Solution Overview
Problem
In 5G communications systems, existing resource configuration methods fail to meet the diverse requirements of different services, leading to resource waste due to inadequate air interface design for various service types.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a unified resource configuration method is used for all services in 5G communications system, then the system complexity is reduced and ease of operation is improved, but resource utilization deteriorates and service requirements cannot be met
Solution Approach 1:
The patent segments resource configuration by introducing service-type-specific configuration parameters. Different resource configuration sets are defined for different service types (e.g., eMBB, URLLC, mMTC), allowing tailored resource allocation. This segmentation enables the system to meet diverse service requirements while maintaining manageable complexity through structured configuration management.
Solution Approach 2:
The patent implements dynamic resource configuration by enabling flexible selection and switching between different resource configuration sets based on service type and channel conditions. The system can dynamically adjust resource parameters such as subcarrier spacing, cyclic prefix length, and transmission time interval according to real-time service requirements, optimizing resource utilization while adapting to changing conditions.
2Ease of manufacture
If existing resource configuration methods are applied to all service types, then device complexity is reduced and ease of manufacture is improved, but adaptability to different service requirements deteriorates
Solution Approach 1:
The patent achieves universality by designing a multi-functional resource configuration framework that can accommodate multiple service types through a unified configuration structure. The system uses a common resource configuration set template that can be selectively instantiated with different parameters for different service types, enabling one system to serve multiple functions without requiring separate dedicated configurations for each service.
Solution Approach 2:
The patent applies parameter changes by modifying key resource configuration parameters (subcarrier spacing, cyclic prefix length, transmission time interval, resource block allocation) based on service type requirements. This allows the same base configuration structure to be adapted to different services through parameter adjustment, maintaining ease of implementation while achieving high adaptability across diverse service scenarios.
3Device complexity
If resource allocation does not prioritize logical channels, then scheduling complexity is reduced, but loss of time increases for high-priority services
Solution Approach 1:
The patent implements preliminary action by pre-defining service type categories and their associated resource configuration sets before actual resource allocation occurs. High-priority services are pre-identified and assigned dedicated resource configurations, so when allocation is needed, the system can immediately assign appropriate resources without complex real-time prioritization calculations, reducing both scheduling complexity and allocation time.

AI summary
This application discloses a resource scheduling method and apparatus. The method includes: obtaining, by a terminal device, a first resource configuration parameter from an access network device; determining, by the terminal device, whether a first logical channel LCH supports the first resource configuration parameter, where the first LCH is an LCH on which there is to-be-sent data; and if the first LCH supports the first resource configuration parameter, determining, by the terminal device, a resource of the first LCH based on the first resource configuration parameter. According to the resource scheduling method provided in this application, after obtaining the first resource configuration parameter, the terminal device determines the resource of the first LCH by determining whether a mapping relationship exists between the first LCH and the first resource configuration parameter, to map the first LCH to the resource that matches the first LCH. This improves resource utilization.
