Periodic Resource Switching Configuration for 5G Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face inefficiencies in managing periodic resource configurations for uplink and downlink channels, leading to suboptimal data transmission due to fixed scheduling and increased signaling overhead when switching between different configurations.
Innovation Solution
A method where a base station transmits first and second configurations of periodic resources to a UE, along with a metric for switching, allowing the UE to automatically adjust between configurations based on timers, buffer status reports, power headroom reports, beam changes, or bandwidth parts without explicit signaling, thereby optimizing resource allocation and reducing overhead.

Engineering Contradiction Analysis
1Ease of operation
If fixed scheduling configuration is used for periodic resources, then device complexity is reduced and ease of operation is improved, but data transmission efficiency deteriorates and adaptability worsens
Solution Approach 1:
The patent implements dynamic switching between multiple periodic resource configurations (first and second configurations) based on real-time metrics such as signal quality, scheduling requirements, and traffic patterns. This allows the system to adapt resource allocation dynamically rather than using fixed scheduling, thereby improving data transmission efficiency while maintaining operational simplicity through automated metric-based decision-making.
Solution Approach 2:
The system changes key parameters of periodic resource configurations including periodicity, time offset, frequency offset, and resource block allocation based on evaluated metrics. By adjusting these parameters dynamically according to network conditions, the system optimizes data transmission efficiency while the base station automates the parameter selection process to maintain ease of operation.
2Adaptability or versatility
If switching between different periodic resource configurations is enabled, then adaptability and data transmission efficiency are improved, but signaling overhead increases and device complexity worsens
Solution Approach 1:
The system employs feedback mechanisms where the base station evaluates metrics related to signal quality, scheduling requirements, and traffic patterns, then automatically determines when and how to switch between configurations. This feedback-driven approach enables adaptability while minimizing signaling overhead by only transmitting configuration switches when metric-based conditions are met, rather than continuous signaling.
Solution Approach 2:
The UE is configured with multiple periodic resource configurations and the metric evaluation criteria in advance, enabling it to autonomously determine when to switch between configurations based on local measurements of signal quality and traffic patterns. This self-service capability reduces signaling overhead by eliminating the need for base station-directed switching commands for every configuration change.
3Adaptability or versatility
If multiple periodic resource configurations are maintained, then adaptability is improved, but device complexity and memory requirements worsen
Solution Approach 1:
The system segments the periodic resource configuration space into distinct first and second configurations, each optimized for specific traffic patterns or channel conditions. By dividing the configuration options into manageable segments rather than maintaining a large monolithic set of configurations, the system achieves adaptability while keeping device complexity manageable through structured organization of configuration parameters.

AI summary
A UE may receive, from a base station, a first and second configurations of first and second periodic resources, receive, from the base station, a metric for switching between the first and second configurations, and switching from the first configuration to the second configuration based on the metric received from the base station. The first and second configurations may be CG of uplink resources for uplink channels. The first and second configurations may indicate SPS resources for downlink channels. The base station may determine the metric based on at least one measurement of signal at the base station or scheduling requirements.
