Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems face challenges due to the short slot length and increased complexity, which can lead to issues like power saving inefficiencies, disproportionate scaling of processing timelines, and higher overhead in managing control channels and RF re-tuning, particularly in Frequency Range 4 (FR4) bands.
Innovation Solution
Implementing dynamic processing timeline adaptation in user equipment, allowing selection between different processing timelines based on monitoring conditions, scheduling conditions, or signaling from the base station, enabling flexible control channel monitoring and scheduling regimes such as per-slot or multi-slot configurations.

Engineering Contradiction Analysis
1Productivity
If high-frequency bands (FR4) are used for wireless communication, then data rates and spectrum efficiency are improved, but slot length becomes very short and processing complexity increases
Solution Approach 1:
The patent implements dynamic processing timeline adaptation where the UE can switch between different processing timelines (first timeline with shorter processing time, second timeline with longer processing time) based on monitoring conditions, scheduling conditions, or base station signaling. This dynamic adjustment allows the system to adapt processing complexity to the specific high-frequency communication scenario, resolving the contradiction between achieving high data rates and managing processing complexity in FR4 bands.
Solution Approach 2:
The patent changes the processing timeline parameters (processing time, monitoring periodicity, scheduling intervals) based on the operating frequency band and communication conditions. By adjusting these parameters dynamically, the system can optimize performance for high-frequency bands while preventing excessive processing complexity, thus resolving the technical contradiction between productivity and device complexity.
2Loss of time
If per-slot control channel monitoring is implemented, then latency is reduced, but power consumption and overhead increase
Solution Approach 1:
The patent enables dynamic switching between per-slot monitoring and multi-slot monitoring modes based on communication conditions. When low latency is critical, per-slot monitoring is activated; when power saving is prioritized, multi-slot monitoring is used. This dynamic approach resolves the contradiction between reducing latency and minimizing power consumption in high-frequency communications.
Solution Approach 2:
The monitoring periodicity parameter is dynamically adjusted based on traffic conditions and latency requirements. The system can change from monitoring every slot to monitoring every N slots, allowing optimization of the trade-off between latency reduction and power consumption in different operational scenarios.
3Adaptability or versatility
If RF re-tuning frequency is increased for high-frequency bands, then spectrum flexibility is improved, but processing overhead and complexity increase
Solution Approach 1:
The patent implements dynamic adaptation of processing timelines that accounts for RF re-tuning requirements. The system can adjust processing schedules to accommodate frequency changes, optimizing the balance between spectrum flexibility and processing overhead in high-frequency bands.
