Branch Selection Transmission via Transport Block Serial Numbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multicarrier modulation techniques, high peak-to-average power ratios (PAPRs) lead to signal distortion and burst errors, complicating the transmission of information indicating branch selection, which requires additional error correction and increased complexity.
Innovation Solution
An information transmission apparatus determines serial numbers for information transport blocks based on branch selection information, allowing for the transmission of branch selection data without an additional transmission path, using predefined values and processing techniques to ensure accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional transmission path is provided for branch selection information, then transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent combines branch selection information with information transport block serial numbers by using the serial number fields to carry both the original serial number identification and the branch selection indication. This merging eliminates the need for separate transmission paths while maintaining both functions.
Solution Approach 2:
The serial number fields in information transport blocks are designed to serve multiple purposes: identifying the serial number of the information transport block and simultaneously indicating the selected branch. This multi-functionality removes the need for dedicated branch selection transmission resources.
2Reliability
If error correction code is added for branch selection information, then reliability is improved, but overhead increases
Solution Approach 1:
The patent merges branch selection information into the existing serial number structure of information transport blocks. By embedding the branch indication within the serial number field itself, no additional overhead bits are required for error correction specifically for branch selection, as the serial number structure already provides the necessary redundancy and error detection capabilities.
3Ease of operation
If serial numbers are transmitted without processing, then transmission simplicity is maintained, but detection accuracy decreases
Solution Approach 1:
The patent applies preliminary processing to serial numbers by encoding branch selection information into the serial number structure before transmission. The transmitter pre-processes the serial number to include branch indication, and the receiver performs corresponding detection based on predefined rules, improving detection accuracy while maintaining transmission simplicity.

AI summary
An information transmission apparatus, an information detection apparatus and a transmitter is provided where serial numbers of information transport blocks are determined according to information indicating branch selection, so as to transmit information on the branch selection by using the serial numbers of information transport blocks. Hence, no additional transmission path needs to be provided, and the information on the branch selection may be simply and conveniently transmitted and a probability of wrongly determining the information indicating branch selection may be reduced, thereby efficiently improving performance of the system.
