Solution Overview

Problem

Current wireless network technologies lack an effective solution for reasonably utilizing multiple sets of non-dynamically scheduled transmission resources to adapt to different service types, such as URLLC and VoIP services, leading to inefficient resource management.

Innovation Solution

A method and apparatus for a terminal to receive information on transmission resource configurations and send data using configured resources, which includes dynamically and non-dynamically scheduled resources, allowing the terminal to determine the most suitable resources based on service requirements, priority, and traffic volume, ensuring efficient data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sets of non-dynamically scheduled transmission resources are configured simultaneously to adapt to different service types, then the adaptability to different service requirements is improved, but the device complexity increases due to the need to manage and select among multiple resource sets

Engineering Contradiction:
Improveadaptability to different service typesVSAvoidcomplexity of resource management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by enabling the terminal to dynamically select among multiple pre-configured non-dynamic scheduling resource sets based on real-time service requirements, traffic volume, and priority levels. This dynamic selection mechanism allows the system to adapt to different service types (e.g., URLLC, eMBB, VoIP) without requiring complex real-time reconfiguration, thus improving adaptability while keeping device complexity manageable.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by pre-configuring multiple sets of non-dynamically scheduled transmission resources with different parameters (time-frequency resources, reference signal configurations, modulation and coding schemes, power control parameters) before actual data transmission. The terminal can then directly select from these pre-prepared resource sets based on service requirements, avoiding the need for complex real-time resource configuration and reducing device complexity during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If non-dynamic scheduling is used to increase effective transmission time by avoiding SR and BSR processes, then the productivity is improved, but the reliability decreases when service requirements change and resource reallocation is needed

Engineering Contradiction:
Improveeffective transmission timeVSAvoidreliability of resource allocation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent resolves this contradiction by introducing dynamic selection capability within a non-dynamic scheduling framework. The terminal can dynamically choose the most appropriate pre-configured resource set based on current service requirements, traffic volume, and priority, thereby maintaining high effective transmission time while ensuring reliable resource allocation that adapts to changing conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by configuring multiple resource sets with different parameters (time-frequency resources, reference signal configurations, modulation and coding schemes, power control parameters) and enabling the terminal to select appropriate parameter combinations based on service requirements. This allows the system to maintain non-dynamic scheduling efficiency while adapting to varying service conditions through parameter selection.

Inventive Principle:
Principle #35Parameter changes
