Dynamic Frame Configuration for Channel Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently coordinating channel resources between frame-based scheduled and contention-based systems, especially when they have asymmetric traffic loads, leading to resource waste and performance degradation due to fixed frame configurations.
Innovation Solution
A method and network node that dynamically adjust frame configurations based on traffic status ratios between frame-based scheduled and contention-based transmissions, applying a schedule-based or contention-based frame configuration probabilistically to optimize channel use and minimize collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed frame configuration is used for frame-based scheduled transmission, then the system structure is simple and stable, but resource utilization deteriorates under asymmetric traffic loads
Solution Approach 1:
The patent applies dynamics by making the frame configuration adaptive rather than fixed. The base station dynamically adjusts the frame configuration based on detected traffic statuses of both frame-based scheduled transmission and contention-based transmission. This allows the system to transition between different frame configuration states (e.g., different proportions of schedule-based frames vs. contention-based frames) to optimize resource utilization under varying traffic conditions while maintaining system stability through controlled adaptation.
2Productivity
If the channel is continuously occupied by frame-based scheduled transmission, then the frame-based system achieves high throughput, but contention-based transmission cannot access the channel leading to unfairness
Solution Approach 1:
The patent implements periodic action by introducing contention-based transmission opportunities at regular intervals within the frame structure. Specifically, certain frames are configured as contention-based frames where the frame-based scheduled transmission is disabled or shares the channel in a contention-based manner. This periodic allocation ensures that contention-based systems get fair access to the channel while maintaining high throughput for frame-based transmissions during schedule-based frames, achieving a balance between the two systems.
3Adaptability or versatility
If the frame configuration is changed to optimize for contention-based access, then channel sharing fairness improves, but frame-based scheduled transmission performance deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting the proportion and distribution of schedule-based frames versus contention-based frames in the frame configuration. Instead of using a fixed configuration, the base station detects traffic statuses and modifies frame configuration parameters (such as the ratio of schedule-based frames to total frames) to optimize both frame-based transmission efficiency and channel sharing fairness. This allows the system to adapt parameters dynamically based on actual traffic conditions.

AI summary
The present disclosure provides a method (700) and a network node (800) for coordination of channel resources between a first transmission and a second transmission sharing a common channel. The method (700) includes: detecting (S710) a first traffic status of the first transmission and a second traffic status of the second transmission during a time period; and applying (S720) one of a first frame configuration and a second frame configuration to a frame based on a probability value dependent on the first traffic status and the second traffic status. When the first frame configuration is applied to the frame, the first transmission uses the channel within the duration of the frame regardless of whether the second transmission is using the channel. When the second frame configuration is applied to the frame, the first transmission is disabled or shares the channel with the second transmission in a contention-based manner within the duration of the frame.
