Solution Overview

Problem

The existing control resource allocation methods in 5G networks are inflexible and cannot dynamically adjust to meet the changing requirements of PDCCH resources due to fluctuations in the number of active users and traffic in the network.

Innovation Solution

A method for dynamically allocating control resources by identifying resource usage status information for a preset period, determining CORESET time-frequency resources, and adjusting UL/DL control channel element (CCE) patterns based on this information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed CORESET resources are allocated for PDCCH, then resource allocation is simple and stable, but the system cannot adapt to changing traffic conditions and user requirements

Engineering Contradiction:
Improveadaptability to changing traffic conditionsVSAvoidresource allocation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic CORESET resource allocation where the network device adjusts control resource configurations based on real-time traffic conditions and user requirements. The system transitions from static pre-configured resources to dynamic resource allocation, allowing CORESET parameters (time-frequency resources, CCE patterns) to be modified according to changing network states, thereby resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters of CORESET resources including time-frequency resource allocation, CCE pattern configurations, and control channel bandwidth based on traffic conditions. By dynamically adjusting these parameters rather than maintaining fixed configurations, the system achieves adaptability to varying user demands while managing complexity through parameter-based control mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If control resources are increased to meet peak demand, then service quality is improved, but resource waste occurs during low traffic periods

Engineering Contradiction:
Improveservice qualityVSAvoidresource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements periodic evaluation and adjustment of CORESET resource allocation. The network device periodically monitors traffic conditions and user requirements, then adjusts control resource configurations accordingly. This periodic action allows the system to scale resources up during high-demand periods to maintain service quality and scale down during low-demand periods to reduce resource waste, achieving a balance between reliability and efficiency.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system employs feedback mechanisms where the network device continuously monitors traffic conditions, user equipment states, and resource utilization metrics. Based on this feedback information, the system dynamically adjusts CORESET resource allocation to match actual demand, ensuring sufficient resources are allocated during peak periods to maintain service quality while reducing allocations during low-traffic periods to minimize resource waste.

Inventive Principle:
Principle #23Feedback
