Dynamic Carrier Channel Allocation for Wireless Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in bandwidth allocation, particularly when multiple carriers are used, leading to increased interference and resource consumption, especially in scenarios where not all carriers are utilized efficiently, affecting peak rates and system capacity.
Innovation Solution
A method for dynamically allocating communication bandwidth by evaluating current load and priority across multiple carrier channels, allowing terminals to request changes in bandwidth, and allocating new carrier channels to optimize resource usage without increasing minimum resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple carrier channels are used for data transmission, then peak data rates are increased, but resource consumption and interference increase
Solution Approach 1:
The system dynamically adjusts the number of active carrier channels based on real-time buffer status and traffic demands. Terminals can activate or deactivate carriers as needed, transitioning from a static multi-carrier configuration to a dynamic one that adapts to current data transmission needs, thereby improving peak rates only when necessary while reducing resource consumption during low-traffic periods
Solution Approach 2:
The invention changes the operational parameters of carrier channels by introducing buffer-status-dependent activation and deactivation mechanisms. The number of active carriers becomes a variable parameter that changes based on traffic conditions, allowing the system to optimize between peak data rate achievement and resource consumption minimization by adjusting carrier activation states
2Productivity
If multiple carrier channels are allocated to terminals, then system capacity is improved, but minimum resource consumption increases
Solution Approach 1:
The system implements periodic buffer status reporting and carrier activation/deactivation cycles. Instead of maintaining continuous multi-carrier allocation, the system periodically assesses buffer status and adjusts carrier activation accordingly, creating a rhythmic pattern of resource utilization that reduces minimum resource consumption while preserving system capacity when needed
Solution Approach 2:
The invention extracts unnecessary carrier allocations by deactivating carriers when buffers are empty or traffic demands are low. The system selectively removes (takes out) active carrier channels from the system configuration when they are not needed for data transmission, thereby reducing minimum resource consumption while maintaining the capability to restore system capacity when traffic increases
3Reliability
If carriers are continuously allocated to terminals, then data transmission reliability is improved, but resource efficiency deteriorates
Solution Approach 1:
The system implements feedback mechanisms where terminals report buffer status to the network, and the network responds by adjusting carrier allocation. This closed-loop feedback ensures that carriers are allocated reliably when data is present in buffers while efficiently releasing carriers when buffers are empty, thereby maintaining transmission reliability without sacrificing resource efficiency
Solution Approach 2:
Terminals autonomously monitor their own buffer status and trigger carrier activation or deactivation requests based on their data transmission needs. This self-service approach allows terminals to manage their own resource allocation, ensuring reliable transmission when needed while improving overall resource efficiency by preventing unnecessary carrier occupation when no data is pending

AI summary
The present invention relates to a method for allocating communication bandwidth between a first terminal of a plurality of terminals and a network device. Wireless communication between the first plurality of terminals and the network device is carried out using a plurality of carrier channels. The communication defines a first bandwidth. The method comprises the steps of receiving the request for change of bandwidth from the first terminal, evaluating current load on carrier channels in use by the first terminal, evaluating priority between all terminals using the carrier channels currently in use by the first terminal, evaluating capacity of all carrier channels available to the first terminal, and allocating a second bandwidth between the network device and the first terminal by allocating a new number of carrier channels. The present invention further relates to a network device and a device for communication.
