Dynamic TDD Configuration Selection for Multi-Operator Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems, particularly in multiple operator sharing scenarios, lack a mechanism to dynamically select Time Division Duplex (TDD) configurations that ensure fairness and compliance with Service Level Agreements (SLAs) regarding the allocation of uplink and downlink transmission resources, leading to uncertainty in fulfilling quality of service requirements.
Innovation Solution
A method and device that dynamically or semi-statically select TDD configurations based on sharing parameters defined by SLAs, allocating specific subframes and transmission slots to operators in a deterministic manner, considering the number of active user equipment and service level agreements, to ensure fair and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional FDD approaches are used to guarantee SLA fulfillment over a certain time window, then quality of service requirements are met, but resource allocation flexibility and adaptability to changing traffic conditions are reduced
Solution Approach 1:
The patent implements dynamic TDD configuration selection that adapts to changing traffic conditions while maintaining SLA compliance. The system dynamically adjusts uplink-downlink configuration based on real-time traffic demand and operator sharing agreements, transforming the static resource allocation into a dynamic process that responds to changing conditions while ensuring QoS requirements are met through continuous monitoring and adjustment
2Device complexity
If static TDD configuration is used for resource allocation, then implementation complexity is reduced, but the ability to comply with SLAs regarding fairness between operators is compromised
Solution Approach 1:
The patent changes the TDD configuration parameters (uplink-downlink subframe allocation) based on operator sharing agreements and traffic conditions. By dynamically adjusting these parameters while considering SLA-defined fairness requirements, the system achieves both SLA compliance and operational efficiency without requiring overly complex management mechanisms
3Productivity
If dynamic TDD configuration selection is implemented to improve resource utilization, then productivity and resource efficiency are enhanced, but system complexity and control overhead increase
Solution Approach 1:
The patent employs feedback mechanisms where the system monitors traffic conditions, SLA compliance status, and resource utilization metrics, then uses this feedback to dynamically adjust TDD configurations. This closed-loop control approach enables efficient resource utilization while keeping complexity manageable through rule-based decision making and automated adjustments
