Control Channel Format Identification for EUTRA Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the EUTRA radio system, there is a need for an efficient method to transmit and receive control information for allocating resources between base stations and mobile stations, which is currently not adequately addressed.
Innovation Solution
A base station device and mobile station device that utilize a control information transmission channel with identification information to identify the format of the control information transmission channel, allowing for efficient transmission and reception of control information, including group identification and predetermined formatting based on radio resource positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If control information is transmitted without format identification, then transmission simplicity is maintained, but the mobile station cannot correctly interpret the control information format
Solution Approach 1:
The patent introduces identification information as an intermediary element that mediates between the control information transmission channel and the mobile station. This identification information enables the mobile station to correctly interpret the control information format without requiring complex protocol negotiations or predefined assumptions about the channel format.
2Adaptability or versatility
If multiple control information formats are supported, then system adaptability improves, but determining the correct format becomes more difficult
Solution Approach 1:
The patent uses identification information as a distinctive marker (analogous to color changes) that clearly indicates which control information format is being used. This allows the mobile station to quickly and accurately detect the format without having to analyze the complex structure of the control information itself or make difficult decisions among multiple possible formats.
3Productivity
If group identification information is included, then mobile station group management efficiency improves, but information transmission overhead increases
Solution Approach 1:
The identification information serves multiple functions simultaneously: it identifies the control information format, indicates the target mobile station group, and enables efficient resource allocation. This multi-functionality reduces the need for separate signaling messages, thereby minimizing the overall information transmission overhead while achieving efficient group management.
