Solution Overview

Problem

Existing communication systems face challenges in managing configured grant (CG) resources efficiently, particularly for services like XR, which require flexible management of CG resources due to their periodicity and high throughput demands, leading to increased resource overhead and latency.

Innovation Solution

A method and apparatus for determining resource states by sending first indication information to indicate the usage state of CG resources, allowing terminals and network devices to flexibly manage CG resources, reducing unnecessary reporting and thus overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal sends indication information to report the usage state of CG resources, then the network device can accurately manage CG resources, but the resource overhead increases

Engineering Contradiction:
ImproveCG resource management accuracyVSAvoidresource overhead
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary indication information (resource usage state) from the terminal and transmits it to the network device, rather than transmitting all possible information. This selective extraction reduces the amount of data transmitted while maintaining the essential functionality of CG resource management.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements dynamic indication where the terminal sends resource usage state information adaptively based on actual resource utilization conditions. The indication is not continuously transmitted but only when necessary, making the system flexible and reducing unnecessary overhead while maintaining accurate resource management.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If the terminal autonomously uses CG resources without scheduling, then the uplink service latency is reduced, but the resource utilization efficiency decreases

Engineering Contradiction:
Improveuplink service latencyVSAvoidresource utilization efficiency
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The patent establishes a feedback mechanism where the terminal reports the usage state of CG resources to the network device. This feedback allows the network device to monitor and optimize resource allocation, improving resource utilization efficiency while maintaining the low-latency benefits of autonomous CG resource usage by the terminal.

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure relates to a method for determining a resource state, an apparatus, and a storage medium. The method comprises: determining whether a terminal sends first indication information to a network device, the first indication information being used for indicating the resource use state of at least one configured grant (CG) resource. In this way, the terminal can more flexibly send the first indication information, thereby reducing resource overhead brought by the first indication information.
