5G Data Multiplexing Transmission for eMBB-URLLC Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, especially in the URLLC scenario, there is a challenge in dynamically sharing resources between eMBB and URLLC services of different users, leading to resource overlaps and inefficient utilization of uplink transmission resources.
Innovation Solution
A data multiplexing transmission method where a base station sends URLLC service resource occupation information to a second terminal through a control channel, allowing the second terminal to perform data transmission processing based on this information, thereby avoiding resource overlaps and optimizing resource allocation.

Engineering Contradiction Analysis
1Productivity
If eMBB and URLLC services dynamically share resources, then resource utilization efficiency is improved, but resource overlaps occur leading to transmission conflicts
Solution Approach 1:
The base station performs preliminary actions by allocating eMBB resources first, then checks for URLLC resource conflicts before finalizing the allocation. When a conflict is detected, the eMBB resource allocation is adjusted in advance to prevent transmission conflicts, ensuring both high resource utilization and reliable transmission.
2Speed
If URLLC resources are allocated with wider bandwidth and subcarrier interval, then transmission speed is improved, but resource overlap with eMBB increases
Solution Approach 1:
The system dynamically adjusts resource allocation based on service type. URLLC services are allocated resources with wider bandwidth and subcarrier intervals for high-speed transmission, while eMBB services use narrower allocations. The base station dynamically checks for overlaps and adjusts allocations in real-time, allowing the system to adapt to different service requirements while managing resource coordination.
3Productivity
If resource allocation is performed without checking occupation information, then allocation speed is improved, but resource conflicts increase
Solution Approach 1:
The base station implements a feedback mechanism where it checks the occupation information of allocated resources before finalizing the allocation. When a resource conflict is detected, the system provides feedback to adjust the allocation. This feedback loop ensures that resource conflicts are detected and resolved while maintaining efficient allocation through automated conflict detection and resolution.
