Receiver Assisted Sidelink Resource Allocation Adaptive Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing sidelink resources for device-to-device (D2D) communications, particularly in reducing power consumption and improving resource selection accuracy without relying on continuous resource monitoring.
Innovation Solution
A method where a user equipment (UE) can request a resource report from a nearby UE, which monitors sidelink resources and generates a report indicating available and reserved resources based on signal-to-interference ratio (SIR) thresholds, allowing the requesting UE to select resources with minimal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous resource monitoring is performed to ensure reliable sidelink communication, then resource selection accuracy is improved, but power consumption increases
Solution Approach 1:
The receiving UE performs resource monitoring and generates resource availability reports in advance before the transmitting UE needs to select resources. This preliminary action allows the transmitting UE to obtain pre-analyzed resource availability information without performing continuous monitoring itself, thereby reducing its power consumption while maintaining accurate resource selection capability.
Solution Approach 2:
The receiving UE acts as an intermediary that performs resource monitoring and analysis on behalf of the transmitting UE. It generates resource availability reports that serve as intermediate information products, allowing the transmitting UE to make informed resource selections without directly performing continuous monitoring, thus resolving the contradiction between monitoring accuracy and power consumption.
2Use of energy by moving object
If resource monitoring is minimized to reduce power consumption, then energy efficiency is improved, but resource selection accuracy deteriorates
Solution Approach 1:
The receiving UE serves as an intermediary monitoring entity that performs resource availability analysis and generates detailed reports. This allows the transmitting UE to minimize its own monitoring activities (reducing power consumption) while still obtaining accurate resource availability information through the intermediary's comprehensive monitoring and analysis.
Solution Approach 2:
The receiving UE performs self-service by proactively monitoring resources and generating availability reports for its own use and for assisting transmitting UEs. This self-initiated monitoring approach allows the system to maintain accurate resource selection capability without requiring continuous monitoring from all UEs, thereby reducing overall power consumption while preserving measurement precision where needed.

AI summary
Aspects of the disclosure relate to transmitting, from a first user equipment (UE) to a second UE, a resource report indicative of an availability of a set of resources among a sidelink resource pool based on a measurement of interference in the set of resources. The resource report includes resource availability information indicating that a reserved set of resources reserved for a third UE is available based on an interference parameter associated at least in part with the second UE or the third UE. Other aspects, and features are also claimed and described.
