WCDMA Transport Format Selection via Priority Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WCDMA mobile communication systems, the existing method of selecting transport formats for data transfer is time-consuming and can cause overload due to the need to search through an extensive table of all allocable transport formats, which hampers data transmission efficiency.
Innovation Solution
The method involves sorting logical channels by priority and transport format indicators by the number of transport blocks, allowing for the selection of transport formats that match the size of data blocks to be transferred, thereby minimizing search time and optimizing data transmission rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing method of selecting transport formats by searching through an extensive table of all allocable transport formats is used, then comprehensive format selection is achieved, but the selection time increases and system overload occurs
Solution Approach 1:
The patent applies preliminary action by pre-sorting transport format indicators according to the number of transport blocks before actual data transfer occurs. This pre-organization allows the system to quickly retrieve appropriate formats during data transfer without performing extensive searches, thus reducing selection time while maintaining comprehensive format availability.
Solution Approach 2:
The patent segments the transport format selection process by dividing formats into different categories based on the number of transport blocks. By organizing formats into segmented groups (e.g., different TBS ranges), the system can directly access relevant segments rather than searching through all formats, significantly reducing the time required for format selection.
2Adaptability or versatility
If the existing method of searching through all allocable transport formats is used, then all possible formats are considered, but system overload occurs
Solution Approach 1:
The patent applies the extraction principle by removing unnecessary transport formats from the search process. By extracting only the relevant formats based on pre-sorted categories matching the data block size, the system avoids processing irrelevant formats, thus reducing system overload while maintaining coverage of all necessary format options.
Solution Approach 2:
The system performs preliminary categorization of transport formats by the number of transport blocks before actual data transfer. This pre-organization enables direct retrieval of appropriate formats without extensive searching, reducing processing overhead and improving data transmission efficiency while maintaining comprehensive format coverage.
3Ease of operation
If transport formats are selected without sorting by data block size, then selection process is simpler, but data transmission rate is reduced
Solution Approach 1:
The patent applies preliminary action by pre-sorting transport format indicators according to the number of transport blocks before actual data transfer. This pre-organization maintains operational simplicity during data transfer while enabling fast retrieval of optimal formats, thus preserving both ease of operation and high data transmission rates.
Solution Approach 2:
The patent implements a dynamic format selection mechanism where the sorting and selection process adapts to the specific data block size requirements. By dynamically selecting formats based on matched categories rather than using a fixed simple selection method, the system optimizes transmission rate while maintaining operational simplicity through automated category matching.

AI summary
Disclosed is a method for selecting transport formats corresponding to transport channels in a wideband code division multiple access mobile communication system. The method includes the steps of sorting a logical channels according to priorities, the logical channels existing between a radio link control layer entity and a medium access control layer entity; sorting transport format indicators indicating the transport formats according to a number of transport blocks for each corresponding transport format; and according to a sequence of the sorted transport format indicators, selecting transport formats supporting transport blocks of a transport format indicator, a number of which is less than or equal to a number of data blocks to be transferred through a logical channel according to each priority; and comparing size of the data blocks to be transferred with sizes of transport blocks of a selected transport format indicator and selecting a transport format indicator having sizes of a transport block identical to sizes of the data blocks to be transferred.
