Sidelink Reception Timing Configuration for Geographic Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in configuring reception timing for sidelink signals across different geographic regions without altering the cyclic prefix (CP) length, which is affected by propagation delay, leading to increased overhead.
Innovation Solution
A method for a user equipment (UE) to receive sidelink signals by configuring reception timing based on synchronization signals specific to each geographic region, allowing for transmission and reception without changing the CP length, by using time-divided resource regions and puncturing or rate-matching symbols in overlapping regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cyclic prefix (CP) length is increased to accommodate propagation delay in different geographic regions, then reliable sidelink signal reception is achieved, but system overhead increases
Solution Approach 1:
The patent divides the service area into multiple geographic regions, each with its own reception timing configuration. Instead of using a single extended CP for all regions, the system segments the coverage area and applies region-specific timing adjustments, thereby maintaining reliability without universally increasing overhead.
Solution Approach 2:
The patent implements local quality by configuring reception timing specific to each geographic region based on local propagation delay characteristics. Each region uses a reception timing tailored to its specific conditions rather than a uniform system-wide configuration, optimizing performance locally without affecting other regions.
2Device complexity
If reception timing is configured uniformly across all geographic regions, then system complexity is reduced, but propagation delay variations cause reception failures in certain regions
Solution Approach 1:
The patent applies local quality by configuring reception timing specific to each geographic region based on local propagation delay characteristics. Each region uses a reception timing tailored to its specific conditions rather than a uniform system-wide configuration, optimizing performance locally without affecting other regions.
Solution Approach 2:
The patent changes the reception timing parameter according to geographic region and propagation delay conditions. By adjusting this parameter locally rather than keeping it fixed uniformly, the system achieves reliable reception across diverse geographic conditions without excessive complexity.
3Ease of operation
If a single reception timing is used for all geographic regions, then configuration simplicity is maintained, but overlapping resource regions cause interference in boundary areas
Solution Approach 1:
The patent applies local quality by configuring reception timing specific to each geographic region based on local propagation delay characteristics. Each region uses a reception timing tailored to its specific conditions rather than a uniform system-wide configuration, optimizing performance locally without affecting other regions.
