Variable Random Access Message Format for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing random access procedure in communication systems using higher frequency bands faces inefficiencies due to fixed message formats, which hinder effective communication between terminals and base stations, particularly in identifying message formats and sizes.
Innovation Solution
The proposed method involves a variable message format in the random access procedure, where terminals transmit messages with fields indicating the message format, size, and content, allowing base stations to identify and respond accordingly, using common information for resource allocation based on terminal identifier sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed message formats are used in the random access procedure, then the system structure is simple and easy to implement, but the communication efficiency deteriorates and the system cannot adapt to different terminal identifier sizes and information types
Solution Approach 1:
The patent applies dynamics by making the message format variable rather than fixed. The uplink message format is dynamically adjusted based on the terminal identifier size and information type, allowing the system to adapt to different conditions while maintaining a structured framework through format indication fields.
Solution Approach 2:
The patent changes the parameter of message format from fixed to variable. By introducing format indication fields that specify message structure based on terminal identifier size and information type, the system can modify message parameters dynamically while maintaining systematic control through predefined format options.
2Productivity
If variable message formats are used in the random access procedure, then the communication efficiency is improved and the system can adapt to different terminal identifier sizes, but the system complexity increases
Solution Approach 1:
The patent segments the message structure into distinct components with format indication fields that specify different parts of the message. This segmentation allows the system to process variable formats by breaking them down into manageable segments defined by the format indicators, reducing processing complexity while maintaining versatility.
Solution Approach 2:
The patent uses format indication fields as intermediaries between the variable message content and the fixed processing framework. These indicator fields act as mediators that translate variable message formats into structured processing steps, improving efficiency while managing system complexity through standardized indication mechanisms.
3Adaptability or versatility
If the base station must identify variable message formats, then the message flexibility is improved, but the base station's processing complexity increases
Solution Approach 1:
The patent applies preliminary action by including format indication fields in the message structure that pre-specify the message format before the base station processes it. This preliminary indication of the format allows the base station to quickly identify and adapt to the correct processing mode without complex analysis, reducing identification difficulty while maintaining flexibility.
Solution Approach 2:
The patent inverts the traditional approach by having the terminal indicate the message format rather than the base station determining it through complex analysis. This inversion simplifies the base station's task by receiving explicit format information from the terminal, making format identification easier while preserving message flexibility.
