Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the resources required for the wireless signal processing unit are doubled in base station apparatuses, leading to increased costs and longer switching times when changing wireless schemes.
Innovation Solution
A control apparatus determines the optimal combination of base station and wireless signal processing apparatuses to minimize overlap in communication paths, activating or deactivating wireless signal processing units based on processing load, and controls transmission timing to share resources efficiently, allowing for seamless switching between wireless schemes without increasing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless signal processing is performed in both base station apparatus and wireless signal processing apparatus, then communication flexibility is improved, but device complexity increases due to doubled resources in base station apparatus
Solution Approach 1:
The patent divides the wireless signal processing function into two separate entities: base station apparatus and wireless signal processing apparatus. This segmentation allows the base station to focus on control functions while the wireless signal processing apparatus handles signal processing, eliminating the need for doubled resources in the base station while maintaining communication flexibility through coordinated operation between the two entities.
2Adaptability or versatility
If software replacement is performed to change wireless schemes, then adaptability is improved, but loss of time increases due to non-wireless communication time
Solution Approach 1:
The patent implements a standby system with pre-loaded software for different wireless schemes. When a scheme change is required, the system switches to the pre-prepared standby configuration, eliminating the need for time-consuming software replacement during operation. This preliminary preparation of alternative configurations enables rapid scheme changes without communication interruption.
3Area of stationary object
If base station apparatus are geographically distributed, then coverage area is improved, but device complexity increases due to reduced aggregation
Solution Approach 1:
The patent introduces a universal wireless signal processing apparatus that can be deployed in various locations and work with multiple base station apparatus. This universal component provides aggregation benefits even in geographically distributed scenarios, as multiple base stations can share common signal processing resources, reducing overall system complexity while maintaining wide coverage through strategic positioning of these multi-functional units.
