Base Station Scheduling for Video Transmission Feedback Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video transmission methods in mobile communication networks face challenges with long feedback times, leading to underutilization of resources and data loss, as servers struggle to adjust video transmission in real-time due to delayed feedback from user equipment.
Innovation Solution
A method and device where a base station receives video data packets and feedback information, performs scheduling based on this information, and transmits the packets to the user equipment, reducing the need for further feedback to the server, thereby reducing feedback time and improving real-time performance by fully utilizing resources and minimizing data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server adjusts video transmission by receiving feedback information from user equipment, then the video transmission can be adapted to channel quality changes, but the feedback time is relatively long causing the server cannot adjust video transmission in time
Solution Approach 1:
The base station is introduced as an intermediary between the user equipment and the server. The base station receives feedback information from the user equipment and performs scheduling decisions locally without requiring the feedback to travel to and from the server, thus significantly reducing feedback time while maintaining adaptation capability
Solution Approach 2:
The base station performs scheduling decisions in advance based on received feedback information before the server would have processed the same feedback. This preliminary action at the base station level enables faster response to channel quality changes
2Speed
If feedback time is reduced by enabling base station scheduling, then real-time performance improves, but system complexity increases due to additional base station processing
Solution Approach 1:
The base station performs partial scheduling functions rather than the complete scheduling process. It handles specific scheduling decisions based on feedback information while leaving other scheduling aspects to the server, thus achieving faster response without excessive complexity
3Ease of manufacture
If the server transmits video data packets directly to user equipment, then transmission is simple, but resources are underutilized and data loss occurs due to delayed adjustments
Solution Approach 1:
The base station serves as an intermediary that enhances resource utilization by performing local scheduling based on feedback information. This intermediary function optimizes resource allocation and reduces data loss while maintaining the overall simplicity of the transmission architecture

AI summary
Embodiments of the present application provide a method and a device for video transmission, which relates to the field of communications and is able to reduce feedback time, thus realizing the purpose of fully using resources and reducing data loss. The method includes at least the following operations: a base station receiving a second video data packet sent by a server and first feedback information about a first video data packet sent by user equipment, performing scheduling process according to the first feedback information, and after the scheduling process, transmitting the second video data packet to the user equipment according to the result of the scheduling process.
