Solution Overview
Problem
Next-generation communication systems face inefficiencies in transmitting and receiving control data and user data between multiple Base Stations (BSs) or Relay Stations (RSs) due to reliance on a single backhaul link, which restricts data transmission efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single backhaul link is used for relaying signals between BSs or RSs, then the system structure is simple, but data transmission efficiency decreases due to restrictions
Solution Approach 1:
The patent divides the single backhaul link into multiple separate backhaul links, allowing simultaneous communication with multiple BSs or RSs. This segmentation enables parallel data transmission paths, thereby improving overall data transmission efficiency while distributing the communication load across multiple independent links.
Solution Approach 2:
The patent transitions from a single-dimensional communication path to multi-dimensional communication paths by establishing multiple backhaul links in different spatial or logical dimensions. This allows the system to communicate with multiple nodes simultaneously through diverse paths, enhancing productivity without proportionally increasing complexity.
2Productivity
If multiple backhaul links are used for communication with multiple BSs or RSs, then data transmission efficiency improves, but system complexity increases
Solution Approach 1:
The MLRS is designed with multi-functionality to handle multiple backhaul links simultaneously, performing routing, switching, and protocol management across diverse communication paths. This universal design allows the system to manage complex multi-link operations through a unified architecture, improving productivity while controlling complexity through functional integration.
Solution Approach 2:
The MLRS acts as an intermediary node that mediates communication between multiple BSs or RSs through multiple backhaul links. It manages the complexity of multi-path communication by providing a centralized control point that handles routing decisions, link management, and data forwarding, thereby enabling high productivity without proportionally increasing overall system complexity.
3Adaptability or versatility
If multiple communication paths are used, then network coverage and capacity increase, but inter-cell interference management becomes more difficult
Solution Approach 1:
The patent implements dynamic link selection and resource allocation mechanisms that adapt to changing network conditions. The MLRS can dynamically adjust which backhaul links are active, modulate transmission parameters, and reallocate resources based on interference levels, thereby expanding network coverage and capacity while managing inter-cell interference through adaptive control.
Solution Approach 2:
The system incorporates feedback mechanisms where the MLRS monitors interference levels, link quality, and network status across multiple communication paths. Based on this feedback, it adjusts routing decisions, modulates transmission power, and reallocates resources to maintain optimal performance, enabling expanded coverage and capacity while actively managing inter-cell interference through continuous adaptation.

AI summary
An apparatus and method for transmitting and receiving control data and user data between multiple communication stations using multiple backhaul links in a communication system, in which a Multi-Link Relay Station (MLRS) generates multiple backhaul links for data transmission/reception between multiple communication stations, and provides a multi-homing service for mobile stations using the generated multiple backhaul links. The MLRS may also support a handover for mobile stations using the multiple backhaul links. The use of multiple backhaul links facilitates efficient transmission/reception of control data and/or user data between multiple base stations or multiple relay stations.
