Solution Overview

Problem

The introduction of services like extended reality (XR) and ultra-reliable low-latency communications (URLLC) into communications systems results in a mismatch between the configuration of access network devices and the transmission requirements of target data, leading to inadequate resource allocation and failure to meet service demands.

Innovation Solution

A wireless communication method where a communications device transmits first information to an access network device, including details about target data such as static and dynamic features, enabling the access network device to optimize its configuration and resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the access network device performs configuration at a terminal device granularity, then the configuration covers all services for the terminal, but the configuration cannot meet the specific transmission requirements of different service types (XR, URLLC)

Engineering Contradiction:
Improveservice-specific configuration adaptabilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the configuration into two levels: terminal-level configuration (common parameters) and service-level configuration (specific parameters). The network device receives service-specific information from the core network device and applies it to configure resources for specific services like XR and URLLC, while maintaining terminal-level configuration for common settings. This segmentation enables service-specific adaptation without completely redesigning the terminal configuration system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by allowing different configuration parameters to have different granularities for different services. For example, while terminal-level configuration uses a coarse granularity suitable for all services, service-level configuration uses fine granularity to meet specific requirements of XR (low latency, high bandwidth) and URLLC (ultra-reliable, low latency) services. This enables each service to receive appropriately tailored configuration.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the access network device uses general configuration for all services, then the configuration is simple to manage, but the transmission requirements of target data for specific services cannot be met

Engineering Contradiction:
Improveconfiguration management easeVSAvoidservice requirement fulfillment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary action by having the core network device provide service-specific information to the access network device in advance, before actual data transmission begins. This allows the access network device to pre-configure resources and parameters optimized for specific services like XR and URLLC, ensuring that when data transmission occurs, the configuration is already in place to meet reliability requirements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces the core network device as an intermediary that bridges the gap between general terminal configuration and service-specific requirements. The core network device provides service-specific information (such as service type, QoS requirements) to the access network device, which then uses this information to configure appropriate parameters. This intermediary mechanism enables service-specific configuration without requiring complex direct configuration management at the terminal level.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the access network device allocates resources at terminal granularity, then resource allocation is straightforward, but resource allocation efficiency is low due to mismatch with actual transmission requirements

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making resource allocation adaptive rather than static. The access network device dynamically adjusts resource allocation based on service-specific information received from the core network device. For example, XR services may receive different resource allocations compared to URLLC services, and these allocations can be adjusted in real-time based on actual transmission requirements, improving overall resource allocation efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes by modifying configuration parameters based on service type. The access network device receives service-specific information and changes parameters such as bandwidth allocation, latency constraints, and priority levels according to the specific service requirements. This enables efficient resource allocation tailored to each service's actual transmission needs rather than using a one-size-fits-all approach.

Inventive Principle:
Principle #35Parameter changes
