Autonomous Smart Relay Partial Configuration for Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomously smart repeaters in wireless communication networks can lead to undesired end-to-end performance due to their ability to reconfigure parameters, causing interference and disrupting measurements for interference correction.
Innovation Solution
Implementing a partial configuration technique where a control entity can configure autonomously smart repeaters to disable autonomous reconfiguration in specific resources, maintain phase continuity, and adhere to quasi-colocation relations, thereby preventing interference and ensuring accurate measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomously smart repeaters reconfigure parameters autonomously, then adaptability is improved, but interference is generated and measurement accuracy deteriorates
Solution Approach 1:
The patent segments the repeater's operation into autonomous reconfiguration mode and controlled mode. The control entity receives indication information that segments resources into those where autonomous reconfiguration is allowed and those where it is restricted, enabling partial configuration rather than complete autonomy or complete control.
Solution Approach 2:
The patent applies local quality by allowing different reconfiguration behaviors in different resource segments. The control entity configures the repeater to apply autonomous reconfiguration to specific parameters in specific resources while maintaining fixed configuration in other resources, creating localized quality differences in the repeater's operation.
2Adaptability or versatility
If autonomously smart repeaters reconfigure parameters autonomously, then adaptability is improved, but harmful interference is generated
Solution Approach 1:
The patent implements preliminary anti-action by having the control entity pre-configure the repeater with restrictions on autonomous reconfiguration in specific resources. This preliminary configuration prevents the repeater from generating harmful interference in those resources by limiting its autonomous parameter changes before the interference can occur.
Solution Approach 2:
The patent uses parameter changes by modifying the repeater's operational parameters through control entity configuration. The control entity changes the repeater's behavior from fully autonomous to partially controlled by adjusting which parameters can be reconfigured autonomously and which must remain fixed in specific resources.
3Measurement precision
If control entity restricts autonomous reconfiguration, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by allowing the repeater to autonomously reconfigure parameters in resources where the control entity permits it. This reduces the burden on the control entity and network complexity by enabling the repeater to self-configure in appropriate scenarios while only requiring control entity intervention when restrictions are needed.

AI summary
Techniques for partial configuration of an autonomously smart repeater may allow a control entity (e.g., base station, UE, or cloud software/algorithm) to configure the autonomously smart repeater and thereby improve end-to-end performance for some communications. In an example, a relay device may receive, from a first entity, an indication for reconfiguring a parameter corresponding to an autonomous reconfiguration procedure of the relay device. The relay device may configure a setting of the autonomous reconfiguration procedure according to the parameter. The relay device may forward a signal between a first wireless device and a second wireless device based on the configuring.
