Wireless Booster Directional Timing Offset Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network boosters using directional transmission and reception techniques face challenges in providing consistent coverage to their entire coverage area due to the need to continually modify their orientations, leading to intermittent communication with mobile devices located in different directions.
Innovation Solution
The implementation of a scheme that provides mobile devices with timing offset information to determine optimal times for sending messages, allowing them to synchronize with the booster's directional reception orientation, thereby ensuring successful communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If directional transmission and reception techniques are used to achieve greater reach, then communication distance is improved, but coverage availability deteriorates because only part of the coverage area is served at any given time
Solution Approach 1:
The patent implements periodic beam sweeping where the booster alternates between transmission orientations and reception orientations in a cyclic pattern. This periodic action ensures that all directions within the coverage area are served over time, resolving the contradiction by making coverage availability reliable through systematic temporal distribution rather than simultaneous coverage.
Solution Approach 2:
The patent makes the transmission and reception orientations dynamic by allowing them to change over time according to a configured pattern. The mobile device determines appropriate transmission times based on current or predicted booster orientations, enabling the system to adapt to different spatial-temporal conditions and maintain reliable communication across the entire coverage area.
2Area of stationary object
If the booster continually modifies its directional transmission and reception orientations to cover the entire coverage area, then coverage area utilization is improved, but communication reliability deteriorates because messages can only be sent at certain times
Solution Approach 1:
The patent applies preliminary action by having the mobile device determine the appropriate transmission time in advance, based on configured timing offset information and the current or predicted booster orientation. This allows the device to prepare and send messages at optimal times before the booster's reception orientation changes, ensuring reliable communication while maintaining full coverage area utilization.
Solution Approach 2:
The system uses feedback mechanisms where the mobile device receives timing offset information from the booster and uses this feedback to determine when to transmit messages. This closed-loop approach ensures that transmission timing is continuously adapted to the booster's changing orientations, maintaining both full coverage area utilization and message transmission reliability.
3Reliability
If timing offset information is provided to synchronize mobile devices with booster orientations, then message transmission reliability is improved, but system complexity increases due to the need for timing coordination
Solution Approach 1:
The patent changes the parameter of timing offset information from a complex dynamic value to a static configured parameter that is provided to the mobile device. This simplification allows the device to calculate transmission times locally without continuous complex coordination, improving message transmission reliability while reducing system coordination complexity through parameter transformation.
