Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing methods face challenges in efficiently transmitting and receiving data blocks due to limitations in configuring and utilizing combination information for data block sizes, particularly in point-to-multipoint services, leading to inefficiencies in data traffic transmission.
Innovation Solution
A method is introduced where a mobile terminal receives data block size combination information from the network, defines default combinations if necessary, and uses this information to efficiently map higher-level channels to lower-level channels, allowing for efficient data block transmission and reception by internally configuring combination information for data block sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile terminal receives and internally configures data block size combination information from the network, then data block transmission efficiency is improved, but device complexity increases due to the need to manage multiple data block size combinations and channel mappings
Solution Approach 1:
The mobile terminal pre-configures multiple data block size combinations and their corresponding channel mappings before actual data transmission occurs. This preliminary configuration allows the terminal to efficiently handle data blocks of varying sizes without complex real-time calculations, thereby improving transmission efficiency while managing complexity through pre-computed configurations
Solution Approach 2:
The system dynamically selects and switches between different data block size combinations based on transmission conditions. By changing the parameter of data block size according to network conditions and service requirements, the system optimizes transmission efficiency for point-to-multipoint services while the terminal manages multiple configurations through standardized parameter sets
2Reliability
If the mobile terminal defines default data block size combinations when no combination information is received from the network, then transmission reliability is improved, but loss of information increases due to potential mismatches between assumed and actual transmission parameters
Solution Approach 1:
The mobile terminal first attempts to receive data block size combination information from the network. If received, this feedback information is used to configure the terminal's data block handling parameters. If not received, the terminal falls back to pre-defined default combinations. This feedback mechanism ensures transmission reliability by using actual network parameters when available, while defaults provide a safety net that minimizes information loss
Solution Approach 2:
The system prepares default data block size combinations in advance as a cushion against potential parameter mismatches. These defaults are designed to be conservative and compatible with various transmission conditions, providing a safety buffer that prevents complete failure if network information is unavailable or incorrect, thereby maintaining reliability while minimizing information loss
3Adaptability or versatility
If the mobile terminal internally configures data block sizes for point-to-multipoint services, then adaptability is improved, but device complexity increases due to the need to manage multiple channel mappings and data block configurations
Solution Approach 1:
The mobile terminal is configured to handle multiple data block size combinations and their corresponding channel mappings through a unified configuration management mechanism. This universal approach allows the terminal to adapt to various point-to-multipoint service requirements by selecting appropriate pre-configured combinations, thereby achieving versatility without proportionally increasing complexity through standardized multi-functional support
Solution Approach 2:
The configuration management is segmented into discrete data block size combinations, each with predefined channel mappings. This segmentation allows the terminal to manage complexity by handling each combination as a separate, pre-processed unit rather than managing all possible configurations simultaneously. The segmented approach enables adaptability to different service types while keeping individual configuration units simple and manageable
