Dynamic MAP Message Size Estimation for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In broadband wireless communication systems, the fixed size of MAP messages leads to inefficiencies in resource utilization and allocation, as the number of resource allocation information elements is fixed, limiting the flexibility and efficiency of resource management.
Innovation Solution
A method and apparatus for estimating the size of MAP messages and dynamically allocating bursts based on the estimated size, allowing for flexible resource allocation by evaluating the available burst allocation region and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the MAP message size is fixed, then the structure is simple and easy to implement, but the resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed MAP message size to a variable size that adapts to actual resource allocation needs. The MAP message size is dynamically determined based on the number of mobile stations and their specific resource requirements, allowing the system to optimize resource allocation efficiency while maintaining manageable complexity through algorithmic determination of message size.
2Ease of operation
If the number of resource allocation information elements is fixed, then the processing is simple, but the adaptability to different resource demands deteriorates
Solution Approach 1:
The patent applies parameter changes by making the number of resource allocation information elements variable rather than fixed. The system dynamically adjusts this parameter based on the actual number of mobile stations and their resource requirements, enabling the MAP message to adapt to different network conditions while maintaining processing efficiency through systematic parameter adjustment.
3Adaptability or versatility
If the MAP message size is increased to accommodate more resource allocation information, then the resource allocation flexibility improves, but the overhead increases
Solution Approach 1:
The patent applies parameter changes to optimize the balance between flexibility and overhead by dynamically adjusting the MAP message size parameter. The system determines the appropriate message size based on actual resource allocation needs, ensuring sufficient flexibility for varying resource demands while minimizing unnecessary overhead by avoiding excessive message sizes when fewer resources need allocation.

AI summary
A resource allocation method of a Base Station (BS) in a wireless communication system is provided. The method includes estimating a size of a MAP message, and evaluating a size of an available burst allocation region according to the estimated size of the MAP message and allocating bursts in the evaluated-sized burst allocation region. Accordingly, when a DownLink (DL) subframe is used by being divining into a plurality of regions according to a burst characteristic, a throughput can be improved without waste of resources by estimating a resource amount occupied by a MAP message in the DL subframe.
