Multi-Band Wireless Transmission With Unified Sequence Number Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems using multiple frequency bands, the sequence numbers of data are managed independently for each band, leading to disrupted transmission timing and potential loss of data due to misordering during retransmission.
Innovation Solution
A wireless communication device that collectively manages sequence numbers across multiple bands and controls transmission and reception of data using a unified notification method to ensure synchronized data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sequence numbers are managed independently for each band to enable parallel transmission, then transmission speed is improved, but data ordering is disrupted and reliability deteriorates
Solution Approach 1:
The patent merges the sequence number management across multiple bands into a unified system. A single counter generates sequence numbers that are assigned to data packets regardless of which band they are transmitted on, ensuring global ordering while allowing parallel transmission across multiple bands simultaneously.
Solution Approach 2:
The sequence number management system is designed to be universal across all bands. The same sequence number counter and management logic serves all frequency bands, providing a unified ordering mechanism that works consistently whether data is transmitted on one band or multiple bands simultaneously.
2Productivity
If transmission rights are acquired in multiple bands simultaneously to increase throughput, then productivity is improved, but transmission timing becomes unsynchronized and data loss risk increases
Solution Approach 1:
The patent implements feedback mechanisms where the transmitting device monitors transmission status across all bands and uses acknowledgment packets to confirm successful reception. The receiving device sends ACK packets that provide feedback about which sequence numbers were successfully received, allowing the transmitter to retransmit only the missing packets regardless of which band they were originally sent on.
Solution Approach 2:
The patent establishes preliminary ordering of data packets using sequence numbers before transmission begins. This preliminary organization ensures that even if packets are transmitted out of order across different bands, the receiving device can reorder them correctly using the sequence number information that was assigned in advance.
