Terminal Beam and CSI Reporting Control for Lower Network Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems waste resources due to terminals reporting beam and CSI reports when their state does not change or changes minimally, leading to unnecessary communication and power consumption.
Innovation Solution
Implementing methods for terminals to report beam and CSI reports using different time domain behaviors, such as event-based reporting, periodic/semi-persistent reporting conditions, and aperiodic reporting, to reduce overhead and conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals periodically report beam and CSI reports regardless of state changes, then the network can maintain real-time channel awareness, but communication resources are wasted when terminal state does not change
Solution Approach 1:
The patent applies dynamic reporting by allowing terminals to adjust reporting behavior based on their movement state. When terminals are stationary or moving slowly, reporting is reduced or suspended. When terminals move quickly, reporting frequency increases. This dynamic adaptation resolves the contradiction between maintaining accurate channel awareness and reducing communication resource waste.
Solution Approach 2:
The patent changes the reporting parameter (reporting frequency) based on terminal movement state. The network configures different reporting periods or triggers reporting only when state changes exceed thresholds. This parameter adjustment allows the system to maintain reliability when needed while reducing resource consumption when unnecessary.
2Loss of information
If terminals report beam and CSI reports frequently, then the network can track terminal state changes accurately, but power consumption increases
Solution Approach 1:
The patent implements dynamic reporting where terminals adjust their reporting behavior based on detected state changes. Terminals monitor their own movement and only report when changes exceed configured thresholds. This dynamic approach ensures accurate tracking when terminals move while conserving power during stationary periods.
Solution Approach 2:
Terminals autonomously determine when reporting is necessary by monitoring their own state changes. The terminal compares current state with previous state and autonomously decides whether to trigger a report based on configured thresholds, reducing unnecessary power consumption while maintaining tracking accuracy.
3Device complexity
If analog beamforming uses time-division multiplexing for training signals, then device complexity is reduced, but training time increases
Solution Approach 1:
The patent segments the beam training process into multiple time slots, with each antenna panel or polarization direction transmitting training signals in turn through time-division multiplexing. This segmentation reduces the number of simultaneous AD/DA conversion devices needed while distributing the training time across multiple slots, thereby reducing device complexity at the cost of increased total training time.
