Sidelink Feedback Request Determination for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, feedback mechanisms often consume excessive resources and can interfere with other communications, making them undesirable or unnecessary in certain scenarios.
Innovation Solution
A method and apparatus for determining whether to request feedback in sidelink communications, which involves a processor that decides on requesting feedback and transmits appropriate information to indicate the request and resources for feedback to the corresponding sidelink device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feedback is requested for all sidelink communications, then communication reliability is improved, but resource consumption increases and interference with other communications occurs
Solution Approach 1:
The patent applies local quality by differentiating feedback request behavior based on the specific characteristics of each sidelink communication. The determining logic evaluates parameters such as transmission direction (unicast vs. groupcast), QoS requirements, and communication scenario to selectively enable or disable feedback requests. This ensures feedback is requested only where necessary, optimizing the balance between reliability improvement and resource consumption reduction.

Solution Approach 1:

This ensures feedback is requested only where necessary, optimizing the balance between reliability improvement and resource consumption reduction.
3Loss of energy
If feedback is not requested for any sidelink communications, then resource consumption is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the feedback request parameter based on evaluated communication conditions. The determining logic considers multiple parameters including transmission type, QoS parameters, and communication scenario to make intelligent decisions about whether to request feedback. This allows the system to optimize the balance between resource consumption and communication reliability by changing the feedback request parameter adaptively rather than using a fixed approach.
