Device-Initiated Beam and CSI Reporting for Adaptive Wireless Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for wireless devices to initiate reporting of channel state information and beam reports, limiting the flexibility and adaptability of communication protocols.
Innovation Solution
Wireless devices are enabled to transmit reports such as beam reports and channel state information (CSI) based on channel quality measurements, with the capability to use uplink resources configured by the base station or determined through downlink control information, and triggers for aperiodic reporting are provided to facilitate device-initiated reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless devices use only base station-initiated reporting mechanisms, then network control is maintained, but reporting flexibility and adaptability are limited
Solution Approach 1:
The patent implements dynamic reporting initiation capability where wireless devices can autonomously decide when to transmit reports based on real-time channel quality measurements. The device transitions from passive reporting (network-initiated) to active reporting (device-initiated) based on measured conditions, making the reporting mechanism flexible and adaptive to changing channel conditions without requiring complex reconfiguration
Solution Approach 2:
The wireless device performs self-assessment of channel quality through measurements and autonomously determines when reporting is necessary. The device uses its own measurements to trigger reports, eliminating the need for continuous network scheduling decisions and reducing signaling overhead while improving reporting relevance
2Productivity
If wireless devices initiate reports autonomously, then reporting efficiency improves, but resource management complexity increases
Solution Approach 1:
The base station pre-configures the wireless device with reporting parameters, measurement configurations, and resource allocations before autonomous reporting begins. This preliminary setup includes threshold values and resource indications that guide the device's autonomous decisions, reducing the complexity of real-time resource management while maintaining reporting efficiency
Solution Approach 2:
The patent employs parameter-based control where the device compares measured channel quality against pre-configured thresholds and parameters. By changing reporting behavior based on parameter comparisons rather than complex algorithms, the device achieves efficient autonomous reporting with manageable complexity
3Adaptability or versatility
If multiple reporting modes are supported, then system adaptability increases, but configuration complexity increases
Solution Approach 1:
The patent creates a universal reporting framework where a single configuration mechanism supports multiple reporting modes (aperiodic, periodic, and event-triggered). The base station configures resource pools that can be dynamically allocated to different reporting types, allowing the system to support versatile reporting behaviors without requiring separate configuration procedures for each mode
Solution Approach 2:
The patent introduces an intermediary configuration layer where the base station provides high-level reporting configurations and resource indications, which then translate into specific reporting behaviors. This intermediary layer simplifies device configuration by abstracting away the complexity of managing multiple reporting modes, as the device follows straightforward rules based on received configurations rather than managing complex mode-specific parameters
Data Source
AI summary
A wireless device may communicate with a base station. At least some reporting by the wireless device may be initiated by a wireless device. The wireless device may indicate a capability for wireless device-initiated reporting, for example, to inform a base station of the wireless device's capability to initiate beam reporting.
