Solution Overview
Problem
The increasing demand for faster and more efficient wireless communication systems faces challenges in managing beam resources effectively, leading to resource shortages and high energy consumption, particularly in next-generation mobile communication systems.
Innovation Solution
A method and apparatus for transmitting and receiving channel state information (CSI) that includes configuring and managing beam resources by turning on/off specific reference signal resources based on to-be-turned-on and/or to-be-turned-off indications, optimizing beam usage and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam resources are continuously maintained to ensure reliable wireless communication, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic beam management by transitioning from continuous beam maintenance to periodic beam reporting and updating. The network device configures periodic CSI reporting, where the terminal device reports channel state information at predetermined intervals rather than continuously, allowing beams to be maintained only when necessary while reducing energy consumption during stable communication conditions.
Solution Approach 2:
The patent introduces dynamic beam adjustment mechanisms where the terminal device determines whether to report CSI based on changing channel conditions. The system dynamically switches between continuous and periodic reporting modes, and adjusts beam parameters based on measured channel quality, ensuring reliable communication only when channel conditions warrant it rather than maintaining fixed continuous beams.
2Adaptability or versatility
If multiple reference signal resources are continuously monitored to optimize beam selection, then beam optimization is improved, but processing complexity increases
Solution Approach 1:
The patent implements partial monitoring by having the terminal device evaluate multiple reference signal resources but report CSI only when specific conditions are met. The device performs partial measurements on configured reference signals and selectively reports based on whether channel changes exceed thresholds, reducing processing complexity while maintaining beam optimization capabilities when needed.
Solution Approach 2:
The network device pre-configures multiple reference signal resources and reporting conditions before terminal operation. The terminal device prepares measurement configurations and evaluation criteria in advance, so when channel conditions change, the device can quickly determine whether reporting is needed without real-time complex decision-making, reducing instantaneous processing complexity.
