Sidelink Resource Selection via Conditional Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in efficiently managing sidelink resources, leading to collisions and decreased throughput due to adherence to non-preferred resources, which can result in interrupted high-priority communications and failure to meet quality of service requirements.
Innovation Solution
A method where user equipment (UE) exchanges coordination information about preferred and non-preferred sidelink resources, allowing for conditional reception and transmission based on priority and packet delay budgets, enabling selection of non-preferred resources for high-priority communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs adhere to non-preferred sidelink resources to avoid collisions, then resource collision is reduced, but high-priority communications are interrupted and throughput decreases
Solution Approach 1:
The patent implements dynamic resource selection by allowing UEs to switch between preferred and non-preferred resources based on communication priority. High-priority communications can dynamically override the non-preferred resource restrictions, creating a flexible system that adapts to varying QoS requirements while maintaining collision avoidance for normal traffic.
Solution Approach 2:
The system changes the resource selection parameter based on priority levels. For high-priority communications, the resource preference parameter is inverted or overridden, allowing transmission on non-preferred resources. This parameter change enables the system to optimize throughput for critical communications without compromising the collision avoidance mechanism for standard traffic.
2Productivity
If UEs strictly follow coordination information indicating non-preferred resources, then resource allocation efficiency is improved, but quality of service requirements cannot be met for high-priority communications
Solution Approach 1:
The patent segments the resource selection process into different priority levels. Normal communications follow the coordination information and use preferred resources, while high-priority communications are segmented into a separate category that can override the coordination information. This segmentation allows the system to maintain overall allocation efficiency while ensuring QoS for critical traffic.
Solution Approach 2:
The priority level acts as an intermediary between the coordination information and the actual resource selection. When high-priority communication is detected, the priority level mediates by allowing the UE to ignore the non-preferred resource indication and select appropriate resources that meet QoS requirements, thus bridging the conflict between efficiency and reliability.

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, coordination information indicating a non-preferred sidelink resource. The UE may transmit a communication on the non-preferred sidelink resource when a condition associated with the communication is satisfied. Numerous other aspects are described.
