Preconfigured Antenna Beamforming for Wireless Link Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with multiple antennas for different wireless links face antenna coupling issues, leading to usability problems due to interference and desense, particularly when operating at high speeds.
Innovation Solution
Preconfigured antenna beamforming configurations are determined and stored to avoid 'blackout regions' where antenna coupling is high, allowing the beamforming antenna system to operate without directing beams through these regions, thus reducing interference and maintaining low latency and high data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna systems operate simultaneously for different wireless links, then communication versatility and data throughput are improved, but antenna coupling and interference occur causing desense and reliability degradation
Solution Approach 1:
The patent applies preliminary action by pre-configuring beamforming parameters and identifying blackout regions before simultaneous antenna operation. The system determines beamforming configurations that avoid directing beams through blackout regions where antenna coupling occurs, preventing interference issues before they arise during multi-antenna operation.
Solution Approach 2:
The patent applies local quality by creating spatially-specific beamforming configurations for different angular regions. Different beamforming parameters are applied to different spatial zones, with specific configurations designed to avoid blackout regions where antenna coupling problems occur, while allowing optimal performance in safe regions.
2Productivity
If beamforming is used to direct communication beams, then data throughput and signal strength are improved, but beams may inadvertently pass through blackout regions causing antenna coupling and desense
Solution Approach 1:
The patent converts the harmful effect of blackout regions into a beneficial constraint by using them to define exclusion zones in beamforming configurations. The identified blackout regions become part of the beamforming parameter set, guiding the system to actively avoid these regions and thereby preventing antenna coupling while maintaining high data throughput in safe angular regions.
Solution Approach 2:
The patent applies parameter changes by adjusting beamforming parameters (angular positions, beam widths, power levels) based on the identified blackout regions. The system dynamically selects beamforming configurations from a set of pre-determined parameters that avoid directing beams through blackout regions, thereby eliminating antenna coupling while maintaining optimal data throughput.
3Reliability
If real-time beamforming optimization is performed to avoid blackout regions, then antenna coupling is reduced, but computational complexity and processing time increase
Solution Approach 1:
The patent dramatically reduces computational complexity by performing all beamforming optimization calculations in advance. Blackout regions are identified and beamforming configurations are pre-determined before actual communication operation. During runtime, the system simply selects from pre-configured parameters based on current angular positions, avoiding the need for complex real-time optimization calculations.
Solution Approach 2:
The patent applies segmentation by dividing the spatial environment into discrete angular regions and pre-calculating beamforming parameters for each segment. This segmentation allows the system to handle complex beamforming decisions through simple lookup and selection of pre-computed parameters for each angular segment, rather than performing continuous real-time optimization.

AI summary
System and techniques are provided for preconfigured antenna beamforming. A device having a first antenna system for communicating over a first wireless link and a second antenna system for communicating over a second wireless link may be provided. For different transmit power levels of the first and/or second wireless links, an antenna coupling factor between the first antenna system and the second antenna system may be measured for different beamforming configurations of the first antenna system, a received signal strength indicator (RSSI) of the first and/or second wireless link may be measured for the different beamforming configurations of the first antenna system, and a beamforming configuration at each of the different transmit power levels with the measured antenna coupling factor and the measured RSSI may be stored in a memory as a predefined beamforming configuration.
