Adaptive Truncation for Wireless Transport Block Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems using the Flexible Layer One (FLO) concept in GERAN face challenges in efficiently reporting the number of correctly decoded transport blocks without increasing overhead over the air interface, as the existing 5-bit parameter is insufficient to represent the maximum number of decoded blocks during a reporting period.
Innovation Solution
Adaptive truncation of the least significant bits (LSB) of the binary representation of the number of correctly decoded blocks, allowing for dynamic adjustment of reporting resolution to fit within the fixed 5-bit parameter, and alternative mappings such as non-linear reporting scales to optimize the representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the existing 5-bit parameter is used for reporting, then the overhead over the air interface is minimized, but the parameter becomes insufficient to represent the maximum number of decoded blocks during a reporting period
Solution Approach 1:
The patent changes the interpretation of the fixed 5-bit parameter by dynamically adjusting the mapping between the bit pattern and the reported value based on the maximum number of transport blocks that can be reported in the current configuration. This allows the same physical parameter to represent different ranges of values depending on the reporting context, resolving the contradiction between fixed parameter size and variable reporting requirements
Solution Approach 2:
The patent introduces dynamic adaptation of the reporting scale based on the actual number of transport blocks being reported. The system transitions from a static 5-bit parameter to a dynamically interpreted parameter that adjusts its resolution and mapping based on the current communication conditions, allowing full utilization of the parameter space without increasing overhead
2Adaptability or versatility
If adaptive truncation of least significant bits is applied, then the reporting resolution is dynamically adjusted to fit within the fixed parameter, but the measurement precision is reduced for large numbers of decoded blocks
Solution Approach 1:
The patent applies parameter changes by modifying the bit mapping based on the magnitude of the number being reported. For smaller numbers of decoded blocks, the full 5-bit resolution is maintained. For larger numbers, the system dynamically adjusts the mapping to accommodate the increased range while working within the fixed parameter constraints, accepting reduced precision as a trade-off for extended reporting capability
3Loss of information
If the number of transport blocks to be reported increases, then the information content increases, but the existing fixed parameter structure cannot accommodate the increased information
Solution Approach 1:
The patent makes the existing 5-bit parameter universal by enabling it to serve multiple reporting scenarios with different numbers of transport blocks. Through dynamic mapping and interpretation, the same physical parameter structure can accommodate various reporting requirements without requiring separate parameter sets, thus avoiding increased device complexity while maintaining information completeness
Data Source
AI summary
A method and a device for reporting the number of correctly decoded transport blocks in a wireless system. The maximum number of correctly decoded transport blocks within a reporting period is determined. Then the actual number of correctly decoded transport blocks is determined and cultivated into an indication thereof on the basis of the maximum number. The indication is sent to a network element capable of decoding it for analysis.
