Persistent Beamforming Profiles for Fixed Wireless Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overhead associated with beamforming processes in wireless communications, particularly in the 60 GHz frequency band, reduces the available time for data communication within beacon intervals.
Innovation Solution
Implementing persistent-profile based beamforming, where a beamforming profile created in one beacon interval is reused in subsequent intervals, reducing the need for repeated beamforming processes and optimizing antenna configurations based on fixed spatial relationships between wireless stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming process is performed in every beacon interval, then directional communication quality is maintained, but overhead time increases and data communication bandwidth decreases
Solution Approach 1:
The system performs beamforming profile creation in advance during the first beacon interval and stores it in memory. This preliminary action allows subsequent beacon intervals to reuse the stored profile without repeating the full beamforming process, thereby reducing overhead time while maintaining communication quality for fixed-location stations.
Solution Approach 2:
The patent creates a beamforming profile copy that is stored in memory and reused across multiple beacon intervals. Instead of regenerating the beamforming parameters each interval, the system copies and reuses the established profile, significantly reducing the time required for beamforming operations in subsequent intervals.
2Adaptability or versatility
If beamforming profile is created in each beacon interval, then adaptability to location changes is achieved, but processing time and overhead increase
Solution Approach 1:
The system dynamically adapts its beamforming approach based on station mobility characteristics. For fixed-location stations, it uses persistent reused profiles to maximize productivity. For mobile stations, it periodically updates profiles to maintain adaptability. This dynamic adjustment allows the system to optimize for either adaptability or productivity depending on the operational context.
Solution Approach 2:
The patent applies different beamforming strategies to different types of wireless stations based on their mobility characteristics. Fixed-location stations receive persistent profile treatment with minimal overhead, while mobile stations receive periodic profile updates. This localized quality approach ensures each station type receives the appropriate level of adaptability without unnecessarily impacting overall system productivity.
3Loss of time
If persistent beamforming profile is reused, then overhead is reduced and bandwidth increases, but ability to track moving stations deteriorates
Solution Approach 1:
The system segments its beamforming approach by creating separate handling paths for fixed-location and mobile stations. Fixed stations use persistent profile reuse with minimal overhead, while mobile stations receive periodic tracking updates. This segmentation allows the system to reduce overall overhead while maintaining tracking capability for mobile stations through targeted periodic updates.
