Stand-Alone IIoT Sidelink Profiles for Base-Station-Free Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication technologies, particularly in industrial Internet of Things (IIoT) deployments, lack flexibility and are not well-suited for environments out of base station coverage, such as shielded production plants, where different clusters of sensor/actuator devices have varying quality of service requirements and may relocate.
Innovation Solution
A stand-alone sidelink system is implemented, where user equipment (UEs) are preconfigured with multiple profiles and a controller UE broadcasts system information to enable flexible sidelink communications, allowing UEs to operate independently of a serving base station, with a coordinator UE managing different clusters and providing radio resource configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sidelink communication is implemented in shielded environments without base station coverage, then independence from base station is improved, but system configuration flexibility deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple profiles in UEs before deployment. These profiles contain various sidelink communication parameters that can be selected based on different operational scenarios. When a UE enters a shielded environment, it can autonomously select an appropriate pre-configured profile without requiring base station intervention, thus maintaining independence while preserving configuration flexibility.
Solution Approach 2:
The patent implements dynamics through the coordinator UE that dynamically selects and indicates specific profiles to be used in different clusters. The coordinator UE can adaptively choose from multiple pre-configured profiles based on current environmental conditions and quality of service requirements, allowing the system to remain flexible and adaptable rather than static.
2Adaptability or versatility
If multiple preconfigured profiles are implemented for different clusters, then quality of service adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the system into clusters, each with specific quality of service requirements. Instead of requiring every UE to handle all possible configuration scenarios, the coordinator UE segments the decision-making process by selecting appropriate profiles for each cluster. This reduces the effective complexity individual UEs must manage while maintaining overall system adaptability.
Solution Approach 2:
The coordinator UE acts as an intermediary that manages the complexity of multiple profiles. Rather than requiring each UE to independently manage and select from numerous profiles, the coordinator UE receives indications of quality of service requirements and selects appropriate profiles, then indicates them to UEs in the cluster. This intermediary role simplifies the profile management burden on individual devices.
3Adaptability or versatility
If stand-alone sidelink is implemented for IIoT, then deployment flexibility in shielded environments is improved, but resource allocation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple radio resource profiles containing various resource allocation parameters before deployment. These profiles include settings for different resource pools, modulation schemes, and other radio resources. When deployed in shielded environments, UEs can autonomously select appropriate pre-configured resource profiles without base station assistance, achieving deployment flexibility while avoiding real-time resource allocation complexity.

AI summary
Wireless communications systems and methods related to stand-alone sidelink communication are provided. A first user equipment (UE) transmits a sidelink system information signal including an indication of a first preconfigured profile of a plurality of preconfigured profiles. The first UE communicates, with a second UE, a first sidelink transmission based at least in part on the first preconfigured profile.
