UE Context Scenario Signaling for Adaptive Wireless Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently and accurately identify context scenarios for user equipment (UE) based on sensor data, leading to suboptimal resource utilization, power consumption, and increased signaling overhead.
Innovation Solution
User equipment (UE) uses sensor fusion and machine learning techniques to identify context scenarios, which are then indicated to a base station (BS) for optimized configuration, reducing manual user actions and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the network is upgraded to support higher data rates and lower latency, then network performance is improved, but device complexity and cost increase
Solution Approach 1:
The network configuration is segmented into multiple scenarios (e.g., enhanced mobile broadband, ultra-reliable low-latency communication, massive machine type communication) with specific parameter sets for each. This allows the network to optimize for different service requirements without requiring a complete system redesign, thereby improving data rates for specific scenarios while managing overall device complexity through modular configuration.
Solution Approach 2:
The patent implements dynamic configuration where network parameters are adjusted based on real-time scenario requirements. The network can dynamically switch between different configuration sets depending on the active service scenario, enabling high data rates when needed while maintaining lower complexity during normal operation. This dynamic adaptation resolves the contradiction by making complexity conditional rather than constant.
2Adaptability or versatility
If new radio access technology is deployed to support diverse services, then service diversity is improved, but compatibility with existing devices deteriorates
Solution Approach 1:
The patent creates a universal configuration framework that can accommodate multiple service scenarios through a common parameter structure. The same basic configuration mechanism serves both legacy services and new services (e.g., VR, autonomous driving), ensuring that existing devices can operate with new network deployments. The multi-functional configuration system maintains compatibility while enabling service diversity through scenario-specific parameter adjustments rather than fundamental architectural changes.
3Adaptability or versatility
If frequent configuration updates are provided to adapt to changing scenarios, then adaptability is improved, but signaling overhead and network resource consumption increase
Solution Approach 1:
The patent implements periodic configuration updates triggered by scenario changes rather than continuous updates. The network monitors for scenario transitions and provides configuration updates only when necessary (e.g., when a device transitions from idle to active service, or when service requirements change). This periodic action pattern maintains configuration adaptability while significantly reducing signaling overhead compared to continuous update mechanisms.
Solution Approach 2:
The patent pre-configures multiple scenario-specific parameter sets in advance. When a scenario change is detected, the network can immediately activate the pre-prepared configuration rather than calculating and transmitting new parameters in real-time. This preliminary preparation reduces the signaling overhead and processing resources needed during actual scenario transitions, as the adaptive configuration is already computed and stored.

AI summary
Wireless communication systems and methods related to user equipment (UE) context scenario indication-based configurations in a wireless communication network are provided. A UE obtains, from one or more sensors, sensor data. The UE identifies, based on the sensor data, a first context scenario associated with a surrounding environment of the UE or a user status. The UE transmits, to a base station (BS), an indication of the first context scenario. The UE receives, from the BS in response to the indication, a first configuration for the first context scenario.
