5G Terminal Numerology Selection by Service Attributes

The patent implements dynamic numerology selection where the terminal device can switch between multiple configured numerologies based on service attributes. The numerology determination unit dynamically selects the appropriate numerology for different services (e.g., eMBB, URLLC, mMTC) rather than using a fixed configuration, thereby improving system transmission flexibility while managing device complexity through automated selection mechanisms.

The patent changes the numerology parameter according to service attributes such as data volume, quality of service level, and service type. By varying key parameters like subcarrier spacing and TTI duration based on service requirements, the system achieves flexible transmission adaptation without requiring complex manual configuration, resolving the contradiction between flexibility and device complexity.

The terminal device performs self-service by automatically determining the appropriate numerology based on service attributes without requiring network-side configuration for each numerology. The numerology determination unit internally processes service information and selects the optimal numerology, reducing the burden on network devices and simplifying the overall system architecture while maintaining high flexibility.

The patent creates a universal numerology determination mechanism that handles multiple service types (eMBB, URLLC, mMTC) through a single integrated unit. This multi-functional approach allows the terminal device to manage diverse numerology requirements uniformly, improving flexibility while avoiding the complexity of separate handling mechanisms for each service type.

The patent extracts key service attributes (data volume, quality of service level, service type) from the complex service information and uses only these essential features for numerology determination. By taking out only the necessary information elements, the system achieves high adaptability to diverse services while minimizing the amount of information that needs to be exchanged between terminal and network devices.

The patent applies partial action by selecting only the most critical service attributes needed for numerology selection rather than processing all available service information. This approach provides sufficient adaptability for different service requirements while reducing information exchange complexity by focusing on essential parameters rather than comprehensive data processing.
