Inverse Data Sequence Transmission for Mobile Base Station Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems require significant control and coordination between base stations and often result in redundant transmissions to user terminals, especially in dynamic cell selection scenarios, which can be inefficient.
Innovation Solution
Configuring base stations to transmit data segments in inverse sequences, allowing user terminals to switch between base stations with reduced coordination and redundant transmissions, with synchronization only needed after all data segments are received, thereby minimizing control and redundant transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations transmit data segments in the same sequence, then coordination between base stations is required every time the user terminal switches base stations, but this increases control overhead and coordination complexity
Solution Approach 1:
The patent applies inversion by transmitting data segments in opposite sequences from different base stations. When a user terminal switches from one base station to another, the inverse sequence ensures that the terminal receives data segments in the correct chronological order without requiring complex coordination between base stations. This resolves the contradiction by eliminating coordination overhead while maintaining data delivery reliability.
2Reliability
If base stations coordinate frequently to maintain synchronization, then data delivery reliability is improved, but control overhead and transmission efficiency deteriorate
Solution Approach 1:
By using inverse sequences for data segment transmission from different base stations, the patent eliminates the need for frequent coordination and synchronization between base stations. The terminal can seamlessly switch between base stations while maintaining correct data ordering, thus improving transmission efficiency without sacrificing data delivery reliability.
Solution Approach 2:
The system enables self-service by allowing the user terminal to automatically handle data segment reordering and base station switching without requiring external coordination signals. The terminal receives data segments from multiple base stations and reconstructs the correct sequence locally, eliminating the need for base station coordination overhead.
3Adaptability or versatility
If the system allows dynamic base station switching, then adaptability to changing reception conditions is improved, but the amount of redundant transmissions increases
Solution Approach 1:
The inverse sequence transmission method allows the system to support dynamic base station switching while minimizing redundant transmissions. When the terminal switches base stations, the opposite sequencing ensures that data segments are received in the correct order without requiring retransmission, thus maintaining adaptability while reducing waste.
Solution Approach 2:
The system performs preliminary action by pre-configuring inverse sequences for data segment transmission from different base stations. This preparation in advance allows the terminal to switch between base stations without causing redundant transmissions, as the correct sequence is already established in the transmission plan.
