Terminal Transmission Direction Adaptation for Resource Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, the asymmetrical uplink and downlink traffic volumes often lead to inefficient resource utilization, particularly when downlink traffic is high and uplink resources are underutilized.
Innovation Solution
A terminal determines the transmission direction of a first transmission resource based on the first transmission direction of a configured or scheduled transmission, even if it differs from the network-side device's configuration or if no direction is configured by the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal follows the network-side device's configured transmission direction for a transmission resource, then the transmission direction is stable and predictable, but the resource utilization rate is low when uplink traffic volume is greater than downlink traffic volume
Solution Approach 1:
The patent applies the dynamics principle by enabling the transmission direction of a transmission resource to be dynamically determined based on the actual traffic volume of the terminal. Instead of being fixed by network configuration, the transmission direction (uplink or downlink) is adaptively selected according to real-time traffic conditions, allowing the system to respond to changing load requirements and optimize resource utilization.
Solution Approach 2:
The patent applies parameter changes by modifying the transmission direction parameter based on traffic volume thresholds. When the terminal's uplink traffic volume exceeds a threshold, the transmission direction is changed from downlink to uplink, and vice versa. This dynamic parameter adjustment allows the system to adapt to varying traffic patterns and optimize resource allocation efficiency.
2Productivity
If the transmission direction is flexibly adjusted based on actual traffic requirements, then the resource utilization rate is improved, but the complexity of determining transmission direction increases
Solution Approach 1:
The patent applies the self-service principle by enabling the terminal to autonomously determine its own transmission direction based on its traffic volume. The terminal independently compares its uplink and downlink traffic volumes and selects the appropriate transmission direction without requiring complex network-side coordination or additional signaling, simplifying the overall system operation while improving resource utilization.
3Productivity
If downlink resources are allocated based on network configuration, then the network can control resource allocation, but the uplink resources remain idle when uplink traffic volume is high
Solution Approach 1:
The patent applies the feedback principle by implementing a mechanism where the terminal continuously monitors its traffic volume and uses this feedback information to adjust the transmission direction of allocated resources. The terminal compares actual traffic conditions with the configured transmission direction and switches directions when necessary, ensuring that resources are always allocated according to current demand while maintaining network control through the feedback loop.
