Dynamic Bandwidth Allocation for Wireless Communication Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The allocation of resource units in wireless communication systems, particularly with OFDMA technology, is complex due to varying operating parameters of remote devices and interference conditions, making it difficult to achieve efficient and dynamic bandwidth allocation.
Innovation Solution
A wireless communication apparatus with a dynamic transmission bandwidth allocation mechanism that retrieves interference and transmission ability information, sets a predetermined bandwidth range, allocates devices based on this data, and adjusts the range if necessary to satisfy resource unit allocation criteria, ensuring efficient allocation of remote devices to resource units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If resource units are allocated based on operating parameters of remote devices and interference conditions, then allocation accuracy is improved, but allocation complexity increases
Solution Approach 1:
The frequency band is divided into multiple resource units with different sizes, allowing granular allocation to different remote devices based on their specific needs and conditions. This segmentation enables precise matching of resources to device requirements without managing the entire bandwidth as a single unit, thus improving allocation accuracy while keeping complexity manageable through modular resource management.
Solution Approach 2:
The patent implements a dynamic allocation mechanism where the bandwidth range is adjusted based on allocation results and interference conditions. The system retrieves interference information and transmission ability information, performs allocation, evaluates the results, and dynamically modifies the bandwidth range for subsequent allocations. This dynamic approach allows the system to adapt to changing conditions and improve accuracy over time without requiring overly complex static configurations.
2Speed
If bandwidth allocation is performed without dynamic adjustment, then allocation speed is maintained, but adaptability to interference conditions deteriorates
Solution Approach 1:
The system retrieves interference information and transmission ability information before performing bandwidth allocation. By gathering necessary information in advance, the system prepares for efficient allocation without requiring complex real-time adjustments during the allocation process itself. This preliminary action enables both speed and adaptability by pre-processing data that will guide the allocation decision.
Solution Approach 2:
The patent implements a feedback mechanism where allocation results are evaluated against allocation criteria, and the bandwidth range is dynamically adjusted based on this evaluation. The system determines whether the allocation result satisfies resource unit allocation criteria, and if not, shrinks the bandwidth range and re-performs allocation. This feedback loop enables the system to adapt to interference conditions while maintaining efficient allocation through iterative refinement rather than complex single-step decisions.

AI summary
The present disclosure discloses a dynamic transmission bandwidth allocation method having dynamic transmission bandwidth allocation mechanism used in a wireless communication apparatus is provided that includes the steps outlined below. Interference information and transmission ability information of remote wireless communication apparatuses is retrieved. A predetermined transmission bandwidth range that includes resource units is set. The remote wireless communication apparatuses are allocated in the predetermined transmission bandwidth range to generate an allocation result. Whether the allocation result satisfies resource unit allocation criteria is determined. When the allocation result does not satisfy the resource unit allocation criteria, the predetermined transmission bandwidth range is shrunk to another allocatable transmission bandwidth range to determine whether the allocation result satisfies the resource unit allocation criteria. When the allocation result satisfies the resource unit allocation criteria, the remote wireless communication apparatuses are allocated according to the allocation result to perform communication thereto through a communication circuit.
