Solution Overview

Problem

Current communication systems face challenges in handling resource conflicts for segmented nominal PUSCHs, leading to resource wastage and unnecessary delays in 5G IIoT scenarios, where resources allocated to the same terminal may conflict in time, especially in service scenarios sensitive to latency and Quality of Service requirements.

Innovation Solution

A method and apparatus that identify a fourth PUSCH within a first PUSCH that does not overlap or conflict with a second PUSCH, allowing data transmission over the fourth PUSCH for repeated transmissions, thereby clarifying conflict handling and optimizing resource utilization to avoid delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a first PUSCH and a second PUSCH overlap or conflict in time domain resources, then resource conflict occurs leading to resource wastage and transmission delays, but if the first PUSCH is completely discarded due to conflict, then resource utilization decreases and transmission efficiency is reduced

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidtransmission efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The first PUSCH is segmented into multiple third PUSCHs based on time domain resources. When a resource conflict is detected between the first PUSCH and second PUSCH, only the conflicting portion is identified and excluded, while non-conflicting third PUSCHs are retained for data transmission. This segmentation approach resolves the contradiction by maintaining transmission reliability through conflict avoidance while preserving productivity by utilizing available non-conflicting resources.

Inventive Principle:
Principle #1Segmentation

2Speed

If available resources are fully utilized for repeated transmissions, then transmission speed increases, but resource conflicts may occur leading to segmentation and complexity in resource management

Engineering Contradiction:
Improvetransmission speedVSAvoidresource management complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The terminal autonomously performs resource conflict detection, segmentation of the first PUSCH into third PUSCHs, identification of non-conflicting fourth PUSCHs, and data transmission without requiring complex network-side coordination. This self-service approach enables fast transmission by immediately utilizing available resources while managing complexity through standardized conflict handling procedures at the terminal side.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure provides a resource conflict handling method and apparatus, a terminal, and a storage medium. The method includes: transmitting, when a first PUSCH and a second PUSCH overlap or conflict with respect to time domain resources, if there is a fourth PUSCH in a third PUSCH included in the first PUSCH that does not overlap or conflict with the second PUSCH with respect to time domain resources, a data block over the fourth PUSCH. The first PUSCH is configured for repeated transmissions of the data block. In this way, the problem of conflict handling in the conflict scenario where the third PUSCH is present can be clarified. Here, available resources can be used as much as possible, and the resource utilization can be guaranteed, such that traffic can be transmitted to a network device as quickly as possible to avoid the delay caused by the resource conflict.
