determining parameter K is ambiguously defined, then the system complexity is reduced, but transmission reliability deteriorates due to inconsistent understanding between sending and receiving devices
Solution Approach 1:
The patent changes the definition and determination method of parameter K from ambiguous to precise. It provides multiple specific determination methods including: K being predefined in specifications, K being configured by network side, K being indicated by first information, or K being obtained based on processing time. This parameter refinement resolves the inconsistency between sending and receiving devices while maintaining reasonable system complexity.
2Reliability
If the parameter K is precisely defined through multiple determination methods, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic determination mechanism for parameter K, where the determination method adapts to different scenarios. The receiving device can select from multiple determination methods based on actual conditions: predefined values for standard cases, network configuration for controlled environments, indication from first information for flexible scenarios, or processing time-based calculation for performance-optimized cases. This dynamic approach balances reliability improvement with device complexity management.
