Dynamic Contention-Based Resource Allocation in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing contention-based resources, leading to increased latency and signaling overhead due to static resource allocation and lack of dynamic updates, which hinders the ability to accommodate high data traffic and multiple connected devices effectively.
Innovation Solution
A method and apparatus for dynamically allocating contention-based resources, where a terminal receives configuration information for a contention-based resource region from a network node, transmits a preamble and message based on this information, and requests modifications when necessary, allowing for real-time updates and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static resource allocation is used for contention-based resources, then device complexity is reduced and ease of operation is improved, but latency increases and productivity decreases due to inability to adapt to changing traffic conditions
Solution Approach 1:
The patent implements dynamic resource allocation for contention-based resources by allowing the network to update configuration information (such as resource region, time, frequency, and resource block assignments) in real-time based on traffic conditions. This enables the system to adapt resource allocation dynamically while maintaining operational simplicity through automated network-controlled updates.
Solution Approach 2:
The system employs feedback mechanisms where the network monitors traffic conditions and device requests, then adjusts contention-based resource configurations accordingly. This feedback loop allows the system to reduce latency by allocating resources proactively based on observed traffic patterns and device needs, rather than using static pre-allocated resources.
2Loss of energy
If static resource allocation is used for contention-based resources, then signaling overhead is reduced, but productivity decreases due to inability to accommodate increased data traffic and device connections
Solution Approach 1:
The patent enables dynamic adjustment of contention-based resource configurations to match actual traffic demands. The network can update resource allocations (time, frequency, resource blocks) based on current system load and traffic conditions, thereby increasing productivity and capacity to handle more devices and data without proportionally increasing signaling overhead.
Solution Approach 2:
The system changes key parameters of contention-based resources (resource region, time allocation, frequency allocation, resource block assignments) dynamically based on traffic conditions. This allows the system to optimize resource utilization and accommodate increased data traffic and device connections efficiently, improving productivity while managing signaling overhead through targeted parameter updates.
3Productivity
If dynamic allocation of contention-based resources is implemented, then latency is reduced and productivity is improved, but device complexity increases and signaling overhead increases
Solution Approach 1:
The patent implements a system where the network automatically manages dynamic resource allocation without requiring complex device-side decision-making. Devices simply receive configuration information from the network and use the allocated resources, allowing the network to handle the complexity of dynamic allocation while keeping device implementation relatively simple.
Solution Approach 2:
The network acts as an intermediary that manages the complexity of dynamic resource allocation. It processes traffic conditions, determines optimal resource assignments, and communicates configuration information to devices. This intermediary approach allows dynamic resource allocation to improve productivity while containing device complexity, as the network centralizes the complex decision-making logic.
4Adaptability or versatility
If dynamic updates of configuration information are implemented, then adaptability is improved and productivity increases, but signaling overhead increases
Solution Approach 1:
The patent implements dynamic configuration updates for contention-based resources, allowing the system to adapt to changing traffic conditions and device needs. The network can update resource allocations (time, frequency, resource blocks) dynamically, improving adaptability while managing signaling overhead through efficient update mechanisms.
Solution Approach 2:
The system dynamically changes configuration parameters (resource region, time allocation, frequency allocation, resource block assignments) based on traffic conditions and device requests. This enables the system to maintain high adaptability to accommodate diverse traffic patterns and device requirements while optimizing signaling overhead by updating only necessary parameters.
