Frequency Band Segmentation for 5G Service Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in coexisting and efficiently providing different services, such as eMBB, URLLC, and mMTC, simultaneously, due to overlapping frequency bands and potential data loss when URLLC data is transmitted during scheduled eMBB times, leading to increased eMBB data loss and reduced transmission performance.
Innovation Solution
A method and apparatus that allow for the coexistence of different services by sharing or allocating parts of the frequency band, enabling simultaneous transmission of URLLC and eMBB data by adjusting scheduling and resource allocation, ensuring that URLLC data can be transmitted without emptying eMBB-scheduled frequency bands, thereby minimizing data loss and maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If URLLC data is transmitted during scheduled eMBB times, then URLLC transmission speed is improved, but eMBB data loss increases
Solution Approach 1:
The patent segments the frequency band into multiple subbands, allowing different services to be transmitted on different subbands simultaneously. This segmentation enables URLLC and eMBB to coexist by allocating specific subbands to each service, thereby improving URLLC transmission speed while preventing eMBB data loss through frequency domain isolation.
2Productivity
If different services share the same frequency band, then resource utilization is improved, but service coexistence becomes difficult
Solution Approach 1:
The patent applies local quality by assigning different transmission characteristics to different subbands. Each subband can be optimized for specific service requirements (e.g., URLLC or eMBB), allowing high resource utilization through frequency sharing while maintaining service coexistence through localized quality differentiation.
Solution Approach 2:
The patent introduces frequency domain segmentation as an additional dimension for service differentiation. By dividing the frequency band into multiple subbands, the system enables multiple services to coexist in the same time period but on different frequency resources, thus improving both resource utilization and service coexistence.
3Reliability
If eMBB-scheduled frequency bands are emptied for URLLC transmission, then URLLC reliability is improved, but eMBB transmission performance deteriorates
Solution Approach 1:
The patent segments the frequency band into multiple subbands, allowing URLLC to be transmitted on specific subbands without completely emptying the eMBB-scheduled frequency bands. This segmentation enables URLLC reliability to be improved through dedicated frequency resources while maintaining eMBB transmission performance on other subbands.
