Terminal Feedback Rescheduling for Non-Uplink Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, conflicts between network instructions lead to resource waste and communication interruptions, affecting quality due to the terminal device's inability to determine which instruction to follow.
Innovation Solution
The terminal device sends feedback information on a second resource in a later time unit if the first resource is non-uplink, ensuring sufficient uplink resources are available, thereby reducing resource waste and transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal device sends feedback information on the first resource in the first time unit, then the feedback is transmitted in a timely manner, but if the first resource includes non-uplink resources, the feedback cannot be sent causing resource waste and communication interruptions
Solution Approach 1:
The patent implements dynamic resource selection for feedback transmission. The terminal device determines whether the first resource includes non-uplink resources and dynamically switches to a second resource in a second time unit if needed. This dynamic adaptation ensures feedback is always transmitted on valid uplink resources, resolving the contradiction between timely feedback transmission and communication reliability.
2Reliability
If the terminal device waits for a second time unit to send feedback information, then resource conflicts are avoided, but transmission delay increases
Solution Approach 1:
The patent applies preliminary action by pre-determining the timing relationship between the first and second time units. The network device configures the terminal device with advance knowledge of when the second time unit occurs, allowing the terminal to prepare for potential feedback rescheduling without actual delay. This preliminary configuration minimizes the impact of time loss while ensuring resource allocation reliability.

AI summary
This application provides an information transmission method and a communication apparatus. The method includes: A terminal device determines a first resource in a first time unit, where the first resource carries first feedback information, and the first feedback information is feedback information of first data; and the terminal device sends the first feedback information to a network device on a second resource in a second time unit in the case that the first resource includes a non-uplink resource, where the second time unit is a time unit later than the first time unit in time.
