Solution Overview

Problem

Existing communication systems face challenges in managing configured grant (CG) resources efficiently, particularly for services like XR, which require flexible and accurate management of CG resources to meet high throughput and low latency demands.

Innovation Solution

A method where a terminal sends indication information to a network device about the usage states of CG resources, determined by the number of bits of the indication information and/or configuration information, allowing accurate and flexible reporting of resource states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the terminal reports the usage states of all configured grant resources, then the network device can accurately manage resources, but the signaling overhead and complexity increase

Engineering Contradiction:
Improveresource state indication accuracyVSAvoidindication information complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the resource state indication by dividing CG resources into different groups (first CG resources and second CG resources) with different indication methods. Some resources are indicated explicitly while others are indicated implicitly or by default, reducing the overall signaling complexity while maintaining accurate resource state tracking

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by indicating only the necessary subset of resource states rather than all possible states. The terminal determines a first number of CG resources to indicate based on actual usage patterns, reporting only those resources that require explicit state indication while leaving others to default assumptions

Inventive Principle:
Principle #16Partial or excessive action

2Adaptability or versatility

If the terminal determines the number of CG resources based on indication information bits, then the flexibility of resource management improves, but the processing complexity increases

Engineering Contradiction:
Improveresource management flexibilityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring the relationship between indication information bits and the number of CG resources. The terminal uses pre-defined rules and formulas (e.g., N = 2^M where M is the number of bits) to determine resource counts without complex real-time calculations, maintaining flexibility while reducing processing complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes parameters by allowing the number of CG resources to be dynamically determined based on the number of indication bits and configuration information. The system adjusts the resource count parameter N based on available signaling resources and service requirements, achieving adaptability through parameter variation rather than structural complexity

Inventive Principle:
Principle #35Parameter changes

3Productivity

If more CG resources are indicated with fewer bits, then the signaling efficiency improves, but the measurement precision of resource states decreases

Engineering Contradiction:
Improvesignaling efficiencyVSAvoidresource state indication precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent applies partial action by having the terminal determine a first number of CG resources (N) that is less than or equal to the total number of configured resources. This selective indication approach reports only the necessary subset of resource states with the available bits, maintaining precision for critical resources while improving overall signaling efficiency

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent applies local quality by allowing different precision levels for different resource groups. Some CG resources receive explicit state indication with higher precision, while others use implicit or default indications with lower precision, optimizing the overall system efficiency by matching indication quality to actual resource importance and usage patterns

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure relates to methods for determining a resource state, apparatuses, and a storage medium. A method comprises: a terminal device sending indication information to a network device, wherein the indication information can be used for indicating the resource use state of N CG resources, and N can be a natural number determined according to the number of bits of the indication information and/or configuration information received from the network device. In this way, the number of the CG resources indicated by the indication information can be accurately determined, thereby improving the flexibility and accuracy of state indication.
