Flexible Duplex Signaling for Real-Time UE Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks lack sufficient information for networks to make optimal scheduling decisions for flexible duplex operations, relying on static UE capabilities and measurements that do not accurately reflect a UE's actual performance in varying conditions.
Innovation Solution
UEs evaluate their actual ability to operate in flexible duplex mode and dynamically signal this information to the network, including key parameters such as Tx power, receiver performance, and self-interference mitigation, enabling the network to make informed scheduling decisions.

Engineering Contradiction Analysis
1Productivity
If static UE capabilities and measurements are used for scheduling decisions, then the system is simple to operate, but the scheduling optimality and data rates are limited
Solution Approach 1:
The patent implements dynamic flexible duplex capability signaling where the UE evaluates its actual ability to operate in flexible duplex mode based on prevailing signal and operating conditions, and provides ability information to the network dynamically rather than using static capabilities. This allows the scheduling to adapt to changing conditions and achieve higher data rates.
Solution Approach 2:
The patent changes the parameter being signaled from static UE capabilities to dynamic ability information that reflects the UE's actual performance in current conditions. The UE evaluates parameters such as self-interference mitigation performance, receiver performance, and transmitter performance, and signals this ability information to enable optimized scheduling decisions.
2Productivity
If static minimum requirements are used for UE capabilities, then the system is reliable and predictable, but the network cannot achieve optimal scheduling decisions
Solution Approach 1:
The patent introduces feedback mechanisms where the UE continuously evaluates its actual ability to operate in flexible duplex mode based on prevailing conditions and signals this ability information back to the network. This feedback loop enables the network to make informed scheduling decisions that optimize productivity while maintaining reliability through the UE's self-evaluation of its capabilities.
Solution Approach 2:
The patent implements preliminary evaluation where the UE assesses its flexible duplex ability before actual operation based on current signal and operating conditions. By evaluating capabilities in advance and signaling this information to the network, the UE enables the network to make optimal scheduling decisions without compromising reliability.
3Productivity
If the network uses flexible duplex mode with one TDD carrier, then frequency resources are utilized more efficiently, but the complexity of managing non-overlapping resources increases
Solution Approach 1:
The patent implements self-service where the UE autonomously evaluates its own ability to operate in flexible duplex mode and signals this information to the network. This self-evaluation mechanism reduces the network's burden in managing complex non-overlapping resources, as the UE provides accurate capability information that simplifies the network's resource allocation decisions.
