UE-UE Scheduling for V2X Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems face challenges in performing UE-UE scheduling effectively, which affects the reliability of vehicle-to-everything communication.
Innovation Solution
The proposed solution involves an apparatus and method for discontinuous reception capable of performing UE-UE scheduling in V2X communication, allowing one user equipment (UE) to schedule resource allocation for another UE, while considering the independent status of both UEs, including synchronization, resource allocation mode, coverage, buffer, transmit, and receive pool statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource allocation is managed by network side only, then network control is simplified, but UE-UE scheduling capability and communication reliability are insufficient
Solution Approach 1:
The patent introduces a multi-layer scheduling architecture where network side acts as primary mediator for resource allocation, while UE entities act as secondary mediators for local resource coordination. This intermediary structure enables distributed scheduling decisions that improve communication reliability without requiring complete network control, thus balancing reliability enhancement with system complexity management.
Solution Approach 2:
The scheduling function is segmented into multiple independent entities: network side scheduler, UE-level schedulers, and resource allocation modules. This segmentation allows each entity to operate autonomously within its scope, improving overall system reliability through distributed decision-making while maintaining manageable complexity through clear functional boundaries.
2Adaptability or versatility
If UE-UE scheduling is implemented, then scheduling flexibility and reliability improve, but system complexity and coordination overhead increase
Solution Approach 1:
The patent implements dynamic scheduling where UE entities can adaptively adjust resource allocation based on real-time communication conditions, buffer status, and channel quality. This dynamic approach enhances scheduling flexibility and adaptability while the modular architecture keeps coordination complexity manageable through localized decision-making at each UE entity.
Solution Approach 2:
Each UE entity implements local scheduling optimization based on its specific communication context, buffer status, and channel conditions rather than centralized uniform scheduling. This local quality approach allows flexible adaptation to local conditions while reducing overall system complexity by distributing intelligence to where it is most needed.
3Measurement precision
If independent UE status is considered in scheduling, then scheduling accuracy and reliability improve, but information processing complexity increases
Solution Approach 1:
The patent implements preliminary status reporting where UEs proactively provide buffer status, channel quality, and synchronization information to scheduling entities before resource allocation decisions are made. This preliminary action enables accurate scheduling decisions based on complete information while reducing processing complexity by organizing data collection and preparation in advance rather than during critical scheduling moments.
