Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR and future 6G communication systems, managing beam switching between different antenna configurations in mmWave and terahertz frequency bands is challenging due to the need for efficient energy use and mobility performance, especially when channel conditions and data transmission requirements vary.
Innovation Solution
A method and apparatus for beam switching in communication nodes, where a first communication node sends a switching request to a second node to switch from a first beam to a second beam, allowing for flexible beam selection based on current communication scenarios, with the second node determining resource configuration and beam management to ensure consistent beam pointing and optimal signal transmission.

Engineering Contradiction Analysis
1Productivity
If beam switching is implemented to improve mobility performance, then communication efficiency is improved, but device complexity increases due to multiple antenna configurations
Solution Approach 1:
The patent implements dynamic beam switching between different beam configurations (first beam and second beam) based on communication scenarios. The communication node can switch between a first beam configuration optimized for certain conditions and a second beam configuration optimized for other conditions, enabling adaptive response to changing channel states and mobility requirements without permanently increasing hardware complexity
Solution Approach 2:
The patent changes beam parameters (beam width, direction, configuration) dynamically based on communication scenarios. By adjusting beam parameters rather than hardware architecture, the system achieves improved mobility performance and communication efficiency while avoiding permanent increases in device complexity
2Measurement precision
If narrower beams are used to improve signal quality, then transmission precision is improved, but power consumption increases due to more antenna units
Solution Approach 1:
The patent dynamically switches between a first beam configuration (potentially narrower for high signal quality) and a second beam configuration (potentially wider for lower power consumption) based on communication scenarios. This dynamic adaptation allows the system to use high-precision narrow beams only when necessary, reducing overall power consumption while maintaining signal quality requirements
Solution Approach 2:
The patent changes beam parameters (width, direction, configuration) based on communication needs. By adjusting beam width and other parameters dynamically, the system achieves optimal signal quality only when required, rather than continuously using high-precision narrow beams that consume more power
3Use of energy by moving object
If wider beams are used to reduce power consumption, then energy efficiency is improved, but signal quality deteriorates
Solution Approach 1:
The patent implements dynamic switching between beam configurations, using wider beams for power efficiency when channel conditions permit and narrower beams for signal quality when needed. This dynamic approach allows the system to achieve good energy efficiency on average while maintaining signal quality requirements through selective use of narrower beams in appropriate scenarios
