Dynamic Signal Quality Feedback Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face limitations in efficiently allocating signal quality feedback bandwidth, particularly when managing multiple wireless devices with varying channel conditions, leading to bottlenecks in supporting active devices and optimizing data exchange.
Innovation Solution
The method involves grouping wireless devices based on their signal quality feedback bandwidth indicators and dynamically reallocating bandwidth by moving devices between groups based on channel stability, allowing devices with better conditions to reduce feedback frequency and freeing up bandwidth for new devices, thus optimizing the allocation of signal quality feedback slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth is allocated to all wireless devices for signal quality feedback, then all devices can maintain communication quality, but the system reaches capacity limits and cannot support additional active devices
Solution Approach 1:
The patent dynamically changes the feedback frequency parameter for different devices based on their channel conditions. Devices with stable channels reduce their feedback frequency, freeing up bandwidth resources that can then be allocated to support more active devices in the system.
Solution Approach 2:
The patent applies different feedback frequencies to different devices based on their individual channel conditions. Instead of uniform feedback allocation, each device receives customized feedback requirements - devices with poor channel conditions maintain higher feedback frequency while devices with stable channels reduce feedback frequency.
2Reliability
If all wireless devices send signal quality feedback at high frequency, then communication reliability is maintained, but bandwidth resources are exhausted and data exchange efficiency decreases
Solution Approach 1:
The patent dynamically adjusts the feedback frequency parameter based on channel stability measurements. When channels are stable, the feedback frequency parameter is reduced, freeing bandwidth for data transmission and improving overall data exchange rates while maintaining adequate communication quality monitoring.
3Ease of operation
If uniform signal quality feedback bandwidth is allocated to all devices, then allocation simplicity is maintained, but devices with better channel conditions waste bandwidth resources
Solution Approach 1:
The patent implements differentiated feedback frequency allocation based on individual device channel conditions. Devices experiencing stable channels are assigned lower feedback frequencies, while devices with poor channel conditions receive higher feedback frequencies, optimizing bandwidth utilization across the system.
Solution Approach 2:
The patent makes the feedback frequency allocation dynamic rather than static. The system continuously monitors channel conditions and adjusts feedback frequencies in real-time, allowing devices to transition between different feedback rates as channel conditions change, thereby optimizing bandwidth efficiency.

AI summary
A first amount of bandwidth is allocated to a first wireless device to send signal quality information to a base station. Based on a first indicator of wireless link conditions associated with the first wireless device, and a second indicator of wireless link conditions associated with a second wireless device, a second amount of bandwidth is allocated to the first wireless device to send signal quality information to the base station.
