UE Beam Management via Channel Condition Value Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effective beam management, particularly in inter-RAT scenarios, where wide beams may not provide sufficient beamforming gain, leading to poor channel condition value measurements and suboptimal network performance due to frequent SSB switches and increased signaling overhead.
Innovation Solution
A method where user equipment (UE) measures beams using a wide beam to determine channel condition values and modifies these values based on beamforming gain, allowing for improved reporting to the base station, which enables more accurate beam management and reduces signaling overhead by refining beam measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wide beams are used for beam management in inter-RAT scenarios, then beam coverage is improved, but beamforming gain is insufficient leading to poor channel condition measurements
Solution Approach 1:
The patent dynamically adjusts beam management parameters based on beam type identification. The system determines whether a beam is wide or narrow and applies different measurement and reporting strategies accordingly, making the beam management process adaptive rather than static
Solution Approach 2:
The patent modifies measurement parameters based on beam characteristics. Specifically, it adjusts channel condition value measurements and reporting behavior according to whether the beam is wide or narrow, changing the measurement parameters to match the beam type for optimal performance
2Measurement precision
If frequent beam measurements are performed, then beam management accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and processes only the essential beam type information from measurements. By identifying whether beams are wide or narrow and reporting only this critical classification along with modified channel condition values, it reduces the amount of signaling data while maintaining management accuracy
Solution Approach 2:
The patent performs partial measurement actions by focusing on key beam characteristics rather than exhaustive measurements. It modifies channel condition values based on beam type and reports only the necessary information, avoiding excessive signaling while achieving sufficient beam management accuracy
3Measurement precision
If narrow beams are used for measurement, then beamforming gain is improved, but measurement complexity increases
Solution Approach 1:
The patent segments the beam management process into distinct phases: wide beam initial measurement for coverage, followed by narrow beam refinement for precision. This segmentation allows the system to benefit from narrow beamforming gain only when necessary, reducing overall measurement complexity while maintaining accuracy where needed
