Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power concentration techniques for wireless communication, such as pointforming, do not always achieve high communication performance when applied to radio access networks due to excessive freedom in selecting transmission devices, leading to inefficiencies in control and processing load.
Innovation Solution
A system for efficiently selecting transmission devices by grouping them into groups based on predetermined criteria, allowing terminal devices to identify and connect with optimal groups for communication via point cells, reducing processing requirements and enhancing communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power concentration technique (pointforming) is applied to radio access network, then spatial multiplex capability is improved, but control complexity and processing load increase excessively
Solution Approach 1:
The patent segments the radio access network into multiple transmission device groups, where each group is responsible for a specific point cell. This segmentation reduces the control complexity by dividing the overall system into manageable units, while still maintaining the spatial multiplex capability through coordinated operation of multiple groups.
Solution Approach 2:
The patent introduces a group dimension in addition to the traditional cell dimension. Instead of managing individual transmission devices or single cells, the system operates at the group level, adding a hierarchical dimension that simplifies control while enabling advanced spatial multiplexing through group coordination.
2Reliability
If transmission devices are selected freely for point cell formation, then communication performance is improved, but processing load and control overhead increase
Solution Approach 1:
The patent performs preliminary grouping of transmission devices into fixed groups before point cell formation. This preliminary action reduces the processing load during operation, as the system only needs to select among pre-defined groups rather than evaluating all possible device combinations in real-time.
Solution Approach 2:
The patent assigns specific transmission device groups to specific point cells, creating localized responsibilities. Each group is optimized for its designated point cell, which improves communication performance through specialized configuration while reducing overall processing load by limiting the search space for device selection.
3Productivity
If multiple transmission devices are coordinated for point cell formation, then frequency utilization efficiency is improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent merges multiple transmission devices into coordinated groups that operate together for point cell formation. This merging improves frequency utilization efficiency through coherent signal combination while managing coordination overhead by establishing fixed group structures with predefined relationships.
