UE Short Latency Data Transmission via Pre-Configured Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data transmission methods in intelligent transportation systems suffer from significant time delays due to the lengthy access process required for short latency services, which cannot meet the requirements for low latency data transmission.
Innovation Solution
A method and device that allow user equipment (UE) to notify an eNB of its capability for short latency service upon power-on, receive configuration information, and directly transmit short latency data to the eNB without performing an access process, using reporting and monitoring configurations to reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs an access process to access the server and build a data channel, then the data transmission can be established, but the time delay becomes too long to satisfy short latency service requirements
Solution Approach 1:
The UE performs preliminary actions by notifying the eNB of its short latency service capability and receiving reporting configuration information before actual data transmission occurs. This pre-configures the UE to skip the access process during actual data transmission, reducing time delay while ensuring reliable connection establishment.
Solution Approach 2:
The invention extracts and eliminates the access process from the data transmission procedure for short latency services. By removing this unnecessary step through direct transmission mechanisms (MAC CE or RRC connection), the patent reduces time delay while maintaining reliable data transmission establishment.
2Loss of time
If the UE skips the access process to reduce time delay, then short latency requirement is satisfied, but the data transmission reliability may be compromised
Solution Approach 1:
The eNB provides feedback through reporting configuration information and monitoring configuration information to the UE. This feedback mechanism ensures that the UE correctly identifies when to use direct transmission versus when to establish a data channel, maintaining transmission reliability while minimizing time delay.
Solution Approach 2:
The UE performs preliminary capability notification and configuration reception before data transmission. This pre-establishes the conditions for reliable direct transmission, ensuring that skipping the access process does not compromise reliability since the necessary configuration and authorization are already in place.
