Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in dynamically adjusting beam information, such as beam shape and neighboring information, to effectively adapt to changing channel conditions and interference, leading to potential beam or radio link failures.
Innovation Solution
The system employs dynamic alteration of beam information using MAC-CE and DCI transmissions, allowing for quick switching between different beam configurations based on indications received from the network, thereby reducing latency and overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beam information is dynamically adjusted to adapt to changing channel conditions, then beam flexibility and adaptability are improved, but system complexity and overhead increase
Solution Approach 1:
The patent implements dynamic beam information alteration by enabling the base station to transmit updated beam shape and inter-beam pointing direction information through MAC-CE and DCI signaling. This allows the UE to switch between different beam configurations in real-time based on changing channel conditions, achieving adaptability without requiring complete system redesign.
Solution Approach 2:
The patent changes key beam parameters including beam shape (e.g., beam width, beam direction) and inter-beam pointing direction information dynamically. By modifying these parameters through controlled signaling mechanisms, the system adapts to channel variations while managing complexity through parameter-specific optimization rather than complete reconfiguration.
2Speed
If beam information switching is accelerated to reduce latency, then communication speed is improved, but error rates and interference increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple beam information sets at the base station before actual switching is needed. The UE receives and stores multiple beam configurations in advance, allowing rapid switching when channel conditions change without requiring real-time computation or configuration, thus reducing latency while maintaining reliability.
Solution Approach 2:
The patent implements feedback mechanisms where the UE reports beam measurement information and channel conditions back to the base station. This feedback loop enables the base station to select optimal beam configurations in advance and transmit appropriate switching indications, ensuring fast and accurate beam switching with reduced errors.
3Adaptability or versatility
If more beam configurations are available to improve adaptability, then beam flexibility increases, but information overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the essential beam information parameters (beam shape and inter-beam pointing direction) from the complete beam configuration data. By focusing signaling on these critical parameters rather than transmitting all possible configuration details, the system achieves high adaptability while minimizing information overhead and processing requirements.
Solution Approach 2:
The patent segments beam information into distinct components: beam shape information and inter-beam pointing direction information. This segmentation allows selective transmission and processing of only the necessary components for each beam configuration, reducing overall information overhead while maintaining the flexibility to support multiple configurations.
