Bidirectional Data Transmitter Packet Segmentation for Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with many participants, channels with low data throughput and large range suffer from interference, leading to collisions and data losses due to inefficient channel utilization.
Innovation Solution
A data transmitter divides a data packet into multiple shorter transmission packets, channel-codes them to require only a portion for decoding, and monitors the frequency channel to avoid sending packets during interference, allowing for improved channel occupancy and reliability by omitting or delaying transmissions as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data packets are transmitted continuously in bidirectional networks, then channel throughput is improved, but data losses due to interference and collisions increase
Solution Approach 1:
The patent divides data packets into multiple sub-packets and transmits them at different time slots. This segmentation allows the system to monitor interference between sub-packets and selectively retransmit only those affected by collisions, thereby maintaining high channel throughput while improving data transmission reliability through targeted error correction.
2Productivity
If transmission time slots are shortened to increase channel utilization, then productivity is improved, but the buffer time needed to prevent packet overlap is reduced, worsening reliability
Solution Approach 1:
The patent implements periodic monitoring of sub-packet transmissions and uses systematic retransmission protocols. By periodically checking for collisions and retransmitting affected sub-packets in organized cycles, the system can use shorter time slots to increase channel utilization while maintaining reliability through structured error handling and buffer management.
3Reliability
If buffer time between time slots is increased to prevent packet overlap, then reliability is improved, but channel occupancy is reduced, worsening productivity
Solution Approach 1:
The patent applies partial buffering by monitoring specific sub-packets for collisions and applying buffer protection only where needed. Instead of uniformly increasing buffer time across all transmissions, the system selectively buffers only the sub-packets that show signs of interference, thereby maintaining high channel occupancy while ensuring reliability through targeted protection.
4Reliability
If all sub-packets are transmitted to ensure complete data delivery, then reliability is improved, but the complexity of managing retransmissions and channel monitoring increases
Solution Approach 1:
The patent implements feedback mechanisms where the receiving station monitors incoming sub-packets for collisions and sends retransmission requests only for affected packets. This feedback-driven approach ensures complete data delivery by selectively retransmitting only the necessary sub-packets, thereby maintaining high reliability while reducing the complexity of managing full retransmission protocols.

AI summary
Exemplary embodiments create a data transmitter. The data transmitter comprises a device for generating transmission data packets, configured to split a first data packet intended for a first data receiver into several transmission data packets, each of which is shorter than the first data packet. Furthermore, the data transmitter comprises a device for sending data packets, configured to transmit the transmission data packets intended for the first data receiver over a communication channel at a time interval.The device for sending data packets can be configured to: - send at least one further data packet to the first data receiver or a second data receiver at the time interval between the multiple data packets intended for the first data receiver; or - not send, only partially send, or send later a data packet pending transmission from among the multiple data packets if another data packet is pending transmission at the time the first data packet is sent; or - not send, only partially send, or send later a data packet pending transmission from among the multiple data packets depending on external conditions; or - not send, only partially send, or send later a data packet pending transmission from among the multiple data packets via the communication channel if a disturbance or transmission from another data sender is detected at the time the data packet is sent.
