Group-Based Radio Resource Allocation for MTC Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MTC management methods require individual connection requests from devices, leading to increased control signals and inefficient connection processes, resulting in denied connections for a large number of devices and degraded reception performance due to unnecessary computation in base station processing.
Innovation Solution
A wireless communication system where MTC devices are grouped based on common application data formats, with a common radio resource allocated to each group, allowing for collective access requests and resource allocation, reducing unnecessary computation and improving connection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual connection requests are processed for each MTC device, then connection management is performed individually, but the number of control signals increases enormously and connection efficiency deteriorates
Solution Approach 1:
The patent merges multiple individual connection requests into a single group-based request. MTC devices are divided into groups based on their data transmission characteristics, and each group performs collective connection establishment with the base station, thereby reducing the total number of control signals and improving connection efficiency
Solution Approach 2:
The patent segments MTC devices into different groups based on their application data formats and transmission characteristics. This segmentation allows the base station to handle each group with appropriate resource allocation strategies, managing diversity while maintaining efficiency
2Manufacturing precision
If individual resource allocation is performed for each MTC device, then resource allocation is precise, but the processing complexity and computation time increase
Solution Approach 1:
The patent combines resource allocation for multiple MTC devices into group-level allocation. The base station allocates radio resources to groups rather than individual devices, reducing processing complexity while maintaining adequate resource distribution through group-based management
Solution Approach 2:
The patent changes the allocation parameter from individual device identifiers to group identifiers. By using group-based resource allocation parameters, the base station reduces the dimensionality of the allocation problem, simplifying processing while maintaining resource distribution effectiveness
3Productivity
If standardized group-based resource allocation is implemented, then control signals are reduced and connection efficiency improves, but individual device customization is limited
Solution Approach 1:
The patent segments MTC devices into groups based on their data transmission characteristics and application requirements. This segmentation enables standardized group-based resource allocation that improves efficiency, while still allowing individual device needs to be addressed through appropriate group classification and characteristics
Data Source
AI summary
A wireless communication system is provided in which a plurality of MTC devices can connect to a base station device efficiently. Each of MTC devices in group A that transmits data to the base station device using a predetermined application format is allocated first radio resource common in group A. The MTC device transmits an access request signal to the base station device using the first radio resource. The base station device receives the request signal from the MTC device. The base station device allocates second radio resource common in group A to the MTC device. The MTC device transmits data to the base station device using the second radio resource.
