Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for periodic multi-slot allocations in 5G networks face challenges due to varying data packet sizes, leading to potential resource wastage when data is not available to fill pre-configured resources.
Innovation Solution
A method for network nodes to transmit indicators for unutilized or short resources in periodic multi-slot allocations, allowing for dynamic adjustment of resource allocation by reducing or adding resources as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If periodic multi-slot allocations are pre-configured with fixed resources, then resource allocation is simplified and scheduling overhead is reduced, but resource wastage occurs when data packet sizes vary and data is not available to fill allocated resources
Solution Approach 1:
The patent implements dynamic resource allocation by introducing indicator signaling that allows the network node to dynamically adjust the periodic multi-slot allocation based on actual data availability. The indicator can signal to reduce the allocation by one or more slots when data is not available, transforming the static pre-configured allocation into a dynamically adaptable resource assignment that matches actual traffic conditions.
Solution Approach 2:
The patent changes the allocation parameters (number of slots, time domain resources) based on data packet size and availability. By modifying the allocation parameters dynamically through indicator signaling, the system adapts the resource allocation to match the actual data transmission needs, preventing resource wastage while maintaining simplified scheduling through periodic structures.
2Productivity
If periodic multi-slot allocations are increased to handle large data packets, then system capacity is improved, but network interference increases when resources are not fully utilized
Solution Approach 1:
The patent implements a feedback mechanism where the network node monitors data availability and transmission utilization, then sends indicator signaling to adjust the periodic multi-slot allocation. This feedback loop allows the system to reduce allocation when data is not available (preventing interference) and maintain or increase allocation when data is available (maintaining capacity), thus balancing system capacity with interference reduction.
Solution Approach 2:
The patent makes the resource allocation dynamic by allowing real-time adjustment of the periodic multi-slot allocation based on actual traffic conditions. The indicator signaling enables the system to transition between different allocation states (full allocation, partial allocation, or reduced allocation) to match data availability, thereby preventing network interference from unused resources while maintaining high system capacity when needed.
3Ease of operation
If fixed periodic allocations are used, then scheduling overhead is reduced, but adaptability to varying data demands deteriorates
Solution Approach 1:
The patent combines the simplicity of fixed periodic allocations with dynamic adaptability by introducing indicator signaling. The periodic structure maintains low scheduling overhead, while the indicator mechanism enables dynamic adjustment of the allocation size and timing to match varying data demands, achieving both ease of operation and adaptability.
Solution Approach 2:
The patent creates a universal scheduling framework that can handle both fixed periodic allocations and dynamic adjustments through a single mechanism. The indicator signaling system serves multiple functions: it can signal allocation reduction, maintain allocation, or trigger reallocation, making the system versatile enough to adapt to various data demand patterns while maintaining the simplicity of periodic scheduling.
