Coordinator Base Station for Link-Level Acknowledgment Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication systems face challenges in efficiently coordinating link-level communications between user equipment and multiple base stations, particularly in handling acknowledgments and data routing, which affects data transmission quality and bandwidth utilization.
Innovation Solution
The system includes user equipment and base stations with processors that broadcast data messages, receive acknowledgments, and send indicators to manage data routing effectively, using acknowledgments to determine successful data transmission and adjust communication parameters, such as grant information and error correction, to optimize link-level communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base stations are used for link level communication, then reliability is improved through diversity, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent introduces a coordinator base station that acts as an intermediary to manage acknowledgments and coordinate retransmissions among multiple base stations. The coordinator receives feedback from all base stations, determines which base station should perform retransmission, and sends control messages to coordinate the process, thereby reducing complexity while maintaining reliability benefits
Solution Approach 2:
The patent combines the functions of multiple base stations into a unified coordination mechanism where one base station (the coordinator) consolidates acknowledgment reception and retransmission decision-making. This merging approach allows multiple base stations to provide diversity gain while centralizing control logic to reduce overall system complexity
2Reliability
If acknowledgments are sent from all base stations, then reliability is improved through feedback, but loss of information increases due to duplicate acknowledgments
Solution Approach 1:
The patent extracts the acknowledgment coordination function from individual base stations and concentrates it in a coordinator base station. The coordinator collects acknowledgments from all base stations, removes duplicates, and generates a single consolidated acknowledgment message, thereby preventing information loss while maintaining the reliability benefits of multi-base station feedback
Solution Approach 2:
The patent uses copying mechanisms where the coordinator base station receives copies of acknowledgments from multiple base stations, processes them to identify unique information, and generates a single authoritative acknowledgment. This copying approach allows comprehensive feedback collection while eliminating redundant information transmission
3Reliability
If data is broadcast to multiple base stations, then reliability is improved through multiple reception paths, but productivity decreases due to processing overhead
Solution Approach 1:
The patent segments the data processing function by dividing responsibilities between the transmitting device and multiple base stations. The transmitting device sends data to multiple base stations, but only the coordinator base station performs full processing and acknowledgment generation. Other base stations perform lighter processing (reception and acknowledgment generation), which reduces overall processing overhead while maintaining reliability through multiple reception paths

AI summary
Systems, devices and methods for link level communication between a user equipment and plurality of network devices are described. A user equipment can include at least one processor configured to: after broadcasting a first data message to the plurality of base stations, receive one or more acknowledgements, corresponding to the first data message, from at least one of the plurality of base stations; and upon receipt of at least one acknowledgement, broadcast an indicator to the plurality of base stations, the indicator providing an indication of at least one of the at least one received acknowledgement.
