User Equipment Uplink Data Transmission Priority Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment in traditional communication architectures cannot select the most suitable communication mode for uplink data transmission due to priority issues with overlapping uplink resources allocated by the base station, which affects the reliability and efficiency of communication modes like URLLC.
Innovation Solution
The user equipment determines the priority of data transmission by comparing first and second uplink grants, selecting designated resources for higher-priority data and transmitting accordingly, allowing flexible resource allocation for optimal communication mode selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user equipment determines communication mode according to uplink grant priority, then the uplink resource allocation follows base station control, but the user equipment cannot select the most suitable communication mode when uplink resources overlap in time
Solution Approach 1:
Instead of determining communication mode based on uplink grant priority (traditional approach), the patent inverts the logic by first determining data transmission priority based on communication mode requirements, then selecting uplink resources accordingly. This allows URLLC data to override eMBB grant allocations when needed, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The patent introduces dynamic communication mode selection that adapts to real-time data requirements. When URLLC data arrives, the system dynamically switches to URLLC mode even if eMBB grant has higher priority, making the communication mode selection flexible and responsive to actual transmission needs rather than static grant priorities.
2Productivity
If the user equipment follows dynamic grant priority over configured grant, then the base station's resource allocation is respected, but the URLLC data transmission is delayed when configured grant has higher data priority
Solution Approach 1:
The patent performs preliminary determination of data transmission priority before actual transmission. By evaluating communication mode requirements and data urgency in advance, the system prepares to select appropriate uplink resources, ensuring URLLC data can be transmitted immediately when priority dictates, rather than waiting for grant processing sequence.
3Adaptability or versatility
If the user equipment transmits according to uplink grant priority, then the resource allocation structure is maintained, but the applicability for different communication modes is limited
Solution Approach 1:
The patent introduces an intermediary determination step that evaluates data transmission priority based on communication mode requirements. This intermediary layer mediates between the base station's grant allocation and the actual transmission decision, allowing the system to maintain grant structure while adapting resource selection to specific communication mode needs.
Data Source
AI summary
A user equipment receives a first uplink grant and a second uplink grant from a base station. The first uplink grant assigns first uplink resources, and the second uplink grant assigns second uplink resources. The first uplink resources and the second uplink resources overlap within a time interval. The user equipment determines whether the transmission of second data has priority over that of first data. When determining that the transmission of the second data has priority over that of the first data, the user equipment determines one of the first uplink resources and the second uplink resources as the designated resources of the second data, and transmits the second data to the base station according to the designated resources within the time interval.
