Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beamforming network structures are complex and inefficient, particularly at high frequencies, requiring long times for beamforming communication and lacking precise beam angle control, making them unsuitable for high-speed data transmission protocols like 60 GHz near field communication.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical beamforming network structure is used to control output beam direction, then beam direction control is achieved, but the structure becomes complicated and difficult to realize at high frequency
Solution Approach 1:
The patent divides the beamforming network into multiple independent sub-networks, each handling a specific beam direction. This segmentation allows each sub-network to be simpler in structure while collectively achieving comprehensive beam direction control, resolving the contradiction between operational capability and structural complexity
Solution Approach 2:
The patent transitions from controlling beam direction through complex phase shifting in a single network to using spatial arrangement and signal combination across multiple sub-networks. This dimensional change in the control approach simplifies individual network structures while maintaining overall beam direction control capability
2Reliability
If a typical beamforming network is used for beamforming communication, then communication is established, but a comparatively long time is required
Solution Approach 1:
The patent pre-establishes multiple sub-networks configured for different beam directions before communication begins. When communication is needed, the system can immediately activate the appropriate pre-configured sub-network without performing complex real-time beamforming calculations, thus reducing beamforming time while maintaining communication reliability
Solution Approach 2:
The patent enables dynamic selection and switching between multiple pre-configured sub-networks based on communication requirements. This dynamic approach allows the system to quickly adapt to different beamforming scenarios without the time penalty of reconfiguring a single complex network in real-time
3Reliability
If a typical beamforming network is used, then beamforming communication is possible, but precise beam angle control cannot be achieved
Solution Approach 1:
The patent divides the overall beamforming task into multiple sub-networks, each optimized for specific beam angles. This segmentation allows each sub-network to achieve precise angle control within its designated range, and the collection of all sub-networks provides comprehensive precise control across the full angular range, resolving the contradiction between communication capability and angle control precision

AI summary
A control system connected to a plurality of array antenna performs beamforming. The control system comprises a beam radiation controller for requesting a predetermined first antenna group to radiate beams and requesting a second antenna group including the first antenna group to radiate beams to an optimized sector, a beam receiver for receiving response beams from the first antenna group and the second antenna group, and a sector selector for setting up an optimized sector based on the received beams for the first antenna group, and transmitting information on the optimized sector to the beam radiation controller in order to control the second antenna group to radiate beams to the optimized sector.
