Terminal Data Transmission Priority Interface Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is that terminals which do not support simultaneous data communication on both the Uu interface and the Sidelink interface face conflicts when they have data communication requirements on both interfaces simultaneously.
Innovation Solution
The solution involves determining the highest-priority data for each interface when simultaneous data communication requirements are present, comparing the priorities, and sending data through the interface corresponding to the higher-priority data.

Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal supports data communication on both Uu interface and Sidelink interface simultaneously, then the communication versatility is improved, but the device complexity increases and conflict management becomes difficult
Solution Approach 1:
The terminal segments the data transmission function by separating the decision-making logic for different interfaces. It identifies highest-priority data on each interface independently, then uses a priority comparison mechanism to select which interface transmits data, avoiding the need for complex simultaneous transmission control
Solution Approach 2:
The terminal changes the parameter of interface selection from simultaneous operation to sequential operation based on priority. By dynamically adjusting which interface is active for transmission based on data priority comparison, the system maintains versatility while reducing complexity through parameter-based control
2Productivity
If the terminal prioritizes data transmission on one interface over the other, then the data transmission efficiency is improved, but the loss of time for lower-priority data increases
Solution Approach 1:
The terminal performs preliminary identification of the highest-priority data on each interface before making the transmission decision. By pre-identifying which data has the highest priority on each interface and comparing these priorities, the system ensures that the most important data is transmitted first, minimizing time loss for critical communications
Solution Approach 2:
The system implements a feedback mechanism where the terminal continuously monitors data arrival and priority levels on both interfaces. When new data arrives or priorities change, the terminal re-evaluates and adjusts interface selection, ensuring that time loss is minimized by dynamically responding to changing communication requirements

AI summary
A data transmission method and device are disclosed. The data transmission method includes: when a terminal that does not support transmission of data at a first interface and a second interface simultaneously has data transmission requirements simultaneously at the first interface and the second interface, respectively determining highest priority data of each of the first and second interfaces; the terminal compares a priority of the highest priority data of the first interface with a priority of the highest-priority data of the second interface and determines an interface corresponding to higher priority data; and the terminal sends data through the determined interface.
