Engineering Contradiction Analysis
1Productivity
If traditional fixed scheduling cycles are used for uplink and downlink communications, then system simplicity is maintained, but communication efficiency deteriorates due to misalignment with periodic multimedia traffic patterns
Solution Approach 1:
The patent implements dynamic scheduling cycles that adapt to the periodicity of multimedia traffic. The network entity and UE determine scheduling cycles based on detected traffic patterns, allowing the system to transition from fixed to flexible scheduling. This enables alignment with periodic traffic bursts while maintaining system manageability through automated detection and adaptation mechanisms.
Solution Approach 2:
The patent changes the scheduling cycle parameter from a fixed value to a variable that adapts to traffic conditions. By monitoring multimedia traffic periodicity and adjusting the scheduling cycle accordingly, the system optimizes resource allocation. The network entity can modify scheduling parameters dynamically based on observed traffic patterns, improving efficiency without requiring complete system redesign.
2Productivity
If scheduling cycles are aligned with periodic multimedia traffic patterns, then resource utilization improves, but interference increases due to concurrent uplink and downlink transmissions
Solution Approach 1:
The patent segments the scheduling into separate uplink and downlink cycles to prevent interference. By configuring different scheduling cycles for UL and DL communications, the system ensures that transmissions do not occur simultaneously in conflicting directions. This segmentation allows independent optimization of each direction while avoiding the harmful effects of misaligned concurrent transmissions.
Solution Approach 2:
The patent implements periodic scheduling actions that are synchronized with multimedia traffic patterns. By establishing regular, predictable scheduling cycles for both uplink and downlink that are aligned with traffic periodicity, the system creates structured transmission windows. This periodic structure reduces random interference while maintaining high resource utilization during active traffic periods.
3Object-generated harmful factors
If separate uplink and downlink scheduling cycles are implemented, then interference is reduced, but scheduling complexity increases
Solution Approach 1:
The patent implements a universal scheduling mechanism that handles both uplink and downlink through a common framework. The network entity uses the same traffic detection and cycle determination process for both directions, applying multi-functional scheduling logic. This approach reduces complexity by avoiding separate independent scheduling systems while still achieving the interference reduction benefits of separate UL/DL cycles.
