Solution Overview

Problem

Existing resource scheduling methods in wireless communications systems are inadequate for handling diverse service types, leading to reduced service processing efficiency when user equipment (UE) needs to handle multiple types of services with varying requirements.

Innovation Solution

The implementation of grouped scheduling based on service groups, where each service group corresponds to a specific scheduling request resource, allowing the radio access network device and terminal device to perform efficient scheduling and processing of multiple service types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing resource scheduling mode is used for diverse services, then resource allocation can be performed, but service processing efficiency is reduced due to inability to perform appropriate scheduling for different service requirements

Engineering Contradiction:
Improveservice processing efficiencyVSAvoidservice type adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent divides services into different service types (e.g., delay-sensitive services and delay-tolerant services) and allocates different scheduling request resources to each service type. This segmentation allows the system to handle diverse service requirements efficiently by treating each service type separately with appropriate scheduling parameters, thereby improving service processing efficiency while maintaining adaptability to different service needs.

Inventive Principle:
Principle #1Segmentation

2Productivity

If separate scheduling request resources are allocated for each service type, then service processing efficiency is improved, but resource allocation complexity increases

Engineering Contradiction:
Improveservice processing efficiencyVSAvoidscheduling resource configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent configures multiple scheduling request resources with different parameters (such as different periodicities) that can serve multiple service types. For example, a first scheduling request resource with a first periodicity can be used for delay-sensitive services, while the same or different resources with adjusted parameters can serve delay-tolerant services. This multi-functionality approach allows efficient handling of diverse services while avoiding excessive complexity in resource configuration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple scheduling request resources with different parameters are configured, then adaptability to different service requirements is improved, but system complexity increases

Engineering Contradiction:
Improveservice requirement adaptabilityVSAvoidscheduling system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by configuring specific scheduling request resource parameters (such as periodicity, timing, and frequency resources) according to the local requirements of each service type. For instance, delay-sensitive services are allocated resources with shorter periodicity to ensure rapid response, while delay-tolerant services use resources with longer periodicity. This localized optimization allows the system to adapt to different service requirements without uniformly increasing complexity across all resources.

Inventive Principle:
Principle #3Local quality
