Engineering Contradiction Analysis
1Speed
If 5G systems use higher frequency bands to accomplish higher data rates, then data rate is improved, but signal attenuation increases and service availability deteriorates
Solution Approach 1:
The patent segments the service coverage area into multiple zones based on signal quality characteristics. By dividing the coverage area and applying different beamforming strategies to different segments, the system can maintain high data rates in favorable areas while ensuring basic service availability in areas with higher attenuation, thus resolving the contradiction between speed and reliability.
Solution Approach 2:
The patent dynamically changes transmission parameters including frequency selection, beamforming weights, and power allocation based on channel conditions. By adapting these parameters in real-time, the system optimizes the balance between achieving high data rates and maintaining service availability across varying propagation conditions.
2Length of stationary object
If beamforming and massive MIMO techniques are used to decrease propagation loss and increase transmission distance, then transmission distance is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary channel estimation and beamforming optimization before actual data transmission. By pre-computing beamforming weights and selecting optimal beams based on channel state information, the system extends transmission distance while avoiding the need for complex real-time computations during data transmission, thus managing system complexity.
Solution Approach 2:
The patent uses channel state information from reference signals (pilot signals) to create a model or copy of the channel characteristics. This channel model is then used to determine optimal beamforming strategies without requiring the system to directly process complex real-time channel variations, simplifying the overall system complexity while achieving extended transmission distance.
3Area of stationary object
If small cells and ultra-dense networks are deployed to improve coverage, then service coverage is improved, but network complexity and deployment difficulty increase
Solution Approach 1:
The patent combines multiple small cell base stations into coordinated groups that work together as a unified network entity. By merging the functionality of multiple nodes through coordinated beamforming and joint transmission, the system achieves extended service coverage while managing network complexity through centralized coordination rather than independent operation of each node.
