Solution Overview

Problem

In ultra-dense wireless networks, the conventional fixed allocation of access and backhaul resources is not adaptive to dynamic conditions, leading to suboptimal resource utilization and transmission efficiency, especially due to the lack of consideration for data transmission modes of user terminals.

Innovation Solution

Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent implements dynamic resource allocation by allowing wireless access points to flexibly allocate access and backhaul resources based on real-time network conditions, user terminal data transmission modes, and channel states. This transforms the fixed time-domain allocation into a dynamic system that adapts to changing conditions, thereby improving system resource utilization while maintaining implementation feasibility through standardized allocation frameworks.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the allocation parameters from fixed time-domain slots to flexible resource allocation ratios that can be adjusted based on user terminal data transmission modes (such as coordinated beamforming or joint transmission). By modifying these parameters dynamically, the system achieves higher resource utilization without significantly increasing implementation complexity.

If conventional fixed resource allocation is used, then allocation method is simple, but transmission efficiency is decreased due to lack of adaptability

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system transitions from static fixed allocation to dynamic adaptive allocation where resource allocation ratios are adjusted in real-time based on network conditions, user terminal positions, and data transmission modes. This dynamic approach enhances adaptability while controlling complexity through systematic decision-making frameworks.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where wireless access points continuously monitor network conditions, channel states, and user terminal performance to adjust resource allocation dynamically. This feedback-driven approach enables the system to adapt to changing conditions automatically, improving versatility without requiring overly complex manual configuration.

Inventive Principle:
Principle #23Feedback

3Device complexity

Core Design Contradiction:

Solution Approach 1:

The patent applies different resource allocation strategies tailored to specific user terminal data transmission modes (such as coordinated beamforming requiring different allocation than joint transmission). By customizing allocation parameters locally for each transmission mode and user terminal, the system optimizes transmission efficiency without requiring complete redesign of the overall allocation process.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system adjusts allocation parameters based on user terminal data transmission modes, changing resource allocation ratios to match the requirements of different transmission techniques. This parameter adaptation improves transmission efficiency while maintaining a unified allocation framework that does not significantly increase overall process complexity.
