Dynamic Subframe Configuration for LTE Resource Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing LTE systems, dynamic uplink/downlink subframe switching in TDD mode leads to a decrease in resource utilization rate for new User Equipment (UE) during data reception, as they need to adapt to different subframe configurations, affecting the efficiency of data reception.
Innovation Solution
A method and system where the UE determines and receives first and second configuration information for dynamic subframes, allowing it to adapt data reception modes based on different frame structures, thereby improving resource utilization by using subframes as either downlink or special subframes, or both, to enhance flexibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic uplink/downlink subframe switching is implemented in existing LTE systems, then the network transmission rate is improved and time delay is reduced, but the resource utilization rate for new UE during data reception decreases
Solution Approach 1:
The patent implements dynamic uplink/downlink subframe switching by allowing the network to dynamically change subframe configurations between different UL/DL patterns. The network can switch between configuration #0 and configuration5 based on traffic demands, enabling flexible adaptation of resource allocation while maintaining high transmission rates and low latency.
Solution Approach 2:
The patent enables new UE to receive data in both special subframe format and downlink subframe format within the same subframe. By configuring the UE with multiple reception modes and allowing it to adaptively switch between them, the system achieves multi-functionality where a single UE can handle both traditional and dynamic configuration scenarios, thereby improving resource utilization without sacrificing transmission performance.
2Adaptability or versatility
If new UE adapt to different subframe configurations during dynamic switching, then flexibility is improved, but data reception efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the UE with multiple subframe configuration patterns (including both special subframe and downlink subframe formats) before dynamic switching occurs. The network provides advance notification of configuration changes through signaling, allowing the UE to prepare appropriate reception modes in advance, thus maintaining data reception efficiency while adapting to different configurations.
Solution Approach 2:
The patent implements dynamic adaptation mechanisms where the UE can switch between different reception modes based on real-time configuration indications from the network. The system dynamically adjusts the UE's data reception behavior to match the current subframe configuration, ensuring both flexibility and maintained reception efficiency through adaptive resource allocation.
