Multi-Band Wireless Device Unified Reception Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication using multiple bands, the efficiency of notifying reception results is low, and there is a risk of incorrect notification due to poor propagation characteristics in certain bands.
Innovation Solution
A wireless communication device that transmits a Setup signal containing setting information for a notification method for reception results across multiple bands, and subsequently transmits Data signals using these bands, allowing for efficient and reliable notification of reception results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retransmission is performed in each band separately, then communication reliability is improved, but notification efficiency deteriorates and resource usage becomes suboptimal
Solution Approach 1:
The patent merges the notification of reception results across multiple bands into a single unified notification process. Instead of notifying reception results separately for each band, the system combines them into one notification that covers all bands, thereby improving efficiency while maintaining reliability through the multi-band transmission capability.
Solution Approach 2:
The patent implements a universal notification mechanism that can operate across multiple bands simultaneously. The notification system is designed to handle reception results from all bands through a single process, making the system more versatile and efficient rather than requiring separate specialized notification for each band.
2Loss of information
If reception result is notified in bands with poor propagation characteristics, then notification completeness is improved, but notification accuracy deteriorates due to potential transmission failures
Solution Approach 1:
The patent performs preliminary actions by transmitting the Setup signal before actual data communication to establish the notification method and settings in advance. This preliminary configuration ensures that both transmission and reception sides agree on the notification protocol before actual notification occurs, preventing errors due to poor propagation characteristics during the notification phase.
Solution Approach 2:
The patent implements a feedback mechanism where the reception side notifies the transmission side of the reception result, and the transmission side uses this feedback to determine retransmission needs. This feedback loop operates across multiple bands with coordinated control to ensure accurate and complete notification while adapting to propagation conditions.
