Base Station Spatial Information Beam Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems face challenges in maintaining communication quality between terminals and base stations due to spatial conditions that affect radio wave propagation, leading to interference and deteriorated communication quality, especially when relying solely on communication quality measurement reports.
Innovation Solution
Incorporating a controller and communicator in base stations that utilize spatial information, such as location, obstacle data, and weather conditions, to adjust beam formation and coordination between base stations, thereby improving communication quality by dynamically managing arbitration areas and beam selection.

Engineering Contradiction Analysis
1Object-generated harmful factors
If coordinated control is performed based solely on quality measurement results, then interference between cells is suppressed, but communication quality between terminal and base station may deteriorate due to unreflected spatial conditions
Solution Approach 1:
The patent introduces spatial condition information as an intermediary factor that mediates between the quality measurement result and the coordinated control decision. The controller integrates both quality measurement results and spatial condition information to make comprehensive coordination decisions, preventing the deterioration of communication quality while maintaining interference suppression.
Solution Approach 2:
The patent changes the parameter basis for coordinated control from solely quality measurement results to a combination of quality measurement results and spatial condition information. This parameter expansion allows the system to account for spatial factors such as terminal-base station geometry that affect communication quality but were not captured by quality measurements alone.
2Reliability
If spatial condition information is integrated into coordinated control, then communication quality between terminal and base station is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by having the terminal report spatial condition information in advance, before the coordinated control decision is made. The controller receives and stores this spatial information, then uses it during the coordination process. This pre-collection approach simplifies the real-time processing burden on the controller.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal provides feedback on both quality measurement results and spatial condition information to the controller. This feedback loop enables the controller to make informed coordinated control decisions that consider both communication quality and spatial factors, while the feedback structure itself organizes the complexity into manageable information flows.
