Sidelink Radio Link Grouping for Low-Overhead Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods to manage multiple radio links between wireless devices, leading to unnecessary data transmissions, computation overhead, and power consumption due to separate monitoring and adaptation of each link.
Innovation Solution
A wireless device or network node receives configuration information to determine the link properties of one radio link, allowing modifications to be applied to other links with similar properties, thereby reducing unnecessary signaling and computations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate monitoring and adaptation is performed for each radio link, then link-specific optimization is achieved, but computational overhead and power consumption increase
Solution Approach 1:
The patent merges the monitoring and adaptation operations for multiple radio links by introducing a group structure. Instead of treating each link independently, links are grouped together and monitored collectively, reducing redundant computations while maintaining link-specific optimization through the group-based approach.
Solution Approach 2:
The patent implements a universal monitoring mechanism that can handle multiple radio links simultaneously. The adaptation framework is designed to be multi-functional, allowing a single monitoring and adaptation process to serve multiple links within a group, thereby reducing overall computational overhead.
2Reliability
If separate monitoring and adaptation is performed for each radio link, then link-specific optimization is achieved, but power consumption increases
Solution Approach 1:
The patent merges the monitoring and adaptation operations for multiple radio links by introducing a group structure. Instead of treating each link independently, links are grouped together and monitored collectively, reducing redundant computations while maintaining link-specific optimization through the group-based approach.
Solution Approach 2:
The patent implements periodic monitoring and adaptation actions for radio link groups rather than continuous separate monitoring for each link. This periodic approach reduces power consumption by activating monitoring only when necessary while maintaining effective link management through scheduled updates.
3Reliability
If separate monitoring and adaptation is performed for each radio link, then link-specific optimization is achieved, but unnecessary data transmissions occur
Solution Approach 1:
The patent merges the monitoring and adaptation operations for multiple radio links by introducing a group structure. Instead of treating each link independently, links are grouped together and monitored collectively, reducing redundant computations while maintaining link-specific optimization through the group-based approach.
Solution Approach 2:
The patent implements a self-service mechanism where the system automatically determines when monitoring and adaptation are needed based on group conditions. This eliminates unnecessary data transmissions by avoiding redundant monitoring when links are stable or when group-level changes are detected, while still maintaining link-specific optimization when required.
4Adaptability or versatility
If multiple radio links are managed separately, then flexible adaptation is achieved, but signaling overhead increases
Solution Approach 1:
The patent merges the management of multiple radio links by introducing a group structure. Links are grouped together and managed collectively, reducing redundant signaling while maintaining adaptation flexibility through the group-based framework that allows coordinated modifications across multiple links.
Solution Approach 2:
The patent implements a universal signaling mechanism that can handle multiple links simultaneously. The adaptation framework is designed to be multi-functional, allowing a single signaling process to affect multiple links within a group, thereby reducing overall signaling overhead while maintaining flexible adaptation.

AI summary
The present invention relates to a method, wireless device and network node for supporting efficient, fast dynamic adaptation of radio links that allow for direct communication between wireless devices. It is desired to reduce signalling overhead and computations. The method at the wireless device comprises receiving configuration-information related to the other wireless device from the other wireless device or a node; determining a link-property of a first radio link of the multiple radio links based on the configuration-information; causing a modification of a second radio link of the multiple radio links based on the determined link-property.
