Dynamic DCI Resource Reconfiguration for TDD to Full Duplex Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges with transmission interruptions and inefficient resource utilization in Time Division Duplex (TDD) mode when switching to full duplex mode, leading to unavailable repetition resources and suboptimal transmission efficiency.
Innovation Solution
The method involves transmitting first and second Downlink Control Information (DCI) to user equipment, where the second DCI includes indication information or a specific format to determine resources for remaining repetitions of a target Transport Block, allowing for dynamic resource configuration and efficient HARQ process scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time/frequency domain transmission resources for repetitions are configured at once through DCI, then the transmission resources are predetermined, but the repetitions may be interrupted or abundant uplink/downlink transmission resources cannot be utilized
Solution Approach 1:
The patent applies dynamics by enabling dynamic reconfiguration of repetition resources through a second DCI message. The network device can update time-frequency resources for remaining repetitions after initial configuration, allowing the system to adapt to changing network conditions and mode switches (TDD to full duplex), thereby preventing transmission interruptions while maintaining high transmission efficiency.
2Device complexity
If resources are configured statically before mode switching, then the configuration is simple, but resources become unavailable after switching from TDD to full duplex mode
Solution Approach 1:
The patent applies preliminary action by configuring initial repetition resources through first DCI before mode switching occurs. This preliminary configuration ensures that user equipment has valid resources ready, and if mode switching makes these resources unavailable, a second DCI can provide updated resource allocations, thus maintaining both simplicity and adaptability.
Solution Approach 2:
The patent applies parameter changes by allowing the network device to modify resource allocation parameters through the second DCI after mode switching. This enables the system to adjust time-frequency resources to match the new full duplex mode requirements, ensuring resource availability while maintaining a relatively simple initial configuration process.
3Ease of operation
If repetition resources are fixed through initial DCI, then the scheduling is simple, but transmission interruptions occur when resources become unavailable
Solution Approach 1:
The patent applies feedback by implementing a two-stage DCI mechanism where the network device first provides initial resource configuration, then monitors resource availability and transmits a second DCI to reconfigure resources if needed. This feedback loop ensures transmission reliability while maintaining scheduling simplicity through automated resource management.
