Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing multi-stream data transmission systems, when resources of the access link of a base station and a WiFi AP are available, multi-stream transmission is enabled without considering the availability of wireless backhaul link resources, leading to reduced data transmission rates and an inability to provide high-speed user service experiences.
Innovation Solution
A multi-stream data transmission system that includes an anchor configured to obtain resource availability data of all data transmission paths, determine multiple target data transmission paths based on this data, and transmit service data using these paths, ensuring that wireless backhaul link resources are utilized effectively between access nodes and the anchor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-stream transmission is enabled when access link resources are available, then network capacity and user service experience are improved, but data transmission rate decreases when backhaul link resources are insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the anchor detects backhaul link resource availability and sends control messages to access nodes to dynamically adjust transmission parameters. This feedback loop ensures that multi-stream transmission is enabled only when backhaul resources are sufficient, preventing rate degradation while maintaining high network capacity utilization.
Solution Approach 2:
The system dynamically adjusts transmission parameters including modulation and coding schemes (MCS), resource block allocation, and stream activation based on real-time backhaul link conditions. This dynamic adaptation allows the system to optimize between network capacity and transmission rate depending on current resource availability.
2Productivity
If multi-stream transmission is enabled without considering backhaul resource availability, then wireless access resources are fully utilized, but congestion and packet loss occur due to insufficient backhaul resources
Solution Approach 1:
The anchor performs preliminary detection of backhaul link resource availability before enabling multi-stream transmission. By checking backhaul capacity in advance and pre-calculating optimal transmission parameters, the system prevents congestion and packet loss while maximizing wireless access resource utilization.
Solution Approach 2:
The anchor acts as an intermediary between access nodes and the core network, buffering and regulating data flow. It controls the rate at which data is forwarded to the core network based on backhaul capacity, preventing congestion at access nodes while maintaining high wireless resource utilization.
3Speed
If backhaul link resource detection is implemented, then data transmission rate and reliability are improved, but system complexity increases
Solution Approach 1:
The anchor autonomously detects backhaul link resource availability and performs self-configuration of transmission parameters without requiring complex external control systems. This self-service capability improves transmission rate while minimizing the need for additional system complexity.
